Do you do maintenance on 2001 GMC air conditioners (coolant refill)?
I recommend booking an appointment with me to inspect/diagnose of the A/C system to be sure that the issue is fixed correctly.
Do you offer any type of carbon cleaning services (walnut blasting, dry ice blasting, etc) for direct-injection engines with carbon build-up on the intake valves?
I don’t have the equipment for that service.
Do you do head gasket replacement?
No, that’s something I recommend getting done at a shop.
Don’t see your question? Ask away!
