If your car is overheating all the time, there is likely a problem with the cooling system. This being said, you may also be in desperate need of an oil change or have a fuel pump that is overheating. Premier Auto Repair is going to focus on the cooling system in this blog post. Listed below are the reasons why your car, truck, or utility vehicle is overheating all the time.
Clogged Cooling System
If your cooling system is clogged, coolant is not making its way through the engine and this will make your automobile overheat every time you drive it. The cooling system can corrode, as can the radiator. Any time there is an abundance of contaminants in the hoses or the radiator, you’ll end up with a clogged cooling system.
Coolant Circulation Problems
Clogs can cause this cooling system to have circulation problems but so can a malfunctioning water pump. If the water pump is not working as it should be, it may not be circulating coolant through your engine, and this is why your car keeps overheating. Water pumps last on average about 90,000 miles. If you drive a high-mileage automobile, it’s possible your water pump has failed.
Cooling Fan Failure
Once the coolant circulates through the engine, it is returned to the radiator where its temperature is reduced by air inlets and a cooling fan. If the cooling fan has gone bad, the water pump will circulate hot engine coolant through the engine. Obviously, it cannot cool down the engine if it is already hot.
Leaks in the System
If you have a leak in your radiator system, your coolant level will be reduced and your engine will overheat. It’s important to always check your coolant level on a regular basis to make sure your engine has enough coolant. The leak may be small enough that you don’t see spots on your garage floor yet the cooling system is starved of coolant.
As we mentioned above, the radiator can get corroded and rust as it ages. In some cases, the rust will eat through the bottom of the radiator and you will end up with a coolant leak. In this case, the coolant may look orange because it is filled with rust.
Finally, your engine will not get coolant until such time as the thermostat releases it. If the thermostat is malfunctioning or has failed completely, it may not be releasing engine coolant to the water pump so it can circulate it to keep your engine cool.
