got a 2003 granite e7 427 dump truck just bought it with a known overheating issue it gets hot when loaded it has a new radiator,intercooler ,water pump ,and a thermostat when we got it home we replaced the oil cooler . it was drove home a thousand miles and only heated up in the mountains . its doesn't push out water unless you get it hot no oil in water or water in oil i can hear the fan kicking in and it stays in when it heats up the truck only has 350000 thousand miles on it the truck doesn't have a boost gauge it seems to run alittle high on the pyro it runs about 850 to 900 running down the road at highway speed up small grades but it doesn't smoke eccessively what direction do i need to head next
