Exact replacement for my F150 2008 4.2L. Very good price compared to my Ford dealer. I thought maybe that's where the creaking comes from, but it wasn't. It can be hard to tell where it's coming from, but in my case it turned out to be a new belt that I had installed. I put my old belt back on and that fixed it. (Update) Noise back so I ordered the original Motorcraft belt. Worse! I ordered the Gatorback belt that everyone loves on YouTube. No more noise! Now I know why it's called Quiet!
