Water pump pulley ratio high RPM offroad

Have you tried running in 4 high range? That would drop the pump rpm?
If it gets hot in high range its not your water pump rpm.

I don't...because trans will get hot lol lol. plus my stall is wrong, gearing is wrong...can't get into the RPM needed to climb. Never ending battle!!!!

I think you hit the nail on the head stating the rad is toooooo small. I just was hoping for a simple easy and quick fix :( But, I might as well just go all out and do it rite.
