    I replaced them on two of mine. 1 had 700 thousand and the other had a million miles on them. The front mounts were wore out and the fan was getting into the fan shroud on the botton. I changed them all and it set the motor up 1/2 inch. Now the fan is in the center of the shroud.

    On the Columbia chassis, the bottom center radiator mount wears out as well. It causes the bottom to slip forward pushing it into the hood hinges.

    Well, this one couldn't pull itself out of a ditch if it had to, let alone up a hill. No guts at all on hills. Shouldn't have to feel like you need to push the truck up a small hill.

    Run it @ 1375-1425 for economy and 1475-1525 for power.
