Originally, I was scheduled to work with another mechanic, who is no longer available with YourMechanic. I was told that Josh would be taking over the work on my Mercedes, but that I would have to wait a week for his next available appointment. My first experience with Josh was a very positive one. He is very professional, upbeat and friendly. He arrived early, explained the issue at hand very well and was very clear and concise about next steps. He found that my original mechanic only found part of the problem with my car, not the whole issue. So he comped the labor and parts from his visit and scheduled a follow up appointment with me to install the final part and complete the job. Thank you very much, Josh!

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.
