Why Does a Vehicle Overheat?

How to Prevent Your Vehicle from Overheating
Dealing with an overheating vehicle? Maybe you want to know how to prevent your vehicle from overheating. We can help you a little bit. Ultimately though, you may need service. Carl Black Hiram here in Hiram, GA, will tell you why, what you can do in the meantime, and what you should look out for.
What should you do when your vehicle is overheating?
There are a few things you can do to help your vehicle if it’s overheating while you are driving it. Ideally, you should stop driving it as soon as possible and let everything cool down. However, turning the heat on in your car (yes, the same heat that will blow hot air into your cabin) can actually help.
That’s because the heat in your cabin actually comes from the heat in your engine, so turning on your heater will potentially help draw more heat out of the engine. This is good if your car only seems to overheat while idling or if you just need to limp your car off a busy street.

The reason why the heater may only potentially help is if there is low or even no coolant in your car’s cooling system, then your heater will not do any good as you have larger issues with your car. However, you can refill your radiator with coolant. Be sure to only open your radiator cap when your engine is fully cooled and only add the correct coolant as listed by your manufacturer. Some manufacturers utilize different coolants that are not friendly with each other.

When is it time for service on an overheating vehicle?
If you notice coolant leaking out of your car, or if the coolant constantly needs to be refilled, then you need someone to look at the engine cooling system of your car. A leak could have sprung in one of your hoses, your radiator, or even your heater core. If it’s your heater core, then it’s possible coolant could be getting sprayed into your interior vent system. One way that this could be made apparent is if your windows seem to fog up from the inside and the fog seems more oily than just plain water.
