Dealing with overheating on the 3.0?

So I have a 1990 second gen 4 runner I’m want to know if there is a alternative to helping the overheating problem on the 3.0 like maybe a thicker gasket or something like that.. or should I just swap it?? I’m thinking 1jz or 5vz... anyone have input on this subject?? Any advice will be highly appreciated.. thanks

 

what overheating problem? I live in the desert and never had any over heating issues?
pulling boat, ac on and 105 out, and no issues.
check your fan clutch should be hard to spin with engine off/

 

I never seen a Toyota that was sound overheat, ever.

 

I had all kinds of trouble with overheating. Water Wetter helped some, as did an aftermarket aluminum radiator, but I eventually fried the motor (at 220k) and put in a 5VZE, which has never gotten hot at all.
