What the heck is this thing and how do I replace it?
I'm leaking coolant and I've finally found out where, but I don't know how to fix it. Behind and to the right of the serpentine belt tensioner (when looking at the engine from the passenger side), is an "L" shaped plastic pipe that apparently has a small crack in it. When the engine gets hot, it starts to spray coolant. I'm not sure if it'* a water pump outlet to the manifold, or what. Along with that, I don't know how to remove and/or replace it. Thanks.
