Changing a thermostat in a car is the process of replacing the device that regulates the engine’s temperature. The thermostat is responsible for opening and closing to allow coolant to flow through the engine, keeping it at an optimal operating temperature. A faulty thermostat can lead to overheating or underheating of the engine, which can cause serious damage.
Replacing a thermostat is a relatively simple and inexpensive repair that can be done in about an hour. It is important to consult your vehicle’s service manual before attempting this repair, as the location and type of thermostat may vary depending on the make and model of your car.
