Three Reasons Why Your Car Keeps Overheating

You’ve got a big problem. Your car keeps overheating no matter how much you drive or what the weather is outside. You turn up the heater but this doesn’t solve the problem. This is because turning up the heater is only a temporary fix. If you keep driving an overheated engine, you’ll damage it. Cergizan’s Auto and Truck Repair explains below three reasons why your automobile keeps overheating.

1. Cooling System Problems

Let’s start with the coolant itself. If your engine coolant is old, it is likely dirty, and dirty coolant can deposit contaminants in the cooling system and clog it, especially the hoses. Once the cooling system is clogged by debris, the coolant can no longer circulate through the engine to reduce the temperature.

The wrong coolant – there are different types – or watered-down coolant is also problematic. It’s important to always use the engine coolant recommended by your vehicle’s manufacturer and ensure it’s diluted properly. Low coolant will also cause your engine to overheat constantly.

Other cooling system problems include leaks. The hoses can crack over time and leak coolant out of the system, as can the gaskets and seals. As the coolant leaks out of the system, the level gets lower and lower and your engine will steadily run hotter and hotter. It’s important to find the leak ASAP.

2. Radiator Problems

One area where you might have a coolant leak is out of the radiator. The radiator takes a lot of abuse from road debris. As it ages, it also begins to corrode on the bottom. Rust can form and eat through the bottom of the radiator, leaving you with a rust-filled fluid mess on your garage floor.

Corrosion can also clog the radiator and prevent coolant from circulating through the engine. Coolant is drawn out of the radiator and then returned to it once it has made its way completely through the engine. It rests in the radiator to be cooled by the radiator fan and air vents before it circulates again.

If the radiator fan is malfunctioning or the air vents are clogged, your engine will overheat because the coolant will not be reduced to a cooler temperature before it is circulated through the engine again. Radiator problems tend to occur more often on older automobiles, but they can affect any car.

3. Other Part Problems

Finally, let’s talk a bit about when coolant is released and how it makes its way through the engine. Two parts are responsible for this: the thermostat and water pump. The thermostat works kind of like your home’s AC and heater thermostat; it gauges the engine’s temperature and “turns on” the coolant.

When we say it turns on the coolant, we mean that it releases the coolant into the water pump so it can circulate it through the engine. The thermostat can malfunction and fail to release the coolant as the engine warms up. The water pump motor can die and become unable to circulate engine coolant.
