Dan showed up on time and was very prompt and courteous. He even called once the service was completed and explained to me that the brakes had only about 10,000 miles left on them. Very convenient to have him come to my place and work perform the service while i was at work.

Zachary

Zachary is an excellent mechanic! He arrived a little early for our appointment. He carefully evaluated and diagnosed the problems with my GMC Envoy overheating - It needs a new serpentine belt and drive belt tensioner. We had two previous mechanics who could not figure this out, so we really appreciate Zachary. He answered all our questions completely and made sure we understood everything. We're looking forward to working with Zachary again, and highly recommend him to everyone!

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.
