Jared was really personable and informative! He was running ahead of schedule so he contacted me to see if I would like him to come early. He not only took care of the known issue but was also thorough to find a secondary problem that I was unaware of. He made extra time for me to take care of both issues immediately! Great service and very competitive pricing will bring my business back whenever I should have need. Thanks!!!

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.
