as recommended by SuperDiesel...
I'll try to find a picture for you...
heard its a PITA, gotta remove A/C pump, coolant line, PCV line, then remove the 3 torx-25 screws holding it in without dropping them into the valley.
I'll try to find a picture for you...

Tools needed:
Torx T-25 bit in 1/4 drive and 2 inch extension.
12mm sockets
15mm sockets
8mm hex bit
10mm sockets and wrenches
various small screw drivers
Getting started:
Disconnect the negatives on both batteries
Pull off the intake hose
Drain the coolant out from the radiator, there is a little drain bolt that can be opened up so that the coolant can be drained.
note:
You only want to drain enough to empty the thermostat housing. about a gallon would be enough to keep the coolant from going all over the place when you crap open the thermostat housing.
====================================
Next thing would be to remove the AC compressor
when you unbolt the AC compressor just lay it on over to the passenger side of the engine.
=====================================
The next step would be to remove the radiator hose coming from top of the radiator to the thermostat housing.
========================================
After removing the hose you will have to get the thermostat housing off. You might have to move the big electrical wire connectors out the way a little bit to get access to the bolt that's holding the support bracket that's part of the thermostat housing down
========================================
after that you can now work on getting the actual bolts on the thermostat housing. there are 4 of them that need to be removed to pull the housing off.
once its off you can lay it out the way or just disconnect the hose on there thats going to the turbo.
====================================
Now you can get to work on getting the wire harness out of the way.
once you work your way disconnecting wires form the driver side to past the turbo you then can lay the wire harness over to the side.
After doing that you can then remove the turbocharger inlet horn. there are 3 10mm bolts holding it on, a flex hear ratchet head wrench works nice in this area.

Now you should have a clear view of the FCA from up top.
There is two rubber hoses going to the cp3 pump, remove them to get better access to the FCA with your torx bit.
Here is a side view of it. (note this is a lbz fca on a lb7 cp3)
Heres a top view of it
There is 3 T-25 torx bits holding the FCA to the cp3. Be careful when removing them make sure that the bit is stuck firmly in the bolt before trying to remove it. A nice trick t do it put some glue on the bit so that when you take it out you dont loose it into the abyss that is also known as the valley of the engine. These bolts are a litte hard to get out but it just takes time a patience. If you happen to get some dirt in the hole where the fca used to be, turn the engine over a few times so the cpe can flush the fuel out that hole and taking the dirt with it.
when finished swapping out re-assemble the truck

wow, that looks like a bit more involved than I dare to go. I will buy the part and let my trusted dealer do it.....but first I will try the tranny fluid to see if I can buy some time.
Thanks Paul for the info.I really do appreciate it.

Sfc,
You can do it. I did it and all it takes is some time. I actually had to pull my whole CP3 out to get the fpr out because the screws were pretty siezed up but its just nuts and bolts. You can getter whipped. There is a thread somewhere that I was asking questions in and Vinny (Durallymax) listed the best/cheapest places to buy the FPR. I got mine from Merchant tho

just don't use it too often... you could coke up the injector tips...
lets hope this one (or occasional) dose does the trick...
