I apologize if I am placing this in the wrong forum, but I bought my 1973 240z with an l28 in it. What radiator do I get for it? an l24 one, or l28 one? Thanks!

I believe the 280Z radiators are taller than the 240Z radiators, so you would need to use one designed for a 240Z.

The 280Z radiator will bolt right in, but it is taller and the lower tank hangs below the radiator core support. It would be easy to damage/puncture the radiator lower tank. Be safe and use the 240Z radiator.

Alright, 240z radiator it is. Thanks!

I'd recommend either a rebuilt and re-cored 240Z radiator, which has been built with 3 or 4 cores - replacing the original 2 or a 280Z rebuilt the same way radiator.

True that the 280Z radiator extends below the radiator core support on the 240Z's - but is only a inch or two - and still well above the steering rack.

These now 38+ year old L24's require far more cooling capacity than they did when new, and they had marginal cooling capacity even then.

FWIW,

My experience running the 280Z radiators would not support that. I've ran them in 240Z's since the late 70's and I've never had one damaged. Anything that will reach the area a couple inches below the bottom of the radiator core support - will also tear out the steering rack and front cross member..

FWIW,
