1990 GMC Sierra 6 cyl Two Wheel Drive Manual 77000 miles
I need to replace the heater core. I cannot find sufficent information for removal and replacement of the core and the plastic box it is contained in. Where are the screws located in the engine compartment? I have already removed the windshield washer reservoir and heater hoses and the glove compartment box. Does a picture of the removal procedure exist? Here are 3 pictures of the truck.Thanks for any information you may be able to help me with.
