Enrique is very professional, courteous, and thorough. He was fully prepared and equipped for the job, and was very well organized. He performed the work in a timely manner. A more serious, deeper problem within the engine remained after he was done, and will require significantly heavier maintenance which is beyond the scope of this company and service. Nevertheless, I highly recommend Enrique, and will use him and YourMechanic again in the future, if I have other maintenance needs on this car or my other car. He is a good man.

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.
