I’d prob replace the thermostat first, it could be sticking and they’re cheap.
Also, as fanboy mentioned start paying close attention to the fan/clutch operation pre post and during the ascent.

Right you are.Put on the Aisin fan clutch FCT 014 for 127 dollars delivered thru Amazon.I raced it hard up the hill

with AC on and couldnt move it past half way mark,gauge horizontal.

When I bought car a race up the hill left fan blasting on hard.I didnt know thats a classic sign of fan clutch failure,so changed that first and problem fixed.Thanks to ALL for once again educating me and fixing the car.Oh,and it didnt fail in the full on mode,just no fan clutch engagement when temps climb.
