Dave showed up at the exact time and finished the complicated job in 2.5 hours. The coolant had to be emptied in order to fix the issue. He topped it up and warned me that it might need a little bit more water after driving a few miles. The coolant warning did come up and I topped it up and no more issues since then. The buggy temperature level / thermostat/check engine is no longer a problem and I should be able to pass smog now.

Augie's service was great . He arrived on Time and did a Oil Change for my Audi A6 vehicle. Apart from the Oil Change he was kind enough to look around the vehicle and show me what other things I need to take care like Oil Leak, Gas Cap etc. I am pretty impressed with the service provided by Augie and would highly recommend Augie Morales. Thanks

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.
