Wow... what a job. Our 01 has 115k on it now and has started to spring coolant leaks. The big coolant supply tube from the water pump to the oil cooler had a leak from the gasket where it connects to the water pump. The water pump was weeping from its weep hole. Accessory drive has to come apart, harmonic balancer has to come off... never seen so many gaskets and o-rings in my life... just to change a pumphttp://www.dieselplace.com/forum/smileys/Confused.gif. And no, I haven't taken a crack at changing the injectors yet... dealer did that for me at 99,500 mileshttp://www.dieselplace.com/forum/smileys/HiHi.gif

Sorry to hear of your water pump problems. Factory does give coverage up to 100,000 mi, and notice you are out of that Bummer. http://www.dieselplace.com/forum/smileys/Cry.gif Good Luck
