I noticed coolant dripping from my 1992 Legacy (2.2, non turbo, manual trans) this weekend. Turns out the leak is where the small (about 8 mm id) hose that, I believe, delivers coolant to the throttle body attaches to the cast aluminum water pipe that runs over the top of the engine block. I had to remove the intake manifold and everything that is attached to it to access this pipe. I then removed it from the block. There is a port in the aluminum water pipe into which a short length of copper (brass?) tube was apparently pressed. The little hose then is installed onto the copper tube. The problem is that the little copper tube seems to have deteriorated and fallen right out of the aluminum pipe. What I am wondering is if I can repair this relatively easily or if I am better off just getting a whole replacement aluminum water pipe off a doner car.
If my description makes sense to anyone, has anyone ever dealt with this? Is the little copper tube available from Subaru? Is it a press fit into the aluminum pipe? Any other comments?
