What We Do
Bring your GMC truck to PowerFlo if you are experiencing any of the following diesel engine issues: starting or stalling problems, a surge when you’re idling, engine knocking, insufficient power and the appearance of black, white or blue smoke. These may indicate problems with your high-pressure pump, fuel supply system, turbocharger or exhaust gas recirculation (EGR) system. After making a definitive diagnosis, we recommend a solution, and then once we get your approval, our mechanics expertly perform the repair.
In addition to engine service and repairs, turbocharge upgrades, custom tunings, we perform scheduled maintenance, repair and upgrades of your vehicle’s:
