Well, I broke the threads that connect my thermostat neck piece, and replaced the whole unit last night with one off a NA because it was just laying around, I didnt notice the NA one didnt have a turbo water return fitting. I am thinking about just T-ing into the heater line when it comes off the bottom of the radiator and jumping in there, but I figure the idea of the water return hitting the pump is for the water to go up to the radiator because its hot water, I dont think this will affect temps much, but I wanted to see what you guys thought.





So its a S4 NA water pump assembly on a S4 Turbo II...where to dump the turbo water return is the question.

There is a Cast "boss" on the NA Housing, Drill and tap this with a 3/8" NPT (?) tep and tread in a barbed fitting, VIOLA~ instant water return

A cast boss? I dunno what that means. Or where that would be? or what a boss is. But I will look on it..



Thanks

Also, is it possible to just block off the coolant line on the back of the engine and then route the turbo water in thru the back of the water neck.

I forsee we are going to have to do a lot of work.......

yep, you're gonna have a bunch of little things to straighten out

You can return coolant back through the heater core return line.

Kind of a hack, but, "Get R dun" for now.

i'll have to post a pic for you.

Damn you mike, change your avatar picture lol

Well I have it T'd into the line that goes from the back of my engine to the coolant filler neck back area, then low and behold the son of a bitch started leaking under the alternator........son of a bitch car...
