Brikk was great. We asked him to change out the alternator on my sons Saab based on a noise he was hearing and also from a garage he took it to. They said the noise was the alternator and it was about to go. He did not get it done at that garage because they want over $800. Brikk listened for the noise but was not convinced it was the alternator. He said it was putting out what it was supposed to. Unfortunately on that day we were not able to produce the noise so Brikk said to contact him when its making the noise again because he would like to be sure. I don't think the noise has come back so far. Its my sons car so I have never heard it. So we are kinda waiting to see what happens but Brikk was great, informative. I like this service very much so far in the few time we have used it.

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.
