Rodney went above and beyond working on our 1993 Buick LeSabre. The auto had a start run briefly then stop and would not restart. Rodney replaced the suspected (code 18) part crankshaft positioning sensor, the crank pulley. Auto does not even start now. There could be other potential issues as is the case with the early mid 90's GM autos. There could be other suspected other parts and issues here. Though I do believe that your mechanic should send someone to further investigate this problem at no charge, after all the car did start now it does not!

Great experience. I had ordered the wrong part originally (the Buick engine is crazy, what I thought was the front was actually the side. Go figure. That's why my battery is under the passenger seat in the back.) Anyway, Ben rescheduled the appt and he called me to let me know that he had the correct parts. He showed up on time (a little early) at my work-site. He is very professional and took the time to show me the malfunctioned parts. The quote was perfect. I had checked at a couple of garages beforehand and the price was a couple of hundred higher. I need a couple of other things done and will defiantly be scheduling with Ben again!!

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.
