I am going to be buying a ford expedition this summer and I am wondering what kind of results any of you guys have gotten with your 2 piece underdrive pulley set. I will be getting a used 1997 Expy, 5.4 with a towing package. I will be commuting to school, so I will be very interested in gas mileage gains. Anyone have bad experiences with underdrive pulleys on there Expy? Where did you guys buy your 2 piece underdrive pulley sets from? Would you combine electric fans with an underdrive pulley set?

Sorry guys, but I'm a newbie to the Expy world. I have the same one that you're planning on buying, and my gas milage sucks. What are these underdrive pulleys? I'm very curious as to what they are, and how they can improve my milage. If anyone has any links or websites with more info, it would be really appriciated!

Check HERE for a good discussion on the pully issue. They have mixed reviews. Sexpeditionsprt has tried them I believe and may hop in here and lend you his experience.

Everyone says the electric fans are awesome and a worthwhile mod if you have $400. B-Man just put them in his truck and gave an excellent walk through of the process HERE. Hope this helps.
