First time jitters (risk vs. reward) with YourMechanic. Well worth it after the experience working with Jason. Solely because of the overall pleasant and professional experience with him would I try YourMechanic again. He did a thorough test and review of the auto shop that had diagnosed a fault and cut down my cost by negating one of the things the shop had recommended to do. He provided relevant information about the repair and the underlying system, which put me at ease about his knowledge. He is really diligent and follows up as promised. Thank you Jason - as you can imagine I hope not to see you soon, but in case I need to then you will be my first choice :)

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.
