If only all interactions with mechanics were as pleasant as with Josh. Josh is professional, knowledgeable, detail oriented, and easy to communicate with via texts and calls. His passion and love for his work is obvious. It's a wonderful thing to see. When my car needs servicing again, I will be sure to schedule another appointment with Josh. Highly recommend.

5 stars for Chris! He performed a pre-purchase inspection for me, and was super informative. After reviewing the report, I both called and texted him multiple times for additional questions. Each time he was extremely friendly, courteous, and knowledgeable. I hope to hire Chris again 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.
