Dave

Dave was on time and called to provide ETA before arrival. He diagnosed my engine vibration to a ignition coil and also low on oil. It's funny that he has to book himself via the app for the parts replacement to work within yourmechanic system. Picked up a new ignition coil and fixed my car on the same day and even went a step further to pick up a quart or oil and top off my low oil.

Robert

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!!

Timothy

Tim showed up early and had all the parts with him. He understood what was wrong and went right to work in inclimate weather. He got the job done in the right amount of time. He also went over the "bucket" list of things my car needed as I have a lot of deferred maintenance. He helped me pick out the most important things to take care of first as I have a limited amount of money

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.
