Chris was a pleasure to work with. He had the tools and ability to R&R my Crankshaft & Camshaft Position Sensors without dropping the screw so he was able to get the job done quickly. It looks like I've found myself a new mechanic to work on my car's engine when it's cool . Thanks Chris.

Dave arrived on-time. In replacing the front brake pads, he was highly efficient (fast) in completing the job. He shown me the brake pad senor indicating there is only 1, not a pair of them. That fact saved me a few dollars on the bills.

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.
