Some drivers adore their babies (we mean their cars), while others either mostly enjoy their car or continue driving it simply because it’s paid off. No matter how much you enjoy your car, in order to keep it in top shape, regular maintenance is going to be a way of life. Sometimes, though, when you’re on the road, it can be difficult to catch a problem before it becomes a major issue. One of the most common issues drivers face is a coolant leak, and these can come out of nowhere.

At Christian Brothers Automotive, we think it's important for drivers to understand what a coolant leak is, why it may occur, and what can be done to both fix and prevent it. Keep reading to discover what our expert technicians believe you should know about coolant leaks!

What is a Coolant Leak?

Coolant, also known as antifreeze, is an essential fluid in your vehicle's cooling system that keeps your engine from overheating. If there is a hole or crack in any of the parts of the cooling system, such as the radiator or hoses, coolant can leak out, causing major issues for your car.

Where Does Coolant Leak from?

Many different components make up your vehicle's cooling system. Because of this, there are numerous places where a leak can occur. Common areas where these leaks develop include:

• Radiators

• Hoses

• Hose connectors

• Gaskets

• Water pump

• Thermostats

The easiest way to identify the specific area where the coolant leak is coming from is by popping your hood and seeing for yourself. If you're unable to locate the source of the leak or you're not comfortable doing it on your own, the mechanics at your local auto shop can help!

Why Does Coolant Leak?

Coolant leaks can happen for a number of reasons – too many to list them all here! However, some of the most common causes of coolant leaks include:

• Clogs from debris

• Low coolant levels

• Damage from wear and tear

• Faulty parts

• Cracks from age

While some coolant leaks can't be avoided, especially when caused by age or wear and tear, regular maintenance can help ensure your car runs smoothly and safely for years.

How Do You Identify a Coolant Leak?

Identifying a leak early is your best bet at avoiding damage to your engine. To identify a leak, check for the following signs:

• Pooling liquid underneath your car

• Discolored coolant (usually brown) on the driveway

• Steam in or around your engine bay

• An odd smell coming from under the hood (most customers describe it as a “sweet” smell)

• The car's temperature rising higher than usual

• White smoke coming from the exhaust

If you're unsure whether your coolant is the fluid that's leaking, you can always check the reservoir. If there's been a significant dip in the fluid's level, there’s likely a leak somewhere.

Can Coolant Leaks Cause Check Engine Lights?

Yes, coolant leaks can cause your check engine light to come on. A leak in the coolant system can lead to low coolant levels, which might trigger a warning light or cause the engine to overheat. Additionally, coolant leaks can impact the performance of various sensors and components, such as the thermostat or the oxygen sensor, leading to the activation of the check engine light.

What Happens if You Don't Fix a Coolant Leak?

If you ignore a coolant leak, you're setting yourself up for a world of problems. Coolant is essential in regulating your engine's temperature and ensuring it doesn't overheat or freeze. Without adequate coolant, your car won't be able to function properly and can suffer serious damage.

Other problems include:

• Your car overheating or freezing

• The smell of burning coolant entering the cabin

• Corrosion and rust in your engine

• Reduced fuel economy

Regardless of where your coolant is leaking from, any fluid leaks in your vehicle should be dealt with immediately. Coolant is often drained during repairs to the cooling system, so it’s very normal for a coolant flush to be recommended with such repairs.
