I was hesitant to use a mobile service, but my disability makes it difficult to keep my car maintained. Carlos was professional, competent and reassuring. He arrived at the scheduled time, and I received updates by email as well. He put a barrier down to ensure no oil spilled on my driveway, and showed me some features on the car I was unaware of! He never tried to "upsell" me, which has happened at the mechanic's before. I am very pleased and will use the service again.

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.
