This tag on ebay shows it for a Buick.

donnie, do you have a whole radiator, or just the tanks. i am in need of an IA tank for my 70Z project. UPS did the tarantella on mine when shipped! according to the nova research group. it is a 3 core 70 man trans radiator. probably fits alot of models. is there a tag still on the radiator. that would narrow it down more.

[Donnie]

Buddy,
I was thinking about buying it, but it looks like I need IA and XP tanks.
I'm waiting on tag info right now.

[Donnie]

Tag info, IA, CF, 53, SN.

Donnie what car is the radiator for? I have a bunch as an example this December BQ with tank codes IA XJ(L78/LS5/LS6 4 speed if I remember correctly) - let me know and I will dig them out and take a look for you.

IA and CF are Auto trans tank codes use on a bunch of cars for 2 and 3 core rads. SN code is 'I believe' a Monte for a 400-2 small block (LF6 265hp Turbo-Fire).

Thanks for help the guys!

when I bought the 69 L78 Chevelle it didnt come with the correct radiator. so I'm looking for one now.
came across the one I'm asking about for sale just trying to make sure its right for my car.

from what Phil told me I need IA &amp; XP tanks with a BJ tag.

[Kurt S]

I take it you have an auto?

BJ tag had IA and XI tanks in 70.
I thought for 69 it was BR, but I'm not the Chevelle expert.

[Mr70]

SN is a #3015099,used on 1970 MCarlo 400/265HP LF-6 w/Auto.Trans.

1969 L-78 Chevelle w/auto. got a 3 core BR coded radiator,part #3019205.This same radiator was also used in any 1970 &amp; 1971 Chevelle,Monte Carlo or Elcamino w/LS-3,LS-5,LS-6 engines,or optional heavy duty equipped radiator,or Air Conditioned equipped too.

The 1970 L-78 Chevelle w/TH400 got a one year only BJ coded 3 core radiator,part #3017239.
Because of the extremely low production of these,it's one of the hardest radiators &amp; tag to find.
Other then my original,I've only seen one other.The vast majority are M/T.

The reproduction market is NOT manufacturing these tags correctly,to the original design.

[RPOLS3]

Is there a difference between the embossed/stamped code on the tank and the code on the tag affixed to the tank? Where they both used or was it different on different years? I assume the correct code should be what is listed in box #45 on the build sheet (on cars with build sheets)?

Thanks - I am also trying to understand what is correct as well.

Jake

[Donnie]

Rick,
would the BR code be IA &amp; XP tanks?

[Mr70]

Jake
The Tag listed the tanks used to make that particular radiator..i.e. IA &amp; XP tanks were used to make a BR radiator.
BR is also shown in box #45 of the bsheet.

Donnie
Yes,a 1969 BR used IA &amp; XP tanks.It was the measurement of the various cores that were different amongst specific radiators.
BR used .16 Convolutions,meaning size of the cooling fins.
BJ used .18 Convolutions,meaning size of the cooling fins.

Below is the original off my '70 L-78,along with the original drain tube clip.
Notice the difference between this one &amp; todays repops.
Also,among other noticeable differences,notice the repops do not have the 7 digit part # stamped into the bottom of them,like the originals,nor the last number indicating the month.

[SS427]

Donnie, I have a complete BR radiator in my parts room if you need measurements or photos of any part of it.

[Mr70]

To answer a few PM's @ once...
In the Chevrolet family:
BC,BE,BW,BK,BO,BJ,BQ &amp; BR radiators all shared the same Harrison IA driver side tank.


BC,BW,BK,BJ,BR shared the same Harrison XP passenger side tank with an oil cooler,(Auto.Trans.)
The 4 core PD radiator did too.(Auto.Trans.)

BE,BO,BQ, shared the same Harrison XJ passenger side tank w/o an oil cooler.(Man.Trans.)
The 4 core PA radiator did too.(Man.Trans.)

The 4 core PA &amp; PD used IF Harrison driver side tanks.

It was the size of the cores &amp; their cooling fins that were different among them.Other GM vehicles used these same tanks too.

[Donnie]

Thanks Rick.

and Rick N. you can send that radiator to me. I think you have my address if not I'll send it to you <<GRAEMLIN_URL>>/beers.gif <<GRAEMLIN_URL>>/biggthumpup.gif

[XXXGoldL34M20]

Hey Rick.
What were the break downs of the codes of the small hose bracket like the one you have pictured showing AE,
Mine has an H stamped there.
Any Meaning to these letters?

Geez, you guys pm me, on PMS, Go BO, and BJ, and OH NO!
Sounds like a Ivy League California Valley Girls Gone Bad Clip <<GRAEMLIN_URL>>/naughty.gif

Thank you Rick!

This is the great kind of information I love about this site.

So as not to hijack the thread I will PM you with another specific question about my car.

Buick should have a SJ metal tag.

Donnie,

The reason I said the code is BJ, is that is what is listed on this build sheet for a 69 Chevelle L78 with auto trans. See below:

This is a known low mile original survivor car. I deleted the VIN intentionally. The car is real with less than 5K on the odometer.

This is the second L78 auto 69 Chevelle with the BJ rad code that I know of. I can't guarantee the radiator tank codes at this point. What I mentioned earlier was based on the ebay auction for that tag. I know the IA tank code is good, not 100% on the trans cooler side of the rad. Jim, do you have a 3 core 69 BB auto trans rad to shed some light on the tank codes?

[Kurt S]

If I'm reading the date right, that's a later 69 L78. So probably a running change.

Interesting. I've seen a BJ tag with IA and XI tanks and 16 core code.
At least the second time I've seen conflicting tags.

Phil,

Nicely optioned L78 <<GRAEMLIN_URL>>/biggthumpup.gif

In the for-what-it-is-worth-file, a friend of mine's 69 Chevelle, L78/automatic built in January of 1969 also had the &quot;BJ&quot; radiator code on his build sheet.

Phil Woj

[Donnie]

Thanks Phil.
so, it looks like it could be either or.

Since there seems to be a lot of knowledgeable radiator fellas here can you tell me what an “AG”stamp on the fill side & “IA” stamp on the left side means with a 26.5” wide core would fit ...

Thanks Rob

[ban617]

Manual transmission also

[Kurt S]

I've seen it before. It had a broadcast code of RP (could vary depending on the core). No idea on the application.
