Coolant Thermostat Repair

Even though today’s engines are highly advanced and computer controlled, there is still one thing that decides if your car is going to run properly or not. Your car’s thermostat regulates the amount of coolant that flows through the end. This coolant is needed to keep engine temperatures low and to keep your car operating smoothly. When your thermostat fails, your car’s engine temperatures will rise as you will see your dash gauge indicate and you may eventually see steam coming from under your hood. Finally, your car will shut off and leave you stranded on the side of the road.

If any of these symptoms occur, it’s very important that you bring your car into GIC Car Clinic in San Jose, California right away to have it checked out by one of our trained, knowledgeable technicians.

How Does My Car’s Thermostat Work?

Your car’s thermostat does two very important things: it helps your car warm up faster to ensure optimum efficiency and it also protects your car’s engine from overheating which could lead to poor drivability and engine failure. By regulating the amount of coolant that passes in and out of the engine and through your car’s radiator, the thermostat provides a very important function to the longevity of your car.

Basically, the thermostat is a spring loaded valve that is normally held in the shut position. This ensures that the coolant travels through the engine and allows it to warm up quickly. When a preset temperature is reached, wax inside the thermostat melts and begins to expand pushing the valve open and allowing the coolant to flow out of the engine and through the radiator to cool it down. The coolant then travels back into the engine to provide cooling and reduce engine temperatures keeping them at a safe level.

When the wax element cools down, it contracts and the thermostat will begin to close partially. This open and shut cycling is what helps keep the engine at a constant temperature and you driving down the road.

What Could Cause My Thermostat to Fail?

There are many things that can cause your car’s thermostat to fail; from overheating, corrosion or age, the thermostat will stick in the shut position. The thermostat can also become stuck open due to a binding element, broken return spring or a piece of debris jamming the spring mechanism.

My Thermostat Failed, Now What?

If you ever experience a failed thermostat, you should have your car looked at right away by a trained professional. When your thermostat fails to open, coolant will not be able to flow out of the engine and cool down in the radiator; this will cause your engine to overheat and stall. If your thermostat becomes stuck open, it will not allow the engine to stay at the proper operating temperature and it will increase fuel consumption and offer very little heat to the passenger compartment.
