David was on time, extremely professional and polite. The service (brake pads changed) I had scheduled was more than I needed and David saw to it that I was only charged for the work he performed; I was quoted to have all the pads changed but only need the back set done. Definitely happy with the service he provided and will certainly use this service again for my future car needs. It was refreshing to deal with a mechanic that wasn't out to take my money for services I really didn't need; this was the first time i didn't feel taken advantage of when it came to servicing my car.

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.
