Patrick

Patrick was both professional and friendly, willingly chatting it up with me about my car. He lowered my estimate because the job was slightly less than what the website quoted, which was nice. While my mount was described as "broken" by another mechanic, he mentioned it was merely cracked and it was up to me if I wanted to get it replaced, which I did anyway because eventually the cracking would lead to a breakage. It was definitely a pleasure to be able to see and talk to the mechanic who was working on my car vs oftentimes where you just talk to the front man of the shop. I would fully recommend Patrick to anyone who needs work on their car and I will go back to him for any work more than an oil change.

Blake was very professional, polite and courteous. He showed up on time to the 2 appointments that I had and completed the 2 fixes that I had on my Mazda6 (power window was not working and the door lock was not working). My only constructive piece of criticism was the actual price of the job was a bit higher than was quoted to me online. I believe it took him much longer to complete the job than was originally anticipated. I plan on using this service again.

All about Car 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.
