I'm trying to locate an idler pulley for my car, but I can't find one anywhere. All I can find is the pulley that goes on the tensioner. What's more, I have no idea how to remove this one because of its strange design. Here's the closest (still wrong) diagram of my engine I could find. My water pump is where the power steering pump is labeled (mine has electronic power steering), and my idler pulley is where the water pump is labeled.
It's difficult to get a good picture, so I hope this is worth at least a hundred words. It has no hex bolt or anything to grab in the center, but it is surrounded by four bolts. It needs to be replaced, but I'm stumped.
