We are presently having our radiator replaced at the Freightliner Dealer in Las Vegas. While sand blasting and powdercoating a few of the parts that hold the radiator to the chassis, we have found the large steel water line from the motor to the radiator was badly rusted. When cleaning, holes developed from the rust. I cannot find where to buy a new one, so brazing and powdercoating is my only option.
Occasionally inspecting this water line would be a good idea if you live in the East, with the salt on the roads.
