I own Dublin Auto Repair in Dublin, CA and Milt's Service Garage in Vallejo, CA. Both ASE Certified facilities have ASE Master Technicians that perform general repairs on all makes and models. For piece of mind you have a 12 month/12K mile warranty on all repairs we complete. We also have a racing arm known MServiceGarage. We service those individuals that track/autocross their cars. The knoowledge we've gained is yours when you commission us to build or consult on your race car. Remember that second place is the first loser...(just kidding)
My philosophy is very simple: Provide our customers with the best solution to the problem presented! We diagnose the failure and determine what type of repair is needed to get that vehicle back on the road. We provide one year warranties, towing, shuttle service and no interest financing. Maintenance costs far less than a repair so we perform a free courtesy inspection on every vehicle we see so our customers can remain informed.
Check coolant level first and top off if necessary. Your thermostat cold be stuck open if the coolant won't reach 190 degrees but you temp sensor could also be defective. Instead of throwing parts at it you should let a shop properly diag and make the repair. It will be cheaper in the long run.
