4 Common Reasons Why Cars Overheat

Blog

An overheating engine is one of the biggest problems that your car might have. When you allow the engine to overheat, the components will start warping and cracking. With time, the damage might become irreparable, and you might have to replace the entire unit. It is advisable to always look out for signs of engine trouble and visit the auto repair for immediate repairs. Here are four of the most common reasons why your car's engine might overheat. 

Low Coolant Levels 

The cooling system allows your car to eliminate most of the heat that the engine produces. The coolant absorbs the heat and moves to the radiator, where the cooling process completes. Once the coolant has lost the heat, it circles back to the engine. Therefore, you need healthy coolant levels for the cooling process to run smoothly. If the coolant levels drop below the recommended levels, your engine might start overheating. The auto mechanic will fix this problem by simply topping up your coolant levels. They could also check for signs of a leak in the system and seal it. 

Problems With the Thermostat

The thermostat is also part of the engine and car's overall cooling process. When the engine is starting, its thermostat valve stays closed, and the coolant does not circulate. However, when the engine heats up to its operating temperature, the valve opens, and coolant starts flowing through it. If the thermostat is faulty, it will not prompt the valve to open when the engine gets hot. When the coolant doesn't circulate, the engine will overheat. The best way to handle this problem is by repairing or replacing the faulty thermostat. 

Damages to the Radiator and Cap

The radiator is where the heated coolant goes to lose the heat. The radiator design comprises tubes that have fins in them. The coolant moves through the pipes, and the fins collect the heat, lowering the coolant temperature. If your radiator gets damaged in an accident, the cooling process will not work. Similarly, if the cap gets ruined, your coolant will boil off and escape, leaving your engine hot.

Issues With the Radiator Fan

The air flowing inside the radiator removes heat from the coolant. When the fan is damaged, it can't blow cool air over the coolant. Consequently, your engine starts overheating. 

The auto mechanic will help you figure out the cause of engine overheating on your vehicle. With their help, you can diagnose and correct the issue, saving your engine from complete damage.
