Swapping S5 N/a water pump for S4 N/a water pump.
 

given I have the whole housing/pump/t-stat/filler neck can I swap them? My 89 GTU just starting pissing coolant from the lower weep hole and I got a great S4 pump sitting at home off of my 87. What problems will I encounter?

if you have the whole housing it should swap right over, i have an s4 housing on my s5 block in my s4 car...

P.S. Dont loose the shims!

shims?

spacers shims...without them the housing goes in on an angle

on my t2 you need the front cover too. i tried the s4t2 on my s5 front cover and its shaped a little differently. i have all the stuff at home for a s4 t2. that im going to sell eventually. wont be able to get it until thanksgiving though.

S4 -> s5 you have to change the front cover. I'm pretty sure the same is true for vice versa.

damnit I guess, I don't want to swap front covers just to save 50 bucks. Thanks guys.

You just need to do a little grinding; I have put an s5 waterpump assemble on an s4.

interesting :) I got a dremel.....;)
