Why Is My Car Overheating?
Having your car engine overheat is no fun, it can be a costly engine killer that will leave you stranded on the side of the road and expensive repair bills from your mechanic. Below I have listed the most common reasons your car overheats.
Your thermostat is not opening: The first sign of a bad thermostat is when your car overheats at freeway speeds. Your engine needs a lot of coolant flowing through it, if the thermostat does not open your motor will not cool properly and you will find your self stranded along the roadside.
Broken fan belt: Most engines have a fan belt that drives the cooling fan for your engine. If the fan belt breaks it stops the fan from turning and your engine will overheat.
Low Coolant: The most common reason for your engine overheating is low coolant. The coolant in your engine is responsible for removing heat from your motor. If you coolant is low, heat will build up and your motor will overheat.
Clogged radiator: If your vehicle has more than 60,000 miles on it your radiator could face the problem of being gummed up. A gummed up radiator will slow the amount of coolant that circulates through it allowing your car to overheat. It is a good idea to get a radiator flush every 30,000 miles to reduce your chances of a clogged radiator.
Failure in your electric cooling fan: If your car has an electric cooling fan and it does not come on, this can lead to your car overheating. The electric cooling fan will draw air from your radiator when going at slow speeds to pull the heat off the radiator. If your car heats up at slow speeds there is a good chance your electric fan is not coming on.
Bad fan switch on your radiator: Your fan has a switch on it that tells it to come on when it reaches a certain temperature. If this switch is bad it will cause your car to overheat.
