Fan clutch update. So, I started out with a Autozone fan clutch, it failed afte 3k miles, so I put in a Napa unit that looked exactly the same as the Az unit. The napa unit failed just like the Az unit. Got a warranty unit from autozone and put it in and wallah!!! all works fine, the last unit does not look like the first Az unit or the napa unit. warrantied the napa unit and carry it onboard. So, with my 180 thermostat the hottest it runs about 210 on long up grades pulling a 3100 lb load, normal idle temp is about 192 with AC on. Tranny temps will climb to 160 on the long pulls, but on flat runs it is 150.
I switched over to the newer propane AC gas/coolant and the ac unit works perfectly too. the SC frigitte AC unit is junk. Had to tape over "out side air in door". The new AC coolant is amazing stuff, I actually get 42 degree air coming out of my dash air vents.
