i was looking at fan shroud and noticed it had been cut just a bit.the radiator has brand name HARRISON.does anybody know if this is original to 1967 firebird?

Wanna sell it?

This my orginal heater core.

Original radiator is Harrison too. Does it still have the aluminum tag on the frame?

yes vicki it does have a thin tag sticking out toward the top but cant make out all numbers.thanks for picture norway.catalina by the time i get the dong gone bumper off ill be ready to sell whole [censored] thing LOL.

Harrison were original equipment. Depending what you 'bird was equipped with it would get a 2, 3 or 4 core Harrison.

I did some # checking and found I have the original 3 core for my convertible. It's now in my cammer when I upgraded to a Desert Cooler 4 core for my drop top.

oops i didnt think that was a bad word sorry.

Your radiator tag should have two fairly large letters stamped in. But just the presence of a tag makes it likely that the radiator is the unrebuilt original.

Sorry to say that after 40 years, it probably has some "hardening of the cores". It may not be in prime operating condition any more. I just had mine recored, retaining the original tanks, which will restore it to full performance while retaining complete originality.

Hey Vikki, how much did you pay to have yours recored? I recored mine a couple of years ago. I can't recall the exact figure right now, but it seems like I paid around $300 for a four core--which I thought seemed kind of steep at the time. Just thought I'd ask, I've always wondered if I paid too much. My car runs cool as a cucumber though. No overheating problems whatsoever.

I don't have the receipt in front of me, but it was about $325 from Superior Radiator. Also four core. With the price of copper that is a reasonable price.

Back in the '80s I had a 3 core wide radiator recored for $125, so it was a bit of sticker shock when I got the quote. But I am very happy with its perfectly original appearance.

Thanks Vikki, It sounds like the price was in line. I'm happy with the appearance and performance of mine as well.

I did the same thing Vikki did, had my original recored retaining the original Harrison tanks. The radiator appeared to have never been out before until earlier this year. Only problem was the top brace of the new core was a bit narrower and my original power steering cooler line clips didn't fit snugly like they should, but still worked out ok. I paid $253 out the door.

vicki the letters on it our 66-036 3R10187 did you send off radiator to get fixed or is that place local to you?

They are local to me, they're a national radiator supplier but I am sure you can find a local radiator shop, it will save a lot on shipping.

The code tag should look like this: http://forums.performanceyears.com/forums/attachment.php?attachmentid=81035&d=1170156899

I too had my Harrison rebuilt with a four core, $315.00 I still have the tag on it. Cools beautifully even in 100 degree weather.

Where on the radiator is the tag supposed to be found? Mine says "Harrison" on it on the passenger side tank near the top, but I can't find a tag. Maybe didn't survive the last 41 years.

That's not unusual for the tag to be missing, especially if the radiator was ever removed for recore. It's clipped to the engine side of the passenger side tank, alongside where the trans cooler ports would be if for an automatic.

It's really not all that unusual to find an original radiator in an unmolested car. It's just that quite often they don't function as well as they should due to internal or external corrosion or clogging.

Anybody know where I can find a listing for the letter codes on the side tanks as far as application goes?

All on my site, by year.

Vikki,
The data you posted is pretty good, but it's probably not completely correct. I've seen some sources with different codes for some of those Firebird applications. There are often discrepancies between the service and the production parts. And I've never seen GM use the same part for auto and manual back then (like the 69 L6's above).
It's really hard to find docs on the original configurations - took a whole lot of work and a lot of data to do it on the Camaros.

I gathered the information directly from the Pontiac service manuals. I agree that depending upon the timing of publication, some of the codes may have changed, but were authored by GM and considered accurate at the time of printing.

There are separate codes for auto and manual for each configuration, due to the trans cooler tanks. I will double check the code published for the '69 with A/C, thanks for bringing that to my attention.

Kurt, reading your page, the diameter of the four blade fans used on Ram Air Firebird and 396 Camaro is larger than the diameter of the four blade fan used on the L6.

Through 1968, the OHC had an air cooled 2-speed transmission behind it. Not until 1969 was a TH350 used, and not all auto-equipped OHC's had TH350s in 1969.

An air-cooled tranny does not need a cooling circuit on the radiator, so Pontiac used the same part number for both manual and automatic applications.

Edit note: There were also radiator cooled automatics installed behind OHC's in '68

I agree that service manuals tend to be much more accurate than the parts manuals, but they can have errors.
Someone had posted the other 69 radiator codes on a forum. Not sure what their source was, but a couple of the codes were different.
None of the Camaro service manuals have radiator tables like that. Y'all are lucky.

Really? I've never seen a different size fan. I'll have to ask around. My 396 car had a clutch fan, so no help...

PMI,
I didn't realize some trans were aircooled! Thanks!

Kurt, I have one of the 9794230 if you can find a 9798940 to measure.
