It will normally not leak while running, so, yes, it is the water pump.

It will most likely be leaking from one of two areas, the first, weep hole at the center of the pump, the second is from the pipe coming off on the bottom side ( drivers side). there is a cheesy O ring that leaks once in a while.

I asked BTS and Brian clued me in on getting it from O'riley. New unit, lifetime warranty. So far, no problems.

I tried once to share with someone else,but I wasnt clear enough. This is a very simple job, but you have to remove the fan cover, you have to remove the fan. There is no short cut, but the job itself is a breeze, just time consuming. To remove the fan, you will need a strap wrench ( for the pulley ) and either a Fan wrench ( free rental at parts stores normally, they just want a deposit ) or a large adjustable. Just know, there are no short cuts, but it is a very simple job!!

Just like Pat said - easily done just time consuming. Did mine last year, could never catch the bugger leaking - she would just leave a spot once in a while. Might as well change the thermostat while you have it apart and consider the Billet T-Stat housing from Dieselsite.com since the stocker is easily bent.

Definitely sounds like your water pump is the issue. You can ussually see some rust/discoloration from the leak near the pulley, tough to see - just use a flashlight.

As mentioned above,not a hard job to do.
A air chisel makes short work of the fan clutch !
(or a long chisel and bfh)

Don't do the 203 stat! Not worth it... Go get a ford OEM stat. Hotter coolant means hotter oil.. not necessarily a good thing.

The reason you don't see it leaking while you are driving is the fan dries it off there pretty quick. But I would ispect all your hoses first and even the thermostat housing/gasket.. those can leak easily.

Get the waterpump from Northern Tool. They are only like 75-80 bucks and be done with it. It can be a pain to install... especially removing the fan off there.

Good clarification, That's what I did - used a new OEM thermostat.

I'm with Steve on this one.

Back in January when I was down in Holtville at JW's shop, both John and Jody said they didn't like the oil temps generated because of the 203 stats.

I plan on doing a backflush and ELC fill for my truck, and will probably change the water pump at the same time (preventive maintenance) and when I do, I'll add the Deiselsite billet housing, but I'm gonna stick with the stock thermo.

I hafta get another stock thermo for the Excursion too because I wanna pull the 203 stat I put in there a couple years ago. Gonna have to give Ed a call!

Now i,m wondering if I should take out my 203* stat now, my oil temps were 233* degrees at operating temps on a 80* day..? Thats where I got my oil temp reading from, my cluster test I did with my trip reset button.

That is getting warm... seems a little hot. I would check to make sure that thermostat is actually opening. Mine was a bad one and would crack open at 220 degrees. It is real easy to check, one way after the truck has reached operating temps... grab that top hose to the radiator and squeeze it if it is real squishy then it is open.. if it is hard then it isn't open. Or just pull the thermostat and stick it in a pot on the stove and stick a thermometer in there...

I put a new stock 195* thermostat back in last weekend. Jody said my EOT was a bit too warm to his liking when he live tuned my truck at RRE. I data logged my EOT's before my Stealth Pump install and saw 220*. I haven't done another data log, yet. But, I will after my chip arrives on Monday. I will post my new ICP's and EOT's after the chip is installed and a new AE data log is done.
