    Coolant hose to turbo - slow leak?

    Anyone noticed the coolant hose from the radiator cap housing to the top of the turbo (the rear hose of the three hoses surrounding the radiator cap; the other two go off toward the front/center of the car, while the hose to the turbo goes to the rear and down) seeps coolant? Or so it seems? I can't tell really.

    I see coolant remnants on the bottom surface of the hose itself, where it meets the metal nipple, and along the nipple and the top of the radiator cap housing (the mini "tank" on which the rad cap and the three hose nipples are located).

    Odd thing is, the system has been pressure tested and checks out fine as of last week, and I can't replicate the leak - but it was coolant I saw, greenish white. I whiped it off and ran the car 30 minutes, no more juice - but I still suspect the hose and/or spring-type stock hose clamp.

    If it gives me more crap I'll put a screw-type, real hose clamp on it - but has anyone seen this happen? Or is someone else's work confusing me (I just had the cruise throttle cable recall done, and maybe the tech pulled the rad cap to check coolant level, spilling a little etc., or maybe I'm just plain nuts?).

    Before you think "not on my car" look closely for a white residue around the bottom of any of the three nipples on the rad cap platform...

    Answering my own question - yes, it leaks. A small leak will look like white/green hue on the hose edge or the nipple.

    I switched to a screw-type clamp. Couldn't find the (better) T-bar clamps around. All's well.

    Check your turbo supply hose.
