I have a 1996 Chevy Blazer that needs the heater core replaced. We have bypassed it temporarily. Our dexcool system was a nightmare. Gummed up and clogged the entire system. We have since done a complete pressure flush and cleaning through the dealership and replaced with regular antifreeze. (That was a $600 pain in the pocketbook) However, now our heater core has taken a dive. They want another $700 to replace that. We have decided to attempt this on our own. We have not worked on this vehicle yet, but did many repairs on our old 1992 GMC Jimmy. Does anyone have any hints, help, gripes or good cusswords to use for this job?
