Question

I have to pull out the heater core in my '69! I noticed it had blown, and I spent the day yesterday cleaning up my interior!

Is there anything special I should be concerned about when I do it?? I have done them before, just not on this car. What type if sealant should I use when I re-install it? It looks like silicone on there now.
Also, what, if any, troubles should I anticipate??

Your help is greatly appreciated!

Assuming you have a non-A/C car and a small block there's couple things I learned that may help you when I did mine a couple months ago.

There are 5 studs on the inner heater box that go through the fire wall, through the outer box, and tighten with nuts in the engine compartment. The outer box has two additional sheetmetal screws above and below the blower motor inside the fender. (7/16" heads on them if they're original)

The tubes on the end of the heater core are difficult, and on some cars (mine is one), impossible to get through without bending. If this is the case the outer box needs to be completely loosened and slid toward the fender to gain clearance. I would avoid bending these tubes because . . . the solder joint at the end of the tubes can crack and leak on you - then you wind up doing the job again.

It's not that bad of a job, you just need a little patience. Good luck!

Monte,

This has been discussed many times. Use the search function and you will be amazed at what you find. You can try searching in other forums too. I think someone even made a post requesting tips that got a lot of responses.

You will have to remove the passenger side fender on a '69 to get the nuts off around the heater blower motor. Put masking tape on the edges of the door and fender, so you don't scratch them when putting it back together. Good Luck!

BTW I got the bolts by the blower motor out of my 68 without removing the fender, so it can be done (I think a 69 would be the same). A nut driver and some grease on my arm and I got the top one. The bottom one I drilled a 3/4" hole in the inner fender well and got it with a socket and wratchet.

BTW There's not much in the archives about these screws and the outer box. I looked when I did mine.
