Chris was awesome. He arrived in time and didn't mind that I stood outside with him and watched. He had a great personality and great conversation. He answered all my questions about my car and about the company he works for. I have already given my family and friends his number and have told everyone I know about yourmechanic.com. I am very happy and satisfied with the service and also how easy it was to use the website.

Amazing. Prompt. Kept in contact (I was working, so he was talking to my boyfriend as well as keeping me updated via phone calls). Problems FIXED. Car running. Great price. Informed me of any and every change in the estimate. Honest and hard working. I would not (and will not) hesitate to hire Mark again. Absolutely perfect service.

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.
