I would happily and with great confidence recommend Mark. But as a service, I"m not sure. My first experience was not great. I had to have a warranty appt due to the first mechanic's faulty work. I had issues w/ my car after the first mechanic completed work. Mark- second mechanic had to correct errors and provided a thourough explanation of my vehicles performance. I would book Mark again for all and any service.

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.
