Radiator ID Help

3 Attachment(s)

Hello all! I'm in need of some help identifying my radiator. It's in need of a restore/replacement as it's pretty beat up, leaking coolant out of the upper hose, I think the trans cooler lines running into it are leaking somewhere and it has some rube goldberg plug in the top right above the tag. If it's the original, I'll pull it and restore it but, if it's not original, I'll probably replace it. The numbers/letters on the tag are "IF JG OY 136 3023708". Thank you in advance for any help!

Looks like original. The plug is for a heater hose connection. Sometimes the 5/8" hose is connected there instead of on the engine.

Thank you! I'll plan to fix this one up.

the rad in my big block 72 has that same sort of tag,it's factory.i will check the numbers and letters on mine to compare to yours.the clip below that tag is for the overflow hose and what is plugged off,as Steeveedee said,is the heater hose connection.my heater hoses are not hooked up yet but will be once the inner fenders go back in.
