Thanks again for a flawless repair without the hassle of waiting at the maintenance shop. Justin arrived with motivation and enthusiasm. He discussed that he would drain the engine coolant to replace the thermostat. He instantaneously started working on the vehicle and completed the work on schedule. Justin cordially performed final inspection to ensure engine light was off. He provided receipt via email. The media was very informative in that it had a voice notes explaining reasons for visit, problems found, and service provided. Justin is a pro who goes above and beyond.

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.
