You probably do not hear much about the thermostat on your used car’s engine, but it turns out that it is a vital part of any automobile.
The thermostat is what regulates your engine’s temperature through the flow of antifreeze/coolant to the radiator. It is just a small part that is typically positioned between the engine and the radiator. When you start your used car, the engine begins warming up and the thermostat remains closed. Once the engine reaches a certain temperature, the thermostat opens and engine coolant begins flowing to the radiator to help prevent the engine from getting too hot.
Unfortunately, most people do not even think about the thermostat on their used cars until it malfunctions and causes damage to the engine. It is important to get the thermostat checked on a regular basis just to make sure it is in proper working condition. Some auto experts even suggest getting it changed every couple years simply to prevent any major problems. Since it is a small part and fairly inexpensive, this isn’t such a bad idea.
Bad thermostats can create a variety of problems that can lead to costly repairs. Malfunctioning thermostats can hurt your fuel economy, cause knocking in your engine and even cause your engine to overheat. If it overheats too much, you could blow a gasket and end up needing to replace the entire engine.
Keep an eye on the thermostat in your used cars. You don’t want to find out what this important car part does the hard way.
