My truck temps started going crazy yesterday. Got it home and did a little research on-line and found out these Cummins water pumps can go out anytime after 70k miles. Mine has 140k on it. Made a trip to NAPA and bought a lifetime warranty pump for $47, under two hours and had the old pump replaced (yes the bearings were shot). I park on gravel, so didn't catch the telltale territorial markings....should have checked out the strange noises at startup a little closer (thought it was just belt slip). Gotta love the way Cummins made it easy to change the t-stat and water pumps on these engines. Anyway, just a heads up to you Cummins guys out there. I read the dealers charge up to $700 to change out the water pump!
