Normally I do not confess to auto techs that I spent 40 years as a GM Service Manager and Service Advisor. BUT, Brikk was so pleasant and likable, our conversation was that of cars. He not only fixed my problem, but was sure to check other items on my car that I had not complained about. As I always tell everyone, there is but one thing that surpasses great customer service, and that is MORE of it...Thank you Brikk for a job well done, and if I ever need your service again, consider your phone ringing...Thanks

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.
