Reasons Your Car Would Overheat
Submitted by Brenda
Having a car reason overheat can be one of the worst experiences in the world. Driving down the road and suddenly having steam shooting from beneath the hood of a car can be traumatic. Especially if you are miles from home and help. One thing that can help the experience be less of a shock is actually knowing and understanding the reasons why your car might overheat can make the experience less frightening. Being able to trouble shoot a problem, or at least rationalize, a situation can make things a bit easier to handle.There are several reasons that can cause a car engine to overheat at an unfortunate and inconvenient moment. Most of these reasons are related to coolant because the loss of coolant ultimately leads to the engine overheating. Since engines by nature generate some sort of heat all cars have a way to keep the heat from getting to be a problem.One of the first reasons that your car engine might over heat is a problem with the radiator cap. Most people that do find themselves in a car that is overheating seemingly for no reason at all can blame it on the radiator cap. The radiator cap is used to hold in pressure and if it is not working correctly the coolant can begin to boil causing the engine to overheat. This will sometimes happen to cars with absolutely no other problems simply because the radiator cap is removed for some reason and then not replaced correctly. Another reason your car might eventually overheat is because there is a coolant leak. The radiator boiling has already been mentioned and there are other reasons that the coolant in a car can leak. There are times when the hoses in the car can be damaged causing leaking. Also there is the chance that the water pump can stop working. Water pumps can be replaced and if you are unsure how to check your water pump you can always ask any auto mechanic that you know and trust to help you check or show you how to check it yourself. Problems in your cars exhaust system can also lead to your car engine overheating. Most exhaust systems can be discovered by checking your cars vacuum readings, pipes, and converter. Also it is important that you check your radiator hose to make sure that it has not collapsed because that can also lead to your car engine overheating. Your cars electric cooling fan also needs to be working correctly or else your car will over heat. It is important that you make sure that the fan motor is working correctly so that your car is cooled properly. In addition to keeping an eye on your electric cooling fan you should also make sure that your cars thermostat is working properly. The thermostat is usually the first warning you have for your car overheating. If your cars thermostat is working properly you will be able to stop your car and let it cool down before the overheating gets serious possibly buying time to get home or to a repair shop.
