Is anyone else's upper radiator hose turning white? had my 4runner for a little over a year now and I have noticed this white powdery surface on the upper radiator hose, I think its coming from the coolant reservoir maybe caused by the vapors? I dont seem to be loosing coolant, the level doesnt seem to be changing, but sometimes I do smell it. I think the intake tube is also starting to turn white.
