Do not archive.
Just thought I'd mention that I removed my first
A/C core from an '82 Chev'y sedan in my local junk yard.
Took me 2 hours to remove lots of OTHER stuff before could lift it out of
plastic housing. Paid $10 - was in perfect shape (haven't leak
checked).
It was a somewhat different length-width from
what Rino (?) posted in a diagram some time ago (93 Chevy Van core?). Mine
was 10 3/4 inches across end caps instead of 13 1/2 & was 7
3/4 inches not couning end caps instead of 10.5; mine was 10
1/8 inches high the other way (instead of 8 3/4), and 3 5/8
inches thick (same).
So, my sfc area is just 4.1 sq inches less than
Rino's. My volume, not counting end caps, is 284.4 cubic
inches (394.6 counting end caps, vs 333.0 for Rinos w/o end caps).
Looks like GM/Harrison made these things in a
variety of sizes (ht & width) with thickness about the same, and total area
and volume close to the same..
Getting the plastic upper housing off was biggest
challenge: Had to remove fan and lay aside, then remove windshield chrome
trim at bottom of windshield, then remove 2 or 3 steel brackes for that trim
piece, all to be able to lift plastic housing almost straight up.
Tools: 1/4" socket (for lots of plastic
housing and windshield trim stuff)
10mm for a number of larger screws holding plastic top
housing to firewall, as well as a few other things.
Other sockets (5/16 and some other std larger &
smaller)
Hacksaw for aluminum tubes when couldn't break loose the big
3/4 and bigger nuts on freon tubing
Core just lifted straight up and
out.
