'04 2500HD Water Pump

Discussion in 'Chevy Trucks' started by Motorman 007, Nov 26, 2011.

  1. As my truck is approaching 100K miles I have been keeping an eye out for the water pump to fail as it is a fairly common thing on the 6.0 engine. Last week the engine was dry and Friday night I started to smell coolant. I was installing a plow for a friend yesterday and he said "whats that puddle under your truck?" So today's project was the pump (new), new belts, a coolant flush, and a new air filter just for kicks. Got everything at NAPA for about $250.

    The point of my post is that the water pump is a breeze to replace so most of you guys that DIY could easily do this. Take a good look at yours and be sure it's not starting to leak. There is a weephole in the bottom of the pump and that's where it starts to leak.

    Just replaced mine a month ago. Pump, thermostat, and belt. Has 95,000 on it. Leaked sometimes but not all the time but could tell it was burning coolant by the smell. Glad I caught it before I was knee deep in snow. Hope the radiator isn't next!

    Yeap - totally agree pretty simple & straight forward. I replaced the water pump, both belts, belt tensioner, radiator, fan clutch, upper and lower steering shafts, and power steering pump. Not a mechanic and did it all - referenced my Haynes manual, Google and...of course Plowsite. :) (all within the past couple of months - getting ready for the winter)

    6.0L are great. I wish they were all that easy. I just did one on a duramax yesterday, talk about a project. Removing the harmonic balancer to change a water pump... dumb.
