I have a harrison radiator that was in my 67 firebird. Codes are
tk
oe
55 with a MZ sideways next to these numbers. OE is in the right tank by the tag.
Part # looks to be 3010276 8 It is just under 3" thick. I think it is a four core.
I can't find any info anywhere on the web!
Any help??? Thanks!!Tyson

Look down in side the filler and count the cores. If you take it to get it recored or replaced make sure you keep the tags. Sometimes they can be worth more than the rad itself.

I will have to get it dug back out and take a look.
It doesn't leak, so not sure if I want to get it rebuilt. It was rattle canned black at one time and a couple of the fins are bent, but over all it is in good shape. Car it came out of hasn't been on the road in probably 30 years. No ideas of how I can find info on what it came out of??
Thanks

Look for an aluminum tag crimped onto the right side tank. The other numbers are not in the parts book.

I've collected a lot of rad codes over the years and I have not run across either of those tank codes or the rad code.
