Foam strips go on bottom and sides of heater core, right?

[thehackmechanic]

I'm reassembling my heater box. I didn't take enough photos when I disassembled it, and now my heater core is so clean that I can't see where the foam strips originally went. The FAQ says that the foam strips go bottom and sides of the heater core. But not on the top? Is this correct? This photo from Jim Gerock's disassembly sure seems to show the foam on the top. Or is the "top" the "bottom" as photographed?

I think there was crumbling foam on all sides of the heater core. Will have to go back and look at the ones I have in the garage.

Edit - the '69 heater core still has most of the foam sealing strips.

There are (2) thin strips that wrap around the perimeter of the core.

This is a thicker strip on the bottom lengthwise in a recess. I believe this seals the core to the bottom of the box.

There are (2) thin strips that wrap around the top (nearest the tubes) of the core.

Will take pictures tomorrow and post after site is fixed.

Thanks Jim!

Here are some pics of the old heater core removed from my 69.

Appears to have different types/sizes of foam strips:

1/4" Wide x 3/16" thick wrapped around both ends

1/2" Wide x ?"thick foam along the bottom where the core touches the box

3/4" wide x 1/8"thick along the front edges.

I've cleaned my core up a little so some of the foam has crumbled away - note the greenish areas.

Perfect. Thank you a second time!
