Prestone flush kit installation
I want to flush out the cooling system on my 2000 Expedition with the 5.4L, so I bought the prestone flush kit. Prestones manual says one hose comes out of back wall and goes into the water pump. The other hoses goes from back wall into top of engine. Put tee in hose going into top of engine, not water pump.
Well two hoses come out of the wall, with them breaking off into tees. At the tees they have permament clamps. After the tee junctions, one hose goes in to the top of the engine just to the left of the alternator, but that looks like the waterpump. The other hose with all the tees either goes behind the engine or down under the side of the engine.
Can I not use the Prestone fush kit? Is the hose going into the top of the engine to the left of the alternator the waterpump? Where is the waterpump located? Where should I put the flush kit in at?
Thanks for the help!

Welcome to FTE Greg230,
From what I gathered after reading your post that:
The Prestones manual ALSO says:
Your question is:
Answer: Go to an auto parts dealer and ask them " could you please come outside and answer a waterpump related question for me" then ask them:
I don't know the whole answer to this question, but when I need an answer, this is what I do!
DO WHATEVER IT TAKES!

Your Expy may be a little different if it has rear heat, but I'm planning to put that Prestone kit in my F150 in the next couple of days. If nobody has replied, I'll answer your question then.

The hose which goes into the back of the engine is the one you would install the "Prestone T" in. If it has a factory "T", that is probably to your rear heat/AC, and should not affect the flushing action, which is designed to enter the block in the reverse of the normal coolant flow.
However, although I have always used them on previous vehicles, I have decided NOT to install my Prestone flush kit. I may put it in whenever I decide to replace the heater hoses and can re-route them. My reason is that I feel the ignition coils (COP's) are a weakness on the modular V8, and currently this "T" would be right over #4. There's too big a chance that water will leak in operation or in servicing and maybe short out that coil (again!).
Unless your cooling system is really bad, I would recommend that you just add some cleaner, run it around, and rinse and drain it.
