Excellent. Rick showed up early and was very friendly and courteous. He was not aggressive in upselling me on additional services which is important to me. He only made recommendations which were actually crucial. He set an appointment for me but told me it was optional and that I could cancel, which I did due to financial restraints at the moment, but I will be booking with him in the near future for the recommended services.

All about Car 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.
