Re: Removing old heater core (Wrencher)
Cool I was hoping this could be done this way. I posted about my core going out and this looked very doable from the engine side. Thanks for the pics. I'll be ordering a core shortly. :yesnod:

Yes, the clip is a snap fit on the outer housing box (to the left in the pic) and simply pushed against the edge of the core. Believe it or not that is all that holds that core in.

Just got mine out. 1/2 hour to remove the heater core. New one should be here in a day or two. 31 dollars from a local supplier. Better than 60 from Zip. Just hope it is the right one!

FYI. I had to move the website with the heater core pictures from annapolis to the forum website. (I blew my space limit). This is for a car with AC.

Re: Removing old heater core (Bob Demmel)
"WHen I removed mine on a '71 with A/C, I only removed the front panel on the dash on the passenger side. THe rest was pretty straight forward. You just have to take your time and make sure you find all the bolts holding it in. SOme are covered with a tar or caulk like goop. It took me about 8 hours working on it at my father's car repair shop."

Ditto. The job on my '71 with A/C was not hard, just time consuming (~6 hrs.). I only removed the passenger side of the dash.

Re: Removing old heater core (SharkAttack)
Houston, we had a problem. On my 74 w/o AC, removal and repair went great working only from the engine side. Just as described, the heater core came out with only a little encouragement and was out and ready for repair in much less than an hour. Then came re-assembly... if I hadn't seen the core come out I would have sworn it was too big to slip back into the housing. After an hour or so of trying to find out what was stopping it from going back into the housing, I quit (thinking some "sleep-thinking" and a beer might help). The next day brought an improved attiitude but little success. By this time I even had out the 2x4. I decided to go back and re-read the posts on the Forum. Thanks to Paul79's pics, I saw that he had installed the foam gasket into the housing and then fished the heater core tubes out through the gasket. AMAZING! I had the core in place within 5 minutes. DO NOT put the foam gasket onto the heater core and then try to put them into the housing as an assembly. I can't believe something so simple could cause so much trouble. Thanks Paul79!!! I couldn't have done it without your pics.

P.S. 3M Ribbon Sealer p/n08610 (ribbon caulk for windshields) is a great replacement for the "black goop". :D
