How do you change a heater core in a 1981 Granada?
The best way is to do it the same as I did, cuss, moan, groan, take a mus. relaxer & pay someone else. But truthfully if you havw the time find where the 2 hoses go into the firewall for the coil & go from there it`s not easy & it`s very time consuming maybe even two days worth of work & a lot of tools but you can do it.
How do you replace the heater core on a 1991 C1500 Chevy pickup and does the Dash have to be completely removed?
To change the heater core on a Pontiac Aztek, locate the heater core on the firewall, passenger side of the vehicle. Remove bolts on the firewall and the clamps on the hoses. Take out the old heater core and replace with new. Tighten bolts and hose clamps. Then check to make sure the radiator is full of antifreeze.
