I am running 37 BFG Humvee tires on my suburban with a 6.2 non turbo/th400/np208/14 bolt FF 4.10. It seams to drive well in town and on flat freeway at 60-65. But when I hit a decent hill it slows down and if the hill is a long run it starts to heat up to 215-220? I have a Autometer temp gauge installed right before the thermostat in the crossover housing. Most of the time it stays at 185-190.
Here are some other specs: 180 degrees robertshaw(prestone) thermostat. I did use a 190 robertshaw before with same results. A cleaned 4 row stock GM radiator. Standard water pump (unknown condition, since I bought truck). Fresh coolant 50/50 green stuff.
Is this normal? I still have my dummy light hooked up too and it never came on (not sure what temp is comes on anyways) Is the temp after the heads that much hotter then the temp in the heads?
Also I have pulled my lawnmower behind a small utility trailer and it will slow my truck down pretty good on any incline and heat up faster. I realize the engine I run is pretty powerless, but I want to be able to load up with my camping and hunting gear and go over the pass without overheating regardless of my speed.
