frustrated2

Thank you all for the input and advice. I didn't have the right size heater hose so I went with some extra fuel line that I had.

'95 EJ18, Manual, 210K I was replacing my radiator when I realized that the new one has two nipples on the bottom, facing the engine bay, that my old one does not have... at all... not even holes that have been plugged. What are these for? Can i just run some 3/8" heater hose to form a closed loop? Am I missing something here?

I had a very similar situation. Follow this link to my posting: http://www.ultimatesubaru.org/forum/topic/151500-pinhole-in-pipe-leading-to-coolant-bypass-hose/ It may seem daunting but the repair is very easily accomplished. If you cannot find a replacement pipe, cutting out the damaged portion and running heater hose as a bridge may be your fix (Bushwick's advice on my post), which in my opinion is better than JB weld. If you go with the JB weld option, make sure your area is cleaned thoroughly and dry. If you don't have it dry you may need to go with JB Water Weld (8277).

Wouldn't have been possible without the advice and guidance from this message board. It is such a good feeling going from dead in the driveway to back on the road as a daily-driver.

Thank you all! Reporting back with an update: Success was achieved. (Gloyale, you were right on with that 17mm nut, ugh) Had to rush to get everything back together before the blizzard, but got it done and did it right. I'm sending out internet fist-bumps to you all... thanks again!

Awesome info. Thank you! I didn't see that you could move PS pump out of the way without disconnecting the lines. I will order coolant pipe o-rings and intake manifold gaskets. I have plenty of heater hose on hand and hose clamps. Anything I'm missing? Maybe PS pump gasket or o-ring (haven't looked at that part of the FSM yet) (heartless: I'll be in touch if I hit a snag and need some guidance)

So, I found one and the initial look over seems OK. I want to take a steel brush over two spots to see closer, but I'm hopeful. Good experience at the yard but not 100% simulation as the engine had many parts ripped off already. took me about 1.5 hours; i'm thinking with my car it will be 2.5 to 3 hours start to finish. One thing I learned is that the power steering has to be disconnected like the FSM says; there's just no getting around it (can PS fluid be recycled back into the system if I manage to keep it clean?. Same with the main crossover coolant pipe; the way the pipe I'm working with is shaped it is impossible to "thread" it through underneath the main coolant crossover. I may be able to get away with leaving the A/C pully on, we'll see.

I just called my local u-pull-it and they have a '93 legacy in the lot. According to the parts catalog provided above, the '93 pipe is the same as mine ('95). They couldn't tell me what is in it or in what condition - the whole engine could be gone or this pipe could be shot. I'm going to take a look this afternoon. If it is there I'll extract it; worse case is the pipe is shot but at least I familiarized myself with the process. heartless: I'll update this thread so if I get lucky and get a pipe you won't have to look.

heartless: if you do have this on-hand, it would be a great turn of events for me. Please let me know. Thanks!

**Just now saw the link you provided for the part number. Thank you! Thanks Bushwick, thanks Fairtax4me. Much to digest and think over. To physically get at this area to do any patching, cutting, etc without removing the manifold seems impossible. I can currently access the pinhole with a 12" hemostat with a wad of shop towel just barely to dry and wipe the area clean. The only way to do so is going in at an angle from rear view mirror to driver's side CV joint, and with no wiggle room. Can't even fit my hand in there. I think removal of the manifold is the key. I wish it were not. The constant air in the system is explained and what I suspected was confirmed. I am also seeing the quick spike in the temp gauge as Bushwick mentioned. It all makes sense now. For u-pull-it practice and procurement, which years and models would work for a direct fit? If I don't score one and have to go the stealership route, what are the part numbers? Or do you think I can just show the FSM diagram I that have?

Sorry about that. I posted it on Imgur too. It is a page out of the Cooling section of the FSM. Link: http://i.imgur.com/4UbqZ79.png

1995 EJ22, 215K miles. Hopefully the picture (pdf) loads correctly for reference. I discovered a pinhole in the pipe going to the bypass hose. What input can you give me? What would it take for me to replace this pipe myself and what other parts should be replaced while I'm in there? Seems a bit daunting to me seeing that I have never messed with the manifold before. I have done my own timing belt & water pump but that is the extent of my wrenching. If anybody knows the part number or what this pipe is called, please let me know.
