This was my first time using YourMechanic and I was very satisfied. I found the quote quite reasonable. Dave was able to fix my issue on the spot within a half hour without having to order a part. He also recommended where I can find cheap parts. Since I didn't have to order a part I was given credit back to my account! I was very pleased :)

Chris is by far one of the best and honest mechanics I've ever dealt with. My car is older and rusted so the amount of time he spent to do the work and explain what he did was awesome. I highly recommend Chris and his services!!!

All about Car 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.
