Does that make sense? Any help and guidance is appreciated.

the heater return line runs to the factory s10 rad, so its clear why you are wondering what to do when you dont use that piece. but dont fret, there is a plug on the water pump? maybe its the thermostat housing, I dont remember but you take out that plug, its a big allen wrench to take it out, and install a barbed fitting and there you go.

I had to do it on my 1991 s10 4.3, and I cant find the picture because of "photosuckit", but thats exactly what I did.

I finally got a chance to work on the truck. That plug was on the top of the water pump just like you said. I can check that off my list.

Thanks so much.
