any one know what application a HD radiator with OJ stamped into the passenger side tank is for..... maybe Pontiac or Buick? And if so would it still work in a 70 Olds 442? It looks correct except possibly the overflow tube from the filler hole which faces the fender instead of the engine - otherwise looks just like a CI radiator.

 

I got some more details the passenger tank has OJ embossed in it, the driver side has IF embossed in it and the metal tag has an LJ embossed on it

its about 34 wide, 18 high and 2 3/4 deep

 

I've seen the "IF" and the LJ tag.Somewhere I have a chart with all of the radiator codes & applications.
BTW,your alternator chart that you sent was helpful.If you still have that,can you resend it.I must have deleted it.

 

thanks Brian, even if its not the exact radiator I may end up using it if it fits as it looks correct, though if it is a rare one for some odd application I prefer that someone who needs it gets it rather than putting it in the wrong car.

I'll send that alternator chart again.
