70 Chevelle radiator tank codes

[Rixls6]

Are the radiator tank codes "CI" and "IF" correct for a 4 row radiator in a 70 Big block Chevelle? My build sheet shows PA as the radiator code. (see pics of tank codes below)
Unfortunately my original radiator is missing, but I have this recored one I found that I'm hoping would be correct.
Thanks.

The original ones in my 4 speed ls-6 say XJ and IF.

[Rixls6]

Okay thanks.
Then if XJ is the correct tank on yours, is yours an automatic car? What code is on your build sheet for the radiator?

[SS427]

His radiator is a PA.

[Kurt S]

I have PA noted as using IF and XJ.

[Rixls6]

I appreciate the replies.
I guess I need to find an XJ tank.
Does anyone have one they will trade for a CI tank?

Her are some pics of my tank codes and tag.

I have an original XF, I was told was for an LS6 with A/T and 4:10 gears. Is this correct?
How much is it worth? I'm interested in selling it.

I don't get it. If your XF tank is for an automatic, maybe someone put the trans cooler into it later.
The other guys are showing an XF tank as being original to an LS6 4-speed car, which wouldn't have a trans cooler in it.

Don't know http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif
I only saw mention of XJ and IF
mine is XF

You're getting a lil backwards.Re-read the posts again,and you'll see it makes sense what the others have submitted.
X J is a Manual trans application,and X F is a TH400 application.
When any 1970 LS6 Chevelle was special ordered with the 4:10 posi upgrade,that canceled it's standard Big Block 3 core radiator,& it came instead with the larger capacity Big Block 4 core radiator.Which could have been either the PA manual prefix,consisting of the I F driver side tank,and X J Pass. side tank,or the PD TH400 prefix,which consisted of the I F driver side tank,and X F pass.side tank.
Understand that these two radiators were used as the Big Block Heavy Duty cooling radiators on the 1970 LS-6 Chevelle/Elcamino,but not exclusive to the them,as they also came as standard equipment on the 1970 L-34 & LS-5 Chevelle/Elcamino when equipped with optional Air Conditioning,or if just RPO KO-1 H.D cooling was ordered on them and that would include the 1970 L-78 Chevelle/Elcamino too.
In 1971,the PA & PD radiators were also available on all the BB Chevelle/Elcaminos under the similar circumstances mentioned above.
I believe your C I Passenger side tank was used on the 1972-74 GM A-bodies.

[Rixls6]

OOPS,
My bad. I was mixing up the XJ and XF.
Thanks for straightening that out.

[DaveC68]

Rick,
If I understand correctly, the XF I have would be correct for my 71 SS454 A/T Monte with air?
I guess I'll be hanging onto it.
thanks for the info.

[Mr70]

That's right DaveC.
Your 71 Monte Carlo LS-5/TH400 A/C equipped used that (4 core) P/S tank,along with the 3 core D/S tank denoted as I A,and the overall prefix tag BR.That was the Heaviest Duty radiator available for that particular vehicle.
That radiator was very popular among 1969-71 Chevrolet A & G bodies,part #3019205.

Rick - How does option VO1 heavy duty radiator fit into the mix? I have a 70 BB 4-speed car with that option. The build sheet lists a BQ radiator, and I have the original radiator with intact tanks and tag which indicate IA and XJ tanks.

[Mr70]

Sorry Rainer,that should read RPO VO-1,not KO-1..LOL..(I was reading about the KO-Motion Vette before that.)

For 1970,the BQ got the nod as the optional Heavy Duty cooling rad. for some,(i.e..Not Super Sport) Manual trans. equipped Big Block Malibu/Chevelle/Elco/Monte C.BR was for those w/Auto.Trans.
It's a 3 core and was the highest cooling rad. offered for some specific vehicles.
The larger capacity PA,PD 4 core was not always possible/recommended/needed on every single vehicle when Heavy Duty Cooling was requested.

[DaveC68]

Rick,
One more question while we're on the topic.
what is the correct code for my 70 4 speed LS-3 Monte?
originally NO A/C and NO heavy duty cooling option.
It had been replaced when I got the car, and seemed to have a very thin core with large tanks, but did not have the extended tabs on the rad support or hold down.
thanks,

[Mr70]

That would have originally been built with a std. 3 core radiator,part #3016908 carrying a BE coded prefix tag.

BTW-Parts Place,Ricks Camaro & others are selling reproduction radiator tags now,albeit not 100% authentic to the originals.The reproduction Chevelle/Elco/Monte C. applications tags I've seen so far are:
BK-BE-BO-BJ-BR-BQ-PA-PD.

[DaveC68]

Thanks Rick,http://www.yenko.net/ubbthreads/images/graemlins/beers.gif
Came to my senses after the fact and checked box 46 on the build sheet too. it shows 65 BE.
Just took a fresh look at the 71 SS monte build sheet too.
heavy duty rad is not listed as an option and the build sheet calls out PD

[Mr70]

You're right Dave,sorry for that mis-information there.
I glossed over the fact that your's is a 1971.
My earlier reply was correct for the same equipped 1970 Monte Carlo SS.
1970 SS Monte Carlo's were set up a lil different,and that's what I included your's as.
The following model year,they made some changes.
In 1971,they received the 4 core radiator upgrade as now automatically included with the AC option.
You won't see a notation of RPO VO-1 Heavy Duty cooling on the buildsheet as it was included with RPO C-60 when the Super Sport option was also included now,so redundant to mention it.
Your 71 M/C was originally built with an X F P/S tank & an I F D/S tank to make up your 4 core PD radiator,part #3017248,and was shared with various other 1970-71 Big Block Chevelles & Monte Carlos.
Hope I've helped you some..
