My first time using this service and it was great. I have a very busy schedule so taking my car into the show is a hassle. Patrick provided Excellent service with good advice about my car. He was early and the prices are cheaper than an auto shop. Will use Patrick and this service again.

Tom is a very good mechanic Wish there would be more people around like him. He fixed the problem in a very short time. I had this problem before and it took the Pontiac Dealer 4 month to fix it not to mention the cost. Thanks again Tom. Regards Juergen Westerwelle

Jose was very professional, was on time (actually a bit earlier than expected which was just fine for me) and did the job in a timely fashion. There was a mix up with the part but he went out and was able to get the correct one, at no extra charge for me, and he even made sure that everything was working afterwards. Did a great job and would definitely recommend to friends and family.

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.
