Engine Coolant is Low, Dirty or Leaking: You know your engine wouldn’t work without oil that’s in good condition. Turns out, the same is true of your engine’s coolant. Coolant is a fluid that’s necessary for cooling down the engine as it warms up during operation. When the engine’s coolant is leaking, you may see white exhaust smoke. This smoke means there’s an internal coolant leak, which may be due to a cracked cylinder head.
Dirty Air Filter: The air filter in your car works very similarly to the air filter in your home. When your AC unit has a dirty air filter, it’s very inefficient at pulling in air, doing so much slower than a clean filter. This means your home takes longer to cool down. It’s the same when it comes to your car. An engine with a dirty air filter may overheat. So, if your engine is overheating, think about the last time you had the air filter cleaned or changed out.
Loose or Broken Belt: The belt is the link that turns the water pump at the correct speed to ensure proper coolant flow through the cooling system. When belts become loose or break, the system can’t keep up a constant or proper speed. Inconsistencies in belt speed cause inadequate coolant flow, which, in turn, will make your engine overheat.
These are only a few of the possible reasons for why your engine is overheating. A car that overheats is a clear indication that something critical is wrong, and if the issue is ignored the outcome could mean major repairs later down the road. If an “overheating” light turns on and you don’t know what to do, don’t panic! Call your local Christian Brothers Automotive shop today.
