In this video we'll show you how to remove and reinstall the serpentine belt on this '98 Explorer with a 4.0 liter EFI motor, the same as many Explorers with this motor. The tools you'll need are an 8 millimeter wrench, a flat-blade screwdriver and a 3/8ths drive ratchet handle. Disconnect the negative battery cable with an 8 mm or 5/16ths wrench. You're going to want to pull your intake hose back which is fairly easy. You want to loosen up this clamp here. Then you want to unclamp the air filter box. Then you're going to pull that off of your throttle body and lift up. Then you can just kind of lift this up and throw it away. Now to remove the belt, right here is your belt tensioner. You want to take a 3/8 drive ratchet handle and put it in this square hole right in the tensioner. I'll put my wrench down in there and push down. I can see the belt loosen up.

Then you slide it right off of the eyelet pulley. Bring your wrench back up. Then you can just take the belt off all of the components. Reach down and flip it off of the crank shaft. It comes up now. What you want to check on the belt is you want to check the back side. You always see quite a bit of cracking on the groove side. What you want to check is the outside. You especially want to check where the belt is seamed which hopefully like on this belt you can't find. Wherever the belt is seamed is usually where it wears out first. Now I'll put the belt back on. Very important, here's your belt diagram. It shows how the belt is routed. What we want to do is make a little loop and work it around the crank shaft here first. Then we'll work around everything else. Make that loop. You kind of want to make it tight. Pass the belt under the shaft of the fan a little bit if you can just get it into your other hand. You want to get it up under the crank shaft or around the whole crank shaft maybe on top. The belt goes up and over the water pump and around the power steering pump and AC compressor, over the alternator and into the tensioner. The idea is you're going to press on it here. Make sure everything's lined up good and well. Then push your tensioner down and in with the wrench. Then slide the belt underneath the idler. You're all set. Push the air hose back over. Push it right there. Push it back in here. There are three tabs over here. Just make sure they go into the right slots. Clip it back on. Make sure that's pushed on there well. Tighten your clamp back up. Make sure all these connections are still good. You're all set.
