Lucas

(see previous review) Lucas came back to my house to re-replace a part: he discovered a more updated version of the ignition coil existed. He arrived early, replaced the part quickly, and gave me a verbal run-down of all of the work done on my car (and what to expect into the future). Officially making him my personal mechanic from here on out!

David was great and we were very happy with his service. He showed up 15 minutes early which was very impressive. Was clean and thorough and explained everything in detail. I will definitely have some other services done on our cars and will request David do the work.

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.
