Can we talk about the 5.0L water pump

Went by the Bellevue, WA Jag dealer today to get some parts, and there was a 2010 XK up in the shop in the midst of an engine swap due to water pump failure. Tech said the guy must've driven it a while because it had coolant in the oil due to overheat.
<shrugs> Another data point. What would be interesting is to have this correlated with XJs and Range Rovers using the 5L motor -- are they having failures too? If not, maybe we have a problem unique to the packaging in the XKs.

I had my local jaguar dealership look up the numbers given by the poster that listed hoses and tubes saying that was the fix:
AJ813565 is a HOSE description listed at a price of 36.82
C2Z28467 is a TUBE description listed at a price of 36.57
Dealer prices.
Now then nobody I know knows for sure if this is exactly the fix?!? Is the latest water pump required to use these tubes/hoses??? Is it advised to update/replace all parts at once?? It is advised to do so if you have not had a low coolant warning but yet your water pump number, as mine as, has been superceded!?!?

Even if this information is correct, the replacement is going to be entirely at the owner's cost. This certainly will not be covered under any factory or extended warranty unless there is a failure of the part.

I just had my local dealer look these up as I'm up for scheduled maintenance. Parts guy says that these are for normally aspirated 5.0L for a VIN range after mine (mine is a VERY early 10). Does that mean we have different piping immidiately after the water pump between XK and XKRs?

So... XK pumps different from XKRs. We should start tracking failures for each to see where the design flaw is.
From the parts guy himself:
THE #’S YOU SUPPLIED ARE FOR THE WATER RAIL AND T-STAT, SUPERCHARGED CARS HAVE AN AUX PUMP AND RADIATOR FOR THE SUPERCHARGER, THE WATER PUMPS FOR THE ENGINE ARE A DIFFERENT PUMP.

Wow, A very long read, and disappointing to hear of a cooling system failing on the new 5.0 design. Odd the 4.2 has not gotten a bad pump reputation (Just thermostat).
So my question is if the internal seal is allowing fluids to weep by and damage a bearing, could you switch to waterless coolant and prevent the weepage?
My thought is without pressure (waterless does not pressurize the cooling system), the seal should hold far longer.
Might be worth review for this scarey problem.
Food for thought.

I'm not 100% certain, but there is a chance that my coolant level in the reservoir is ever so slightly lower after 2500 miles of driving. I'm not totally certain how high it was topped off to begin with, but now If anything, we are talking about a few ounces. I know if it gets any lower. It still reads full on the side when cold. If so, I will address my local dealer before bringing it in. They don't replace water pumps unless there is a significant leak. I'll try both of my nearest dealerships to see who has the more favorable response.
