I'm looking for an original Harrison radiator for a 69 Camaro 396/375hp with manual transmission. I understand the tag has "ZD" but what do the tanks have stamped on them? I've heard several different things and I would like to know the "facts" so I won't get burned.

Tanks are the same, L6 to L72. Only difference is manual or auto.

Bob, I'm talking about the tanks on each side of the core.
Do the tanks have any stamping on them besides Harrison?
I know the radiator I need is a 3 core and the tanks are the 4 core size. I was told one tank is stamped "OO" and the other is "IL" but I think that is for a '68 BB car. Does this radiator not have "ZD" stamped on the tank besides the tag?
Does anyone on this site have a manual 396/375 BB with an original radiator tank?
I have looked for this information in several books but there is no mention of this. There has to be a way to identify the radiator besides the tag, surely.

I find it hard to believe no one on this site knows the answer to this question.

Neal, I agree that the amount of radiator info is scarce. From what I have seen of small blocks, the Harrison tanks are all the same, only the core size, manual or auto tanks and panels that the core mounts to the tanks are different. The Harrison tanks have "Harrison" stamped in the tank on the side near the cap. the "cold fill" is also stamped. Other than the tag, that's it. Non-Harrisons have different ribbing, tank supports, cap angle and location of overflow nipple.

I suggest you do what I plan to do. Find ANY Harrison 1st gen 4 speed radiator (no trans cooling fittings) and have a reputable shop recore it to your specs using the Harrison tanks (make sure they understand that the tanks are very important!). The tag just clips on, so don't give them that, keep it to yourself.

Since you are having it recored anyway, go up 1 row size for comfort. You really can't see the number of rows when it is installed.

Luck, Kevin

I'm not sure what was unclear in my response. All the tanks are the same 'cept for auto/manual. Find a L6 radiator and use it's tanks and you're set.

Kurt,
Are you sure about this?
I have talked to several people and all say there are stamped letters on the tanks along with the name Harrison. I have also been told that there are two different size tanks, one that is a 2 core size and a 4 core size. Maybe I have been misinformed, that's what I'm trying to find out.

I have a original Harrison Radiator in one of my 1968 Nova SS 396 cars,ZD on tag IL OO on side tanks,3 core.4 cores were COPO or A/C cars.This is true for 68 and 69 cars.Have original 69 Nova 396/375 car and rad is same.

Sep 6th, 02, 03:11 PM
Thanks 68Baldwin,
You are the third person that has told me that. I have talked to quite a few people and this seems to sound "correct". There is not alot of information on this subject. I'm suprised CRG doesn't have this info.

By the way, is the "IL" on the fill tank and "OO" on the drivers side tank?

Neal, I saw your post over on yenko.net too. You've peaked my interest, so I pulled my 2 SB Harrison rads (2 core and 3 core 21") out of the shelf and looked closer. The pass side has the OO like the rest, but the drivers side has an HI or IH depending on which way you look. Maybe you are on to something about BB tanks being different. Or at least on the drivers side. Where the IL tanks the curved neck ones?

I didn't say there wasn't stampings in them, just that they are the same.
4 core are different (forgot that), but my Z rad has the same tanks as the L6 auto rad I have. And all others I've seen. And the same as what you need. http://www.camaros.net/forum/smile.gif

There's also part numbers on the ORIGINAL radiator tags.The flat spot where the clip side is to fasten to tank is where it will be found.Clean and scrape very carefully and you will find it.I have a original Delco Remy catalog that has Harrison Radiators in it and my part number for my Nova Original Radiator tags match in the book,68 396/375 3 core.I will check the location of the IL and OO and post the imfo.

68Baldwin,

I found the "OO" as everyone is talking about (on the passengers side), but the only thing I can see on the drivers side is one letter "R". (I also found the "Harrison" and the "Fill Cold" on the passengers side.) In addition, I also found a tag (upper passengers side corner on the front of the radiator) that says:

Made in USA
60 107
3R 10187

Nothing else. Any hints on what I've got?

Thanks
Ed

You have a CLONE HARRISON RADIATOR! just kidding http://www.camaros.net/forum/smile.gif

I have yet to talk to anyone who knows what the letters are for.

So far I have seen:
OO 3 core BB
OI 4 core BB curve neck
IL 3 core BB
IH ? core SB

I think the "R" is on the bracket that mounts to the tank.

Maybe some other people will post their
letters and we will start to see a pattern.

Neal,

Thanks for the quick scare!!! You had me until I read on...

So, I'm assuming then that the "OO" is the key here. (By the way, you are correct. The "R" is on the bracket.) I'm also assuming that the "107" is the Julian date the radiator was manufactured (April 16th, in this case, as it would be the correct time frame for my 05D car), and that the "3R" refers to "3 row". I'm fairly sure that the "10187" is the last 5 digits of the part number. I assume this because I've found several parts numbers in my P&A 34 that are very similar. I.E.:

3010181 67/68 Camaro W/PG (w/CAC & HD radiator, 327 & 350) 1st design

3010180 67/68 Camaro (w/CAC & HD radiator, 327 & 350) (exc PG, 2bbl) 1st design

etc, etc, etc ...

The problem is that the P&A doesn't list a "3010187".

I have no idea what the "60" refers to though. Maybe a "style" designation?

Neal,

Good info. Pertains mostly to 69 cars, but interesting anyway. I was hoping to find something regarding the "10187" part number I have on mine though. I'm going to have to look for the small letter between the "OO" when I get home...

Your radiator should be the same. Do you have a photo of that tag your talking about?

bertfam
Sep 10th, 02, 03:55 PM
Neal,

Here's some additional info...

There IS a capitol "E" between the two "O's"!! A smaller font as described, but it IS there none the less. I'm going to assume this means "May", which is exactly the time frame of my 05D built car.

I've also put a picture of the Radiator Tag on my WEB page as you requested. You can either go to my Home page (see below) and click on the "Misc Stuff" Icon, or go to it directly at:

Misc Stuff (http://home.pcmagic.net/bertfam/misc.htm)

Now if I can only find some info on the "10187" part number...

There is a guy that has addded a post on the supercar website that has a radiator with an odd recessed letter. Looks like we are missing something here. This may not be a date code or some of the letters were not used. I wish someone would chime in that knows what these mean.

Thanks for the pics. I posted them over at the other site hoping we can find an answer.

Neal,

Thanks for the link. This is really getting interesting!! I'm not a member of the other site so I'll convey my thoughts here. You can pass them on if you think it's worth it...

Kurt states that my tag is probably a rebuild due to the location (and it could very well be). However, would a rebuilt core have a tag with a GM part number ("10187") stamped on it??

Also, I disagree with the statement 69L78NOVA made, in that the "M" couldn't be a date code, as his car was built in March, 1969. "M" (December, 1968) is well within the accepted norms for a March, 1969 car. Especially if the tank was stamped in late December, and his car was built in early March.

Also, I thought my tag was the one we've been talking about all along. But considering what Kurt said ("location"), it must not be. Where is the tag located normally? If I can find that one, it may help...

I have a three core 23" radiator that has harrison on the fill side tank and the letters "C B" stamped on the ribs. On the other side I have "HI". Don't know if it is original, but a friend of mine has a 1969 Z/28 that has the same letters.

KevinW
Sep 11th, 02, 03:47 PM
Hey, this is getting interesting now!

I took a closer look at my 2 SB rads and I miss-decoded them.

The 21" 3 core pass tank is "OG", date code of H with IH on the drivers (this is a auto trans).

the 21" 2 core pass is "OD", date code of G and IH on the drivers side (this is a manual trans). The "OD" is the same as a 68 Z/28 and the IH tank is the same as a 69 Z/28.

Funny thing is (not really funny) is the two smaller stamped letter groups on the tag MATCH the stamped tanks.

I always wondered about the other codes on the tag. It's the tank codes!

So the large code is probably the application code, the 2 smaller codes are the tank codes, the only thing left is the number code below the tank codes. My 3 core is 84 (ZC application) and the 2 core is 67 (UC application). Both have a "0" (zero) under the C on the right.

Anyone?

Kevin

Looks like all the "fill" tanks are date coded but are the "driver side" tanks dated coded also?

That is most interesting that the tag has the same information as the tanks.

bertfam
Sep 12th, 02, 04:18 AM
Boy, I have looked and looked but I can find NO stampings on my drivers side tank (other than the "R" on the bracket). I also cannot find another tag. Of course, it's impossible to see the front of the tanks due to the location (being too close to the support). Where exactly are the other stampings and the tag located? If it would help explain, use the picture on my WEB site and circle the area where you're finding the stampings/tag...

The "CB" rad is correct for a Z/28.

Can not help out on this radiator topic. I too, would like to know info on my radiator. If anyone can help de-code, here is the info.I have a 4 core curved neck out of my 69 camaro . The left tank bracket has only a large "R". Nothing on the tank. The right side tank has Harrison and below that Fill-Cold.Also on the tank is "A 5" There is a tag that has "S" on the tank. On the right bracket is a tag the says Har/ri/son, Lockport NY, 3018623,Also a large 74L. Any info on this tank? Can anyone break these # down? It is also set up for automatic.

Leonard,

Can't help with the numbers, but according to my 1968 issue P$A 34, your part number 3018623 breaks down as:

1969 Camaro with CAC (Air Conditioning) and Turbo 400.


68Baldwin, I can't find any info on yours. Sorry...

Dan,

A VERY good question!

Going by my P&A 26 (Dealer Parts and Accessories Price Schedule), it looks like there WERE radiators that were shared between the divisions. For instance, Part number 3019205 (69 Chevelle with HD Radiator, CAC, Turbo 400 and 396) was shared with Olds and Pontiac. Others, like Leonards 3018623, was just used in the Camaro. I guess it would depend on the application. I'm sure John Z or Kurt could give additional info on this...

Ed, I took my radiator out today to have repaired and also found a tag similar to yours that you show in your pic. Mine is on the upper right engine side welded onto the fins, about 1.25x.75. on this tag there is stamped

Canada
3R 10187
29 51 94

"R" on drivers side bracket
"Fill Cold" on pass side tank
did not look for double o's, but ill look later.
Curved neck

Any thoughts on what this is?

Could I have a Canadian Car, are there other signs that it would be from Canada?

WOW! That's VERY interesting information here, eh!! (For all you Canadians...)

Can you take a picture of your tag and email it to me? (My email address is my user name.)

John Z, Kurt, Mark... any ideas at all??? Anyone else out there have one of these on your radiator?

As for your car being Canadian, if it is, you should have the Canadian Trim Tag on the car. Even if it doesn't, it doesn't mean the car wasn't imported to Canada. This was common also... The original owner may have traveled down to the States, bought the car and then drove it back home to Canada. I'm not sure about tariffs though. I wonder if it was cheaper to buy a Canadian car, or to get a US car and then pay the extra taxes...

Ed, from what I've been able to find out, my radiator tanks are original, but it has been recored, and the tag is most likely from the recor. as far as having the same number on the tag, Dont know if it is a coinsidence or if that is the part number for this core.

Thanks Scott... I can't believe that Chevrolet would recore a radiator if it went bad while under warranty. It would be easier to just replace the whole thing. It must be from an outside source... I found it interesting that your number and mine are the same though! "10187"!

No, I know that... I was just assuming that the dealer would not recore a radiator, mearly replace the whole thing. I was wondering though if GM furnished just cores. I can't find any in my P&A 34. The only thing it lists is the whole radiator. What has me interested is the part number "10187". It's a lot "like" a GM part number.
