1972 W30 Radiator & Tag Question

What are the correct radiator tank codes for a 72 W30 as well as the correct radiator tag?

Thanks in advance.

 

Stefano,

CE coded 3 core for 3:42 cars. My info shows IA and AA for the tanks on this radiator. There is a questionable OG, as it is mentioned in assembly manual and service manual but not in inspectors guide.

ZR coded 4 core for 3:73 cars. I do not have the tank codes for this radiator. I would like this information if you are looking at a car that is so equipped.

There was a thread about 72 W radiators. Search for my posts to find, as I responded.

Just to contradict the information above. I think Eric Jensen had a 3:42 low mileage car that had a 4 core radiator.

That is correct. I can not remember what the code was for that radiator. I sure wish I documented that car better before I sold it. I bought it in 1996 with 16,000 miles on it.

Don, I have a PI 4 core I pulled from a 72 Supreme U code car. I did not see the PI code in the assembly manual. Do you have any info for the PI? I sure feel it was the original but it may not be.

 

Eric,
I did not find any information on the PI radiator. I looked at several different years.

I know this is an old thread but to correct the record.... I was looking at old pictures I have of that car and I was wrong. It had the 4 core top plate with the special rubber insulators but it is the 3 core radiator. I sure hope I did not make troubles for anyone on this.

 

Just adding on. This is info I just got from Al Sutton showing radiator codes for 72

 

Don,
I have 72 Cutlass S and the radiator tank code is OF. Right now it's being re-cored to a 3 row.
Do you know what the IA, AA and 3 digit code under the AA represent on the tank tag?

 

That is the number stamped on each tank of the radiator. The IA is a real common tank and on most radiators but the other tank is the one that varied most often. I "think" the number is the number for the core but not sure of that. The radiator tag is like an assembly instruction as to what parts go into that radiator.

 

Where would that be stamped on the tanks? I have a 3 row in the garage I can look at until I get the original back

 

Stamped on a tag attached to radiator

 

Here is a picture I robbed off the net. They are not really hand stamped but more stamped from the mold. You can see the stamp on the tank matches the stamp on the tag. The other tank on this one is also an IA. All this put together creates a BK radiator (chevelle)

 

To add to what jensenracing77 posted, the small A embossed on the tank is the build date. A = January.

Don, I don't see the small A on my computer display but accept that it's there. I do have one more question: What does the number '49' signify on that BK tank? My OEM tank has 137 and is coded OF. Can't find that anywhere on the cooling section. I saw another tank similar to mine (posted by Bigdooly) that showed an OG radiator and it was IA, AA, 138. I'm really curous what those numbers mean.

Thanks Eric, I didn't know to look for that when I pulled my rad, but it should still be there when I get my rad back from the shop. They said they would also keep and return my harrison tag with the new re-cored 3 row radiator. My tag shows tanks IA and AA. If you know the answer to the question I asked Don, please feel free to chime in.

 

I’m gathering information on this very topic. My interest lies in the x code cars. The documentation available is very interesting. 1972 production utilized many radiators. The X code cars used a 3 core rad with a 3 core tank on the drivers side and 4 core tank on the passenger side. Compiling a file. Al
