What Problems Does a Faulty Thermostat Cause?

A faulty thermostat can cause numerous problems in your car’s engine. CAR FIX in Cookeville is going to list those problems below. If your car is younger than 10 years old, you shouldn’t have any problems with the thermostat. This cooling system part generally lasts a decade. If you drive an older automobile, however, you might begin to have problems with your thermostat, especially if you notice any of the following issues. Don’t worry. We can replace your thermostat when it needs it.

Corroded Thermostat

One of the first signs that your thermostat needs to be replaced is corrosion. In order to release coolant into the engine, the thermostat opens and closes a valve. If this valve gets stuck in the closed position, the coolant will pool around the thermostat and the thermostat housing. Consequently, this will corrode the thermostat and the thermostat housing. This corrosion can affect the thermostat’s functionality, so it’s important to replace the thermostat if it is corroded.

Leaking Engine Coolant

The thermostat is not only leak minorly; it can also leak coolant onto your garage floor. It’s important if you see puddles or spots of coolant that you avoid driving your automobile. As the coolant continues to leak out of the engine, the levels will get too low, and your engine will overheat. We will talk more about that below. Coolant can leak from the thermostat, and it could also leak from the water pump, the radiator, the radiator hoses, the cooling system seals, and the cooling system gaskets.

Odd Temperature Changes

Leaks aside, your thermostat may also start to malfunction if it is over 10 years old. If you keep an eye on the temperature gauge on your dashboard, you will be able to see the thermostat malfunctioning. You will notice that the needle goes up and down erratically as the thermostat opens and closes the coolant valve. The problem is that the thermostat is not opening and closing the valve at the right time. Consequently, your vehicle will go from cold to hot and back to cold again frequently.

Overheating Engine

Finally, as we mentioned above, a leaking thermostat can make your engine overheat. A malfunctioning thermostat can also make your engine overheat if it doesn’t release enough coolant into the engine. Finally, if the thermostat is dead, it won’t release coolant into the engine at all.
