Tom is officially my new favorite mechanic. He came to do an oil change and tire rotation on my mother's car on a Saturday morning. He arrived at 11:00 on the dot ready to work. Very friendly guy, and we learned that he was a mechanic at Audi for about a decade. I love that he didn't talk down to my mother or me for being women, explained any issues we had and I could tell he really knew what he was doing. What a big difference from the last mechanic I had! Since the last mechanic that came left my car in a bit of a mess, I asked if Tom could take a quick look at mine as well once he was done. Being off the clock by then, he happily agreed to take a look. What an honest, great guy. On a Saturday, too! One quick look and he could tell the last mechanic didn't put my filter on right and that's why oil leaked everywhere..this is why it's important to look through reviews before booking your mechanic. I'll never use anyone but Tom! He's efficient, friendly, genuine and very good at what he does.

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.
