The mechanics themselves are great. But the Your Mechanic business side of things wasn't at their level. The initial diagnostic said I should replace an O2 sensor. I scheduled the appointment to have it replaced. Two days prior to the appointment, 'your mechanic' called and said the initial quote was wrong and that I needed a different O2 sensor which was more expensive. I OKed the different part and when the mechanic showed up, it turned out to be the wrong part for the car and the mechanic said I needed the sensor which was originally recommended. This caused a completely unnecessary delay and multiple appointments which didn't need to happen. I asked the customer service rep why they changed the part recommendation in the first place, and he didn't really have an answer for me. I can't help but think it was an attempt to up-sell me. They did compensate my trouble by throwing in a belt replacement for free and said they gave me another discount as well. So I appreciate that. But in terms of trust and reliability of the business, I'm going to have a hard time vouching for this service as the convenience factor was clearly compromised.

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 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.
