Why Does My Car Overheat?

Cars can overheat for a number of reasons, all of which are easy to identify and treat. In order to help you prevent your car from overheating, and in order to help you maintain a safe and fully functioning vehicle, we’ve put together a list of the most common reasons for overheating. As you read on, please note that even the most knowledgeable drivers—those who know their way around engines—will call a professional if they notice two unmistakable signs of overheating—some pouring from under the hood or a foul smell from the engine.

OK, so why does your car overheat? Here are the top five reasons:

·       A Stuck Thermostat: A stuck thermostat will block coolant from reaching its destination—the engine.

·       A Leak in Your Cooling System: A leak in your cooling system will prevent coolant from reaching the engine. When this happens, it is often the case that the source of the leak is in your radiator’s welds or in your hoses.

·       Water Pump Malfunction: The water pump is the most important component of a vehicle’s cooling system, for it circulates coolant throughout your engine. A vehicle whose water pump is not functioning properly will overheat within minutes.

·       Jammed Radiator: Your radiator is a magnet for all manner of debris, which, left unattended, will cause the radiator to jam or clog. The best way to prevent this from happening is to regularly change the radiator fluid.

·       Malfunctioning Fan: If your fan—and most cars now feature electric fans—does not start functioning as soon as your vehicle reaches the right temperature, have it replaced immediately. Often, the reason behind a malfunctioning fan is a leaking fan clutch.

The best way to prevent your car from overheating is to schedule regular maintenance and check-up appointments.
