Is an FJ45 Radiator the same size as FJ40? See picture (1 Viewer)

Is a 1965 FJ45 Radiator the same size as FJ40? If the same size I will just order a new one. If not I will try to have this one boiled and cleaned
Thanks..

Yes.

Thanks, Mark!

Swapped them. Some rads are 3 core others 4. Newer are sometimes higher density which have more fins. I’ve been told a high density 3 core will match cooling capacity of a 4 core.

 

[Wadesters]

So your recommendation is getting a new one?

Yes

you'll find the new one half the weight of your old one
if your old one had the emblem on the top tank I'd keep it but it doesn't look like it is there

This photo shows a '78 FJ40 radiator in a '65 LWB FJ45 pickup. Fits great. I recommend a new radiator in your case, rather than trying to salvage the old one. Need input: 2F or V8? - https://forum.ih8mud.com/threads/need-input-2f-or-v8.1294392/page-3#post-14622992

Thanks @SteveH
New radiator ordered.

I agree with @3_puppies , always heard that the old 3-cores radiator were better made than the currently available 4-cores, if salvageable.
Off course it's hard to verify for sure but once you have both in hand could be interesting to weight them as suggested!

From what I've seen the overflow pipe points forward on the old emblem radiators compared to the RHS exit on later ones.
