The right parts installed correctly that's going to save you time and money. Thank you and enjoy the video.
In this video, we're going to show you how to replace the idler pulley for you serpentine belt on this '98 explorer. The procedure's the same for a lot of explorers with both the V6 and V8 engines. The tools you'll need are 8mm wrench, flat blade screwdriver, 3/8 drive ratchet handle, and a 15mm socket ratchet and handle. Disconnect the negative battery cable with an 8mm or 5/16 wrench. You're going to want to pull your intake hose back, which is fairly easy. You're going to loosen up this clamp here and then you want to unclamp your air filter box. Pull that off of your throttle body. Pull this up and you can flip this up and move it away. Now to remove the belt, right here is your belt tensioner and you want to take a 3/8 drive ratchet handle and it is square hole right in the tensioner. Put my wrench down in there and push down and you can the belt loosen up and slide it right off of the idler pulley and let your wrench back up, and you can take the belt off of all the components. Reach down and lift it off of the crank shaft and it comes up and off.
This right here is your idler pulley. Once you get your belt off you can actually test it, just try to shake it back and forth and spin it and you shouldn't hear any noise. If you hear noise or you feel play you'll want to replace it. This one actually is in good shape so we'll put it right back on. You got your 15mm socket on there, and a little trick for extra leverage, I put a larger wrench down around my ratchet handle and I pull nice and easy on the big wrench and that gives me the extra leverage and keeps my hands out of this area so they don't get cut up. Once it's loose, I can just use my ratchet. Then you do need to twist this little lock washer off. The bolt comes out and see there's little bushing right here. Here's a new pulley from 1AAuto, the original pulley. You can see they're both the same. We tested this one and it was still in good shape so I'll put that one back on. It's pretty easy. You put the bolt through and make sure this washer gets on the back, hold everything together, put it right back into place.
I'm going to use the same trick with my big wrench, tighten up and 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 and then we'll work around everything else. Make that loop and make it tight and pass the belt under the shaft of the fan a little bit, get it into your other hand, get it up under the crank shaft and around the whole crank shaft and the top. Take the belt up and over the water pump, around the power steering pump and ac compressor, over the alternator and into the tensioner, press on it here. Make sure everything's lined up well. Push your tensioner down and in with your wrench then slide the belt underneath the idler and then you're all set. Put the air hose back over. Push it on the there, push it back in here. Then the three tabs right here, 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.
