Are you having trouble with your car overheating? It can be a frustrating problem to deal with and diagnose. This article will go over some of the most common reasons why cars and trucks overheat.
One of the most common reasons for a vehicle overheating is a stuck thermostat. It can stick or freeze in the closed position blocking the flow of coolant to your engine. The easiest way to check if your thermostat is not open is to feel the upper radiator hose. Once the engine warms up it should become warm. If it does not get hot the thermostat is probably not opening.
A second common cause of overheating is a leak in your vehicle’s cooling system. If your vehicle is loosing coolant there will not be enough left in the vehicle to keep it cool. This is easy to diagnose as the radiator will be low on fluid and there will probably be a pool of coolant on the floor of your garage. Look for leaks in the most common places like around hoses and around the welds of your radiator. If you can not find the leak you might need to take it to a shop to have the cooling system pressure tested.
