    I have an 88 f350 4wd dually dump , 7.3 banks turbo 5 speed running a 8.5 western. It never had an tempeture problem in summer loaded. I have no problems while plowing, but running down the road 50+ it begins to overheat on hills, I removed the grill and a/c condenser. the helped a little bit but im still looking for a a better alternitive. ive been trying to find a cooler thermostat or maybe an aluminum radiator out of a powerstroke. thanks

    Fan Clutch - Put on a heavy duty one. Most likely it is bad. There seem to be allot of this going on lately.

    Do you know who makes a heavier duty one?

    You have to buy the expensive one that is a thermal fan clutch. The cheap non-thermal will not do you any good.

    Thermal fan clutches engage the fan based on a bi-metal thermostatic coil, which senses the underhood temperature. Non-thermal fan clutches engage the fan based on the shaft speed of the water pump.

    i have a fan clutch for a 1994 factory turbo IDI, one for a 96 powerstroke and one from a 99 powerstroke,
    im going to start with the 94, according to the specs its suppose to provide more cooling. not to sound like a cheap ass but i hate to spend $100+ on one if i have some laying around.

    when transporting, drive with the plow a few inches off the road. when you drive with it lifted all the way up you block air flow to the radiator.
