A common problem I guess. I went to the dealers because I thought maybe they'd be the only one with the part. While tearing it apart I found out they only gave me one elbow. I found them at the Napa down the road. Cheaper for the pair of them instead of one. Chevy dealers are a ripoff.
I noticed a greenish sludge splattered on the underside of my hood, above where the serpentine belt comes up in the back of the engine compartment. Turns out that GM uses two L-shaped elbow tubes to pipe coolant between the intake manifold and water pump. There's two of them, made of plastic, and the plastic became brittle over time, started leaking onto the serpentine belt, which caused it to splatter up onto the hood.
The parts are pretty cheap, here's the link, cost about $10:
Replacing them is a bit tricky. You'll need to take off the belt, alternator, and idler, but if you at least walk in to the mechanic with these in hand, it's about an hour job to fix -- he should only charge you the labor, around $100 for the hour is the going rate these days.
