What Causes an Engine to Overheat All the Time?

You cannot afford to have your engine overheat every time you drive your car, truck, or utility vehicle. If you drive the automobile when the engine is too hot, you run the risk of causing serious damage such as cracking the engine block. Premier Auto Repair is going to list the common causes of an overheating engine below. Bring your vehicle to our shop as soon as possible if it has an overheating problem.

Poor Coolant Circulation

Your engine will overheat if there is no coolant circulating through it. The water pump is responsible for the coolant’s circulation. If the water pump is going bad, which can happen after 100,000 miles, it’s possible that the engine is overheating because it does not have enough coolant circulating through it.

Leaking Cooling System

A leaking cooling system will also cause the engine to overheat because the coolant levels will be too low. Coolant can leak out of the radiator, the radiator hoses, the seals and gaskets, the water pump, and the thermostat among other cooling system parts.

Clogged Cooling System

The radiator hoses might also be clogged with debris and this will prevent the circulation of coolant through the engine. The radiator can also become corroded and clogged if you drive an automobile that has a ton of miles on it.

Malfunctioning Thermostat

If the thermostat is malfunctioning, it may not release coolant into the engine. This, naturally, will make the engine overheat. The thermostat lasts on average about a decade. This being said, a malfunctioning thermostat could be the cause of your engine’s overheating problem.

Radiator Damage/Problems

As we said above, the radiator can get clogged over time. It can also get corroded and leak. The radiator air inlets can get clogged and this will prevent the engine coolant from cooling down. You might also have a problem with the radiator fan.

Overdue Maintenance

Overdue maintenance, especially oil changes, can make your engine run too hot. You need to make sure that you stick to your service schedule to ensure that your engine always runs efficiently and at the right temperature.

Malfunctioning Fuel Pump

A malfunctioning fuel pump can also cause the engine to overheat all the time. If the fuel pump motor is overheating, your engine will overheat.

Clogged Catalytic Converter

Finally, a clogged catalytic converter will malfunction and generate too much heat underneath your automobile. When this happens, the heat finds its way into the engine and causes it to run too hot.
