After moving to a new city I needed a new mechanic. I was set up with Steven who came to a dealership to meet me and inspect a used Mercades I was interested in. He was very genuine about his review of the car along with being highly experienced. It seemed like he truly cared about me and my purchase unlike past experiences. Steven was just an overall nice guy who I knew I could trust off the bat and I will continue to use him from YourMechanic in the future. Thanks for making this completely hassle free and providing a great report of my new cars health.

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.
