Trung

Trung called 20 minutes before appointment to let me know he would be arriving in 10 minutes which I thought was great. When he arrived he appeared very professional and explained to me all the services that would be performed on my vehicle. So I left him the keyes, went back into my office and 45 minutes later he called to let me know my vehicle was done. When I came out he showed me that my air filter was extremely dirty and offered to run to the parts store and pick one up and it would only cost me the $23.00 additional for the filter. I absolutely thought this was tremendous service. Trung went far beyond any expectations I had for a mobile mechanic service and I will surely be recommending Trung and Yourmechanic to all my friends and family. Thank you Trung for the great service and thank you Yourmechanic!

This was my first time using YourMechanic so I wasn't sure what to expect. Noe showed up early like a true professional. He gave me a time estimate of an hour to hour and half - and ended up finishing in less than an hour! Also, the actual total was considerably less than the initial quote. He exceeded my expectations and I highly recommend Noe to anyone who wants above and beyond service.

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.
