Has the car thermostat gone bad? Here’s how to replace it

Much like a thermostat that controls the temperature in your home, a car thermostat helps control the temperature of your car’s engine. Without it, your car may not heat up properly or it will overheat. It’s an inexpensive part, but if it gets worse, it can cause expensive problems for your car.

A car thermostat is a spring-loaded valve located between the engine and the radiator. It shuts off when the engine is cold, which allows the car to warm up faster. Once the vehicle reaches operating temperature, the thermostat opens and allows coolant to circulate through the radiator to cool.
