The Radiator Fluid is Low

Radiator fluid, also called coolant, keeps the motor cool during operation. When your car beings to run out of coolant, your engine is unable to effectively transfer all the heat it produces, so it overheats. This is the first place to always inspect when your car engine is overheating. Simply refill with coolant and water, and that’s it! Your vehicle should be just fine. But if that’s not it…

The Radiator is Clogged

A clogged radiator happens overtime as grease and muck builds up inside. If a car has more than 50,000 miles on it, it is at higher risk for radiator clogs. To avoid this, be sure to have your vehicle’s radiator flushed on an annual basis. This is a cheap and quick service you can get at almost any auto shop or service station.

You Have a Coolant Leak

Perhaps your car is low on coolant because it has a leak in the radiator. When a car cannot sustain its coolant levels, it cannot properly regulate heat transfer in the engine. This causes a car to overheat. 

The Coolant Fan is Malfunctioning

On the topic of coolant, it could be that the coolant fan is defective or not operating properly. This part is easy to check. Simply pop the hood and the coolant fan is located on top, next to the radiator. See if the fan is sluggish or slow. If, so it could be the cause of your engine overheating problems. It could be the electric fan, or it could be the radiator switch. An Indianapolis mechanic can figure that out for you.

The Fan Belt Broke

A broken fan belt will cause a car engine to overheat rapidly. If the fan belt is broken, it is highly likely that other engine components are malfunctioning too. Mostly older vehicles have fan belts, but they are easy to repair. All you have to do to check for a broken fan belt is look at your car’s engine.

The Thermostat is Closed

If your vehicle’s thermostat will not stay open, then your car will overheat. This is because the thermostat controls the amount of coolant released while a vehicle is in operation. If it’s defective, it cannot read the temperature and open the coolant flow as needed. This will cause overheating issues quickly.
