When your car breaks down, or just needs some routine service, it can make you a little nervous. Because your car’s so important to your life, you need to be back on the road as soon as possible. And, with the problem fixed right the first time.
It’s amazing how much knowledge and skill goes into diagnosing and repairing a modern car. So it’s not like when your uncle worked on his hot rod over weekend.
Today there are four cylinder engines that make more power than the V-8’s in luxury cars 20 years ago. A new V-6 Toyota Camry could beat Sonny Crocket’s Ferrari in a race to 60 mph.
Our engines are more and more powerful and at the same time their fuel economy keeps inching up. And they’re so reliable. This is all due to engineering. But the advances come at the price of simplicity. Modern cars are so much more complex from a mechanical standpoint that it makes your head spin.
Then there’s the electronics. Some cars have several networked computers controlling most of the engine functions and many other vehicle functions as well. We take all of this sophistication for granted – but somebody has to fix it when it breaks.
It’s a real challenge for your local Houston Texas technicians to keep up. It requires a high level of commitment on the part of the auto technician and the service center as well. In addition to the training, there’s the financial commitment to purchase the diagnostic and repair tools as well.
So where do technicians go for training? There’re many sources. It’s usually a combination of formal classroom training, training provided in the service center by parts and equipment manufacturers, on-line courses and home study courses. There are many independent certifications available all the way up to Master Technician.
And AutoNetTV produces monthly training for service centers called The Pro Channel. If you were to watch the Pro Channel segment on re-flashing the engine control computer, you’d be amazed at how much is involved: special software, hardware interfaces and a tremendous amount of knowledge and skill.
Service centers have a lot of other resources available as well. No one can know everything, so service centers like Christian Brothers Automotive subscribe to data services, technical libraries and even on-line communities that can help them with they run into a difficult problem.
It’s like those medical diagnosis shows on TV. Here are the symptoms – what’s the diagnosis and treatment. Diagnosis is every bit as much an art as a science. As consumers we want everything to be simple, straight forward and cheap – and sometimes it just isn’t.
So, be more relaxed next time you take your car in. You really should trust your service advisor at Christian Brothers Automotive. You’re in good hands. The more you know, the more comfortable you can be with your automotive service decisions. Visit AutoNetTV.com to see more great auto tips videos about many service topics.
People in Houston have been hearing a lot about higher oil change intervals these days. Maybe you're wondering: What are the key issues?
Some new vehicle manufacturers are now recommending much higher oil change intervals than they have in the past. As much as 5,000 to 8,000 miles or more. This practice came under scrutiny when four of the largest new car manufacturers announced that owners were experiencing engine damage resulting from these higher oil change intervals.
The manufacturers' standard oil drain service for particular vehicles was scheduled at around 7,500 miles. People following these recommendations were experiencing engine damage. It turns out that oil sludge was building up. This caused small oil passages to clog and engine parts to fail.
What causes oil sludge? It's a factor of time and mileage. There are hot spots in every engine that cause oil burn off that leads to sludge. Also, water from normal condensation can build up in the oil. This water also creates sludge. Severe driving conditions lead to more rapid sludge formation.
Severe driving around Houston includes short trips under four miles or trips under ten miles in freezing conditions. The engine just doesn't get warm enough for the water in the oil to evaporate.
Severe conditions are at the heart of the problem. Stop-and-go driving, towing, dusty conditions, heavy loads, very hot or very cold temperatures, a car top carrier – these are all conditions that would suggest that the severe service schedule should be considered.
The severe service schedule has much shorter oil change intervals. People just need to honestly evaluate how they drive to determine if they should change their oil closer to the severe service schedule, or to the standard schedule.
Some types of car will give oil change reminders. But it's important to know how that reminder is determined. For some, the reminder simply comes when the standard mileage interval has rolled around. Others use a computer algorithm that takes into consideration the number of cold starts, trip length, engine temperature and so on. It's programmed to approximate where on the standard/severe service spectrum you fall. Some more expensive vehicles actually have sensors that test the cleanliness and effectiveness of the oil.
For the rest of us, better safe than sorry should be the guiding principle. Talk with your service advisor at Christian Brothers Automotive and work it out together. Find out what kind of oil the factory sends out in your vehicle. Sometimes it's a premium grade that costs more than standard oil – but it may be what's needed to meet a higher factory recommended interval.
If you're realistically conservative, standard grades of oil will take care of you year after year. If you want to push the limits, ask for a premium grade oil to give you extra protection.
So, what happened with those manufacturers with the problems from higher oil change intervals? They ended up extending the engine warranty for parts that were affected by oil sludge. But they had a stipulation – they lowered the oil change interval and the vehicle owner had to provide proof of oil changes at the new lower interval to keep the extended warranty.
Buying a new car is always a big financial decision. The allure of that new car smell is powerful, to be sure. But what if your current car is still in good shape? How do you decide?
People in Houston who've been used to driving a new car every three to five years may be having second thoughts in this economy. For many, the question is, how does the certainty of a new car payment stack up against uncertain repairs for a car that may be out of warranty?
For purposes of our discussion, let's assume you have a five year old vehicle. It's now paid off. If you keep it, you fear that there'll be some repairs over the next five years, but you really don't know what to expect. For help we turned to Edmunds.com.
Edmunds.com has compiled maintenance and repair information for cars and trucks. With this data, they project likely service and repair costs for a particular make and model. They're able to use manufacturer's maintenance schedules and repair histories for the projections.
Of course, these projections can't predict what will happen to your vehicle in Houston, but they do give you information to use in your decision.
Let's look at the numbers for a five year old Toyota Camry V-6. In this example, the combined maintenance and repairs for the five year period is $5,748. This works out to an average of $96 a month. The year-by-year averages range from a low of $49 a month to $124 a month.
So compare $96 a month with a new car payment. And it's actually better news than that; you would still have maintenance expenses with a new car, so the repair element could be less than half that figure.
Here are numbers for some other five year old vehicles:
Ford Escape - $116 a month
Chevy Silverado - $131 a month
Jeep Grand Cherokee - $138 a month
Hyundai Accent - $85 a month.
Now, if your vehicle is older than five years, have a chat with your service advisor at Christian Brothers Automotive. We see hundreds of vehicles through our bays every month and we know your car. See if there's any particular problem common with your vehicle that you might see over the next couple of years.
And of course, the best way to keep future repair costs down is to take care of all your scheduled maintenance. This is especially important in older vehicles that have had time to accumulate some deposits.
There are special motor oil formulations that help clean older engines and protect and recondition their seals and gaskets.
We hope this eliminates some of the unknowns in the decision to keep or trade.
The government mandates a lot of equipment on cars: emission devices and control computers, safety equipment like airbags and crash worthiness requirements. All of this is great for the motoring public, but it does add quite a bit to the price of a new car.
Because new cars are more expensive, people are driving their old cars longer. The average car is now over nine years old. Two thirds of vehicles on the road have more than 75,000 miles. As cars age, their performance drops, they have difficulty idling for long periods and are more sensitive to weather extremes. Fortunately today's cars are up to the challenge – but they need a little help to keep on goin'.
Some owner's manuals don't specify service requirements at higher mileage. That doesn't mean it doesn't have to be done. In fact, it's more important than ever to stay on top of routine maintenance for cars with more than 75,000 miles.
First, just extend regular service intervals out: for instance a service that's recommended every 15,000 miles should be performed at 15,000, 30,000, 45,000 and 60,000 miles, and so on. Because of the additional stress older engines experience, the severe service maintenance schedule is more appropriate than the regular schedule – ask your service advisor. Watch for leaks – seals and gaskets dry out over time and don't hold the fluids as well as they used to.
It's also time to make sure you have a good technician. There are some services and replacements that are scheduled after you put on some clicks, like timing belts, valve train adjustments, suspension, anti-lock brake service, air bags, etc. And unexpected repairs down the road are just par for the course. Check for unusual sounds, smells or the way your car feels. These could be hints that trouble's brewing. Better to catch it early before it turns into a costly repair.
And a regular wash and wax will help maintain your car's appearance. One of the things you can do to really help your high mileage vehicle is to begin using high mileage formulation fluids. There are special engine oils, coolants, and transmission and power steering fluids that are formulated for cars that have a few clicks on the old odometer.
High mileage oil is designed to condition seals and gaskets, reduce wear and avoid premature burn off. Older engines are dirtier inside – and dirty engines contaminate their oil faster. High mileage oil has special additives that clean the engine, removing sludge deposits over time. The result is less stress on the engine, better fuel economy and excellent wear protection.
Studies have even shown that using high mileage fluids early will actually prevent some of the problems of high mileage vehicles. So once you hit around 50,000 miles, consider stepping up to high mileage formulations. High mileage fluids cost a bit more than standard fluids because of the additional additives, but they can be worth their weight in gold in terms of preventing repair costs down the road. It does cost more to properly maintain a higher mileage vehicle – but it's way cheaper than a new car payment!
Bad air quality while you're driving is nothing to sneeze at. But seriously, more and more vehicles these days come equipped with a cabin air filter. Since they're fairly new on the scene, a lot of folks don't know about them yet.
These filters clean the air in the passenger compartment, or cabin, of your car or truck. They do the same job as the furnace filter you have at home. They can filter out particles as small as thee microns. By contrast, a grain of sand is about 200 microns.
So your cabin air filer can clean out dust, pollution, pollen and spores, to keep the air in your car nice and clean. And just like your furnace filter, they need to be replaced when they get dirty. Check your owner's manual, but they typically need to be replaced at around twelve to fifteen thousand miles.
The filter is usually either under the hood or under the dashboard. Some are a little tricky to get to, so you'll want to have your service center, Christian Brothers Automotive, take care of replacing them.
As we said, many people don't realize they have a cabin air filter and go to their shop complaining about a funky smell in the ventilation system. It turned out to be a cabin air filter that was long overdue for replacement – really dirty and starting to smell. A quick replacement and they were on their way and smelling fine.
People who are allergy sensitive can really benefit from a cabin air filter, as it keeps allergens to a minimum. If you're one of them, you'll want to stay on top of your filter replacement schedule.
Of course if you do a lot of driving in dusty or polluted conditions, you'll need to change your cabin air filter more often.
At Christian Brothers Automotive we’ve had a lot of people asking how they can make their vehicles last longer. These questions are actually a reflection of a trend that’s been building for several years. The median age of personal vehicles is now over nine years. And 33 percent of all vehicles on the road have over 75,000 miles on them. It looks like it’s going to keep heading in that direction for a while. With high fuel prices a lot of folks are putting off buying a new car. Thanks to AutoNetTV, we can provide you with a video answer to this question.
So let’s say you’re one of the average people; you’ve got a nine year old car with 80,000 miles on the odometer. What can you to do make it last another year or two?
Let’s start with the premise that there’s no reason that a modern car can’t run for 200,000 miles with proper care. The engineering and manufacturing quality is there.
Of course, some parts will wear out along the way, but there’s no reason for a catastrophic meltdown if you stay on top of your recommended maintenance. The maintenance schedule in some owner’s manuals runs out at 60,000 miles or so: how do we know what to do when we’re way past that?
It is a challenge, for example: If a service is recommended every 15,000 miles for the first 60,000 miles you can just keep getting it done at least every 15,000 miles after you hit 60,000 miles. But, it gets more complicated because older engines lose some efficiency, are dirtier inside and are just more stressed. That means it’s very important to not miss any scheduled services. Skipping just one oil change, for example, leaves an opportunity for harmful sludge to build up.
So all the usual things like oil changes, transmission service, coolant service, brakes, power steering, fuel system cleaning – all that stuff need to be maintained. People responsible for fleet vehicles around Houston are positively religious about scheduled maintenance. They know that money spent on maintenance saves them three ways:
it saves fuel;
it prevents costly repairs, an;
they can postpone purchasing new vehicles.
Having the oil changed may be the most important thing. A full service oil change means that all of your other fluids get topped off so they are never low enough to cause damage. It also gives your technician a chance to spot problems in the early stages so that you can fix them before they get expensive. And it gives you a touch point with a professional along the way to remind you of things that aren’t scheduled as often – things like differential service and timing belt replacement.
If you have an older vehicle, you may need to follow the severe service maintenance schedule. Check your owner’s manual and talk with your service advisor at Christian Brothers Automotive. Conditions inside an older engine, transmission and cooling system can arguably be considered severe – so shorter intervals could well be called for.
And, we would strongly encourage you to consider using high mileage formulation fluids. They’re fluids like engine oil, transmission fluid and coolant that are formulated for older engines. They have special additives to clean deposits, and to condition and restore seals and gaskets that dry out with age. Some people start using higher mileage formulations at around 50,000 miles as a preventive measure.
Of course you also want to still look marvelous in your older car. Salt and road grime wreak havoc on your paint job and can lead to body rust – so regular washing is very important. Also, a good quality waxing is recommended at least twice a year.
You may know that all 2008 model year and newer cars, mini-vans and light trucks come with a tire pressure monitoring system. Many slightly older vehicles around Houston have these systems as well. A tire pressure monitoring system – called TPMS – consists of sensors on each wheel that measure tire pressure.
If tire pressure drops 25 percent below the manufacturer’s recommended pressure, the sensor sends a signal to a monitoring unit that causes a warning to light up on the dashboard. When you see the warning light, you know it’s time to put some air in your tires.
There are many benefits to driving with properly inflated tires. First is cost savings. Running at the correct air pressure improves fuel economy. Driving on under-inflated tires is like driving through sand – it drags down your fuel economy. You’ll also see longer, more even tread wear so your tires’ll last longer.
Another important benefit of properly inflated tires is increased safety. Under-inflated tires become hotter and that heat can actually lead to tire failure – possibly resulting in an accident. Your car and the tires themselves will just perform better and more safely around Houston with properly inflated tires.
Consumer groups, law-makers and vehicle manufacturers advocate TPMS systems hoping that they will save lives, property damage and inconvenience. While you can’t put a value on saving a life, we keep in mind that TPMS systems will carry a cost.
The systems themselves are added into the price of the car. The batteries in the sensors will have to be replaced from time to time. Parts will break and need to be replaced. In colder climates, ice and salt are frequent causes of failure.
In addition, there are other behind-the-scenes costs to be aware of. Every time a tire is replaced, repaired, rotated or balanced, the tire technician has to deal with the TPMS system.
Your service center (Christian Brothers Automotive) must purchase equipment used to scan and reactivate the TPMS system after every tire service. Because older tire change equipment can damage TPMS sensors, your service center may need to buy expensive, new tire changers.
Since there is no uniformity among manufacturers, technicians need to be trained on several TPMS systems. These behind-the-scenes costs are very real to your service center.
That’s why they are anxious for you to understand the financial impact of TPMS systems. In the past, they’ve been able to quickly and cheaply provide tire services, and then pass the low cost on to you as an expression of their good will. But now even these simple jobs will take much longer.
Sensors will need to be removed and reinstalled. Even a tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed.
So when you start so see the cost of tire changes, flat repairs and rotations going up, please keep in mind that it’s because of this new safety equipment. Christian Brothers Automotive just wants to keep you safely on the road – and we're committed to do so at a fair price.
It’s important to remember that the TPMS warning only comes on when a tire is severely under-inflated. You’ll still want to check your tire pressure on a regular basis. At every fill-up is best, but you should check pressure at least once a month. Here’s wishing you safe travels.
Today we're talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.
A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.
So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they've had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That's the fuel filter's job.
When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner's manual or ask your service advisor if your fuel filter is due for replacement.
The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.
It's real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can't do that if they're dirty. Dirty fuel injectors really rob power and waste fuel.
It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it's burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it's dirty.
The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it's dirty as well.
Do all these things and your engine's air and fuel will be as clean as possible. You'll get much better fuel economy and better power
Life's full of surprises, some of which cost money. A leaky roof, a broken tooth, or an unexpected car repair. Christian Brothers Automotive and AutoNetTV have done some research on how we can budget for proper vehicle care.
Everyone does our best to budget for scheduled vehicle maintenance. What's hard is unexpected repairs. The truth is that our vehicles can stay on the road longer than ever before with proper maintenance. That's because of improved vehicle design and manufacturing quality. But some of those same improvements also lead to higher repairs costs.
Let's take the fuel pump. Previous generations were often stranded by the side of the road by vapor lock. This occurred when the gas vaporized between the gas tank and the fuel pump. Fuel just stopped flowing.
You had to sit and wait until the car would start again. To alleviate the problem, fuel pumps are now located inside the gas tank. This is a great solution, but when the fuel pump fails, it's a much more expensive proposition to replace it.
Sealed wheel bearing assemblies are another example. These wheel bearings can't be serviced – you just have to replace the entire assembly when it starts to fail. That costs several times as much as service on non-sealed bearings.
So we all benefit from design improvements, but we need to plan for repairs down the road.
There's a tool that can be found on Edmunds.com that you can use to prepare your service and repair budget.
Let's suppose you have a 2003 Toyota Camry – a very popular car. It's now paid for and you'd like to keep it running for the next three years. You can go to Edmunds' True Cost to Own calculator and enter your vehicle's data. The calculator will provide estimates of what it'll cost to service and repair your vehicle over the next five years. The estimate is based on where you live or live near, and manufacturers' recommendations and repair experience for your particular model.
Of course these are just estimates – there's no way to predict what'll actually happen to the car in your driveway, but it's a good starting point.
The calculator also has estimates for depreciation, financing, insurance, taxes and fuel costs.
Let's focus on maintenance and repair. This table shows that the average monthly cost of maintenance and repairs is eighty-three dollars. That may sound like a lot, but compare it to a new car payment.
So if you set aside eighty-three dollars a month, you'd go a long ways towards taking care of routine maintenance and being prepared for the unexpected repairs that arise.
Of course, you can't predict when something will go wrong or what it'll cost, but at least you have a reasonable target to shoot for.
Some people are afraid of what can go wrong with their older car so they buy a new one. That's fine if you really want a new car, but if you properly maintain your older vehicle, you'll save a lot of money on new car payments and insurance. It just makes good economic sense.

Have you ever had an experience like this? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your check engine light started flashing!
You fear the worst, but within a block or two, the light stopped flashing, but stayed on. By the next day, the light was off.
You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.
Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.
Warning, warning! It flashes the check engine light, to alert you to take immediate action.
It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I'm still concerned, I'll keep this light on for now.
Then the Check Engine Light goes off in a day or two.
The condition never did recur, so the computer says whatever it was, it's gone now. The danger is past, I'll turn that light off.
Now a flashing check engine light is serious. You need to get it into our shop as soon as possible. But if it stops flashing, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?
Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air to fuel mix, spark advance, and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.
The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the check engine warning.
The computer will then try to make adjustments if it can. If the computer can't compensate for the problem, the check engine light stays on.
The computer logs a trouble code. Some people think the code will tell the technician exactly what's wrong?
Actually, the code will tell the technician what sensor reading is out of parameters. It can't really tell you why, because there could be any number of causes.
Let's say you're feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees.
You know your symptom – a fever – but you don't know what's causing it. Is it the flu, a sinus infection or appendicitis?
You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.
There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.
There are two problems with that. First, the computer stores some trouble codes in short term memory, and some in permanent memory. Each manufacturer's computer stores generic trouble codes, but they also store codes that are specific to their brand.
A cheap, generic scan tool, like you can buy or that the auto parts store uses, doesn't have the ability to retrieve long-term storage or manufacturer specific codes. Your service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.
The second problem is that once you've got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.
So the common solution is for the auto parts store to sell you a new oxygen sensor, which are not cheap, and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.
How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at Christian Brothers Automotive. Give us a call at 281-870-8900 and let us help you resolve your check engine light issue.
