will a rad from an 81 fit in an 85??
also will an 88 v6 rad fit in an 81?
i have a v6 rad that i wanna run in the 81 and take the 81 rad and stick it in the 85,make sense?

Not even a little bit.

But here goes... I don't think any of them are swapable. It all depends on how they bolt to the Truck and where the inlet on the radiator is.

Go in take a look and if they don't bolt up the same doubtful.

At least the inlet problem can be solved with some creative use of hose.


Why would you bother with all that though?

 

broken 85 rad. so i went and bought a used one off some guy.turns out to be a v6 rad.im gonna build a high horse motor for the 81.so i figured id put the 4cyl(81) rad into the 85.and v6 rad into the 81.
whats wrong with that.
i see that the top hose neck is angled different.but i just wonder will they bolt up fine.im not worried bout hoses i will make something work.

 

Well I know a v6 will bolt directly up to an 84-88. So what remains is will an 81 match an 85. From there it is a transitive relation/formula. If A=B and B=C, then A=C.


The next consideration is clearance of fan and hood. Those are measurements which can be compared to each other with a tape measure and a soda pop; the pop being for periodic refreshment (can be substituted for beer, but since we are engaged in calculations, perhaps the soda is a more prudent selection. ).

Given Toyota's propensity to maintain consistent patterns, I'd bet the rads will swap. Even if you had to fabricate an adapter, you could find a way to mount it. The more salient issue is clearance.
