Manuel was great. He has an appointment earlier in the day open up so he called to see if that would work for me -- which was greatly appreciated! He was very quick and incredibly professional.

Chris is very knowledgeable mechanically, professional, friendly and a Master Automotive Technician. He is also very courteous and a pleasant person to talk to. He changed my brakes and rotors and knew exactly what he was doing and did it quickly. He inspected my car and noticed other areas that should be addressed. I was so impressed with his professional skills that I had him book another appointment with me for next week to repair additional areas of concern I had bought the Lexus as a pre-owned car and saw the type of work the Lexus Technicians did vs the work that Chris did. Simple things such as lubing bolts before you put them on (which Lexus Technicians did not) or adjusting the parking brake which was not on the original order. I've always headed the saying that "It's up to you to choose what you do in life, but always strive to be the best at what you do." Chris has definitely done that.

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.
