Jeff my mechanic was fantastic and the car is running very well now. The yourmechanic.com service was a bit suspect. Not sure they have all the website/customer service kinks worked out yet but, Jeff overcame the obstacles quickly and with a great attitude. The website service did not understand what parts I needed (and its simple really, as it was just motor mounts). I suspected this and called to confirm and was told they would make sure the mechanic would have what he needed. He did not, it delayed the repair time and changed the price.

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.
