Awesome experience!! Chris was great!! I was extremely satisfied with his service. I would recommend him to family and friends. Besides delivering a new battery and installing it, He checked all the fluid levels, checked the tire pressure and made sure all the the malfunction lights went away. He was very professional, knowledgable and friendly.The final bill was less than I was quoted, because he gave me a $20.00 discount.I asked for his card so that I could request him if I need YourMechanic services again. Love this company!!!

All about Thermostat Replacement

A thermostat is part of the cooling system that regulates the temperature of the coolant in the engine. The thermostat is a metal valve that has a temperature sensor built in. It can either be open or closed. When the thermostat is closed, it keeps the coolant in the engine. When the engine gets to a predetermined temperature, the thermostat opens allowing coolant to circulate. The circulation of coolant prevents the engine from overheating. If the thermostat fails to open, the car will overheat. If the thermostat fails to close, the engine may never reach the optimal temperature (~220F). The thermostat opens and closes many times when the car engine is running. It is the most common component in the cooling system to fail, causing the car to overheat.
