Harrison radiator number ID help?

This is the number 3113454 that is on the top right of the radiator next to the harrison logo and pat number? Does any one have any idea on how to ID this radiator with the numbers off of it?

 

looks like a 1940ish number, not Chevy though....

pictures are ever so helpful.

 

Here are some pics.

 

Don't know what it fits but the "46M" stands for Dec 1946

 

Those inlet/outlets remind me of a 47 Chevy car rad....

 

I looked through my Hollander's Interchange manual and my 1929-1949 Chevrolet Parts manual. The only number I can find close to 3113454 is 3113453. Sometimes the GM casting or stamped part number is one or two digits different from their listed part number, so I'm guessing your radiator is for a 1940 Chevrolet truck, models KC, KD, KF, WA, WB & WC (heavy duty). You might want to compare it dimensionally with one.

Sorry, best I can do....................

 

Didn't show up in my 46 or 59 chevy parts books. Maybe in the 54 manual? nope...

 

It's not in my 42-56 Pontiac parts book.

 

Well, there goes my theory out the window, Squirrel......................

 

Lower outlet is bigger than Chevrolet - may be '40 -'46 GMC.

 

Ok thanks its NOS and never been on a truck before it still has the mounting hardware in the coth bag from the factory. I'm going to try and adapt it to my 1946 chevrolet pickup core support. The radiator itself is the same size and with as the factory radiator just the mounts are 1/2inch wider. I was kinda thinking maybe it went to a 1946 chevrolet or gmc COE truck?

 

WWII spec part?....just saying....

 

with a late 1946 build date stamped in the top tank, it's not a WWII part.

The chevy book would list it if it were for a bigger chevy truck, they were all in the same parts books back then.

Probably GMC. Make it work.

 

Has inlet and outlet like my 1937 Pontiac 6 cylinder but my radiator cap is on the driver's side. Kent1003

 

Well I'm back digging up old posts. I still haven't figured out what this radiator goes to. I still have it and have not installed it. I think it might fit a 1940 Chevrolet truck?

 

I see that you asked this question a decade ago, so I was going to ignore it, but since you followed up in '18, I figured I'd help.

It only fits the 1940 K & W 1½-ton trucks, as well as ½-ton and ¾-ton K & W trucks with heavy duty (3") cores/ All other light duty wore a 2" radiator core.
