Default Help Any tips on changing Heater Core

My Dad has a 94 c4 and his heater core went out. Does any body have any tips or help files on changing the heater core.

Thanks

I can't help with the repair, but its a good policy to buy a Helms manual.

The consensus is get new heater hoses, and a GM replacement core. Many post of Napa or Auto Zone units not fitting properly, do a search on heater core, there was a run on them on C4's about 2-3 months ago.

Move everything away from around your car that flying tools may damage.

Take your time, take almost all of the dash out that you can, especially the right side, and be patient. It was a religious experience for me. Took all day just to get to it.

Re-read Renoman's and BILLSF's answers, they speak the truth. I did mine on my 85, that's how I got my avatar but the 85 is different than yours. Justardnck did his, maybe he will chime in here or you can email him for advise.

Thanks for everybody's response. We have a factory manual to help use out. My only concern really is how do you disable the air bag?

Check your fuse block, and remove all fuses that say air bag.

So if I remove all the fuses it will not go off?
