2005 WRX - Just replaced the radiator, which had a nice big crack on top, only to still have the same sickly sweet smell. Pressure tested it and found it to be a pinhole leak on the left side of the engine in a rubber hose. This hose is next to the exhaust manifold. I have no clue what it goes to, my service manual doesn't seem to have it, or i can't seem to find it. The hose is a relatively short rubber hose that clamps on to larger metal tubes at the top and bottom. I don't know how long it is going to last and I do not want it to fail on me mid-drive. It is in a tight spot which seems to be blocked by the frame on the bottom. You would need the hands of a small Japanese boy to get to it.

Any idea as to what it is and/or the easiest way to get that bugger off?

Thanks
