any tips of ease replacing the heater core on a 1991 full size blazer
Well it's not rocket science but it could be a sticky mess. Do it on a weekend if your going to give it a try ( Give yourself time to pick up parts) I don't have the time to go through the process but a Haynes book on your vehic.le would be a worth while purchase. Drive On
Ive done it on a 94 c3500 without removing the dash but it was a tight fit. I belive it has the same dash as yours.
