In 90+ weather when pulling a long grade my 05 Bounder 34m with a 300hp Cat will run in the hot on the guage and the yellow light comes on, I will down shift and let up on pedal. When top of pull it cools down. I had it at Freightliner and they cleaned out the rad and cac and adjusted the water pump belt, helped some. Any thoughts?
seeing as the rad etc is clean the only thing I can think of is the fan clutch is weak and slipping ?
I know my 425 side cooling ISL will run 200+ on a hard pull and as soon as I lift and start coasting/cruising it backs right back down to 180 area;;
