[24seven]

Hello Folks,

Anyone have tips for replacing the heater core

in my 1976 Riviera. I have a service manual,but it

seems vague.Thanks in advance for any and all replies. HenryJ SoCal 1976 S/R ROA 11572

OK Folks,

I got it. Seems I failed to remove two bolts from under the hood. There should be a total of five from under the hood; one top left and two together directly across to the right and two more directly below those.(Asyou face the windshield)

Also noted that I had a vacuum line connected to one of the threads so I didn't know it existed. Inside I removed the glove box and liner and assorted ducting/vacuum lines/ control cable and the heater box unit was coaxed out from underneath the dash. Inside there is also a metal bracket(two bolts) which braces the unit(it comes out with it as well) and two more bolts on the heater box that make this happen. Now to put it back together. Hope this helps or amuses someone.

Thanks, Henry SoCal 1976 S/R ROA
