Brandon was on time for our appointment and was very thorough in explaining the entire process. I like that pictures were taken of my vehicle before the service was rendered and he showed me the old part that was being replaced and the new part and explained why it needed to be replaced. I would definitely utilize Your Mechanic again and will request Brandon as my mechanic.

Rob was polite and professional, but relaxed and friendly. Told me about his experience and why he is working for Your Mechanic. Showed me how the brakepads are measured and showed me the worn grooves in the rotors. He was efficient and was a good sport about having to work in the sun on a hot day. Two thumbs up!!

G35s tend to be problematic for some mechanics when it comes to bleeding the cooling system but not for an expert like Norman. Feel at ease and very confident that my issue has been resolved. Looking forward to booking Norman for future repairs.

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.
