Can anyone give a sense of what it takes to replace the water pump inlet tube?
5 months/21k miles ago, I had a dealer replace the water pump and a bunch of other things, for about $5k, and I now suspect they forgot (or neglected) to replace the inlet tube. So, this past Thursday, I saw coolant dripping from what the service advisor said is the "rear torque mount", the lowest point immediately in front of the area where the transfer case would be if it were AWD (photo attached). At this time, I checked the weep hole on the top of the engine and the area did not have fresh coolant, suggesting the coolant came from somewhere else.
Well, I drove it to the dealer that did the water pump work (25mi/1 hr drive) and, upon arrival there, the area I previously saw coolant was dry/no coolant dripping. Coolant reservoir is in the normal range, but right at the bottom of the range. I left it with them and accepted the charge for diagnosis. On Monday morning, they said over Fri-Sat they checked, including pressurizing the system, and looking, and they could not find the source of the leak, and told me to come get it. So, I picked it up after they found nothing and replaced nothing, and the area is and has been dry over the last few days since, but, if it leaked before, it will leak again. They told me that if it leaks again, to bring it back and they would check for the source of the leak again at no charge. [how nice! ]
So, again, I know the water pump replacement is an enormous job, but, what about this inlet tube?
p.s. my edge: build date Oct 16, 2007 release date Oct 17, 2007, with warranty start date April 26, 2008 (pdf repair bulletin above states "Replace the water pump inlet tube if the engine build date is on or before Apr 1, 2008")
