How to Maintain a Water Pump on a 5.9L Diesel Engine on Dodge Ram 3500?

The first step to servicing a 5.9L diesel water pump is to remove the battery negative leads and drain the coolant. Free the accessory drive belt and the brackets that secure the water pump and then wipe the cylinder block beneath the water pump clean. Clean the surfaces of the gaskets as often as they need to be. If there are cracks, breaks, leaks, loose or harsh moving bearings or signs of the impeller scraping the body, replace the water pump. During installation, set a new O-ring seal into the water pump's groove, secure the water pump in its place and tighten the mounting bolts to 24 Nm (18 ft. lbs.). Once you have put the accessory drive belt back into place, add the bolt to hold the wiring harness above the water pump. Top off the radiator, attach both connections to the battery, launch the motor, let it run and make sure there are no leaks.
