Patrick is very knowledgeable and takes his time to get the job done right!! I had 2 broken bolts in my exhaust manifold and he didnt give up or rush the job or tell me to take the job elsewhere to get it machined out.. (which would have cost me double the labor cost) Patrick was at my home from 7am and stayed until 2am to make sure my car was running and done perfectly!! As I had out of state company coming the next day. I will definitely use Patrick for all my future mechanic needs and Im so lucky to have found an honest, ethical and dependable mechanic/person. Its very rare these days!!

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.
