Question 2003 Excursion with 94k miles bad water pump??

Just bought a 2003 excursion with 94k miles on it. Took it in to have the coolant, tranny and power steering serviced along with a fan clutch replaced.

Took it out and the thing still got hot when out on the highway and as soon as I hit some hills unloaded.

The dealer is saying its a bad water pump due to the fan clutch being bad.

Im a little concerned since the water pump was replaced around 60k by the previous owner. So my question is how do they know its the water pump and not the oil cooler or some other more serious problem causing my climbing coolant temps?

I have a insight coming in the mail today so I cant give you ECT or EOT's.

Once you start monitoring real temps you can tell forsure, but if they put a water pump on that still had plastic fins its not uncommon for them to break off significantly decreasing the efficiancy. I would also change the Tstat while i was messing with the cooling system. As far as them saying its the water pump do to the clutch fan, I just don't see how they can make that judgement.

How do you know if it is running hot? Gauge on dash? or losing coolant?
