i bought a wrx coolant tank, the one that sits on the passenger side on the wrx intake manifold. anyway, i was looking at the tubes that stick out from it. the one that protrudes off the cap is overflow, the one in the middle is the feed from the radiator, and the big one, of course is for the feed for the turbo coolant inlet. now what gets me is the bottom one, where does that go to, or where can i tap it to. is it a return line line that i can tap to the heater hose? your help will be much appreciated.

thanks,

joe

 

the one at the bottom of the reservoir connects to the blocks water jacket area i believe. why'd you buy that tank?

i was gathering parts for my turbo kit and accidently bought the wrx radiator. it didnt have the pressure cap on the radiator itself. i finally traded with someone for a brand new gc koyo radiator now. but i still got the coolant tank and i can use it as long as i disable the pressure cap on the radiator. and since i got the td04, i might as well mount it where it is on the wrx manifold with a little diy bracket fabrication.
