Dave is the third person who has tried to diagnose the problem with my car and he fixed for about half of the original estimate in about half the time budgeted. I only hope that I'm able to get him again for ongoing service.

I was very pleased with Enriques service. He knows what he's doing, has a great attitude, and genuinely wants his customers to be well taken care of. He diagnosed my car and gave me a detailed explanation of what needed to be done and the most cost friendly way to do it. I will continue to use his services in the future.

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.
