Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the serpentine belt on this 2005 GMC Savanna 2500. It has the 6 liter V8 engine in it. The only tools you're going to need for this is a 10 millimeter and a 15 millimeter socket and ratchet and a flat blade screwdriver.
The first thing that you want to do is remove these two 10 millimeter bolts that hold in your air intake box. Now disconnect the harness to the air intake box. Set it aside. Then, you want to use a flat blade screwdriver to just loosen up this clamp. With the clamp loosened up, you should be able to just lift and pull out your air intake box. Now, using a flat blade screwdriver, loosen up the clamp on this part of the air intake. Once that's loosened up, you should be able to just pull that up and out.
Now, you want to remove your radiator overflow bottle. Just remove the 10 millimeter bolt that holds it in place. Then it will just lift up and pull out and you just want to set that aside. Now that you can see the serpentine belt, you want to use a 15 millimeter socket and ratchet and place it on the tensioner pulley. You just want to push that down and it will loosen up the belt and you'll be able to pull it off the alternator and then pull it off all the other pulleys. Just pull it up and out.
Here's a belt diagram to help you out. It's pretty difficult because it's a little tight in there to film putting the belt back on. Where we'll start is down on the right side with the power steering. Then, we'll put the belt up over the water pump, then down around the crank, and then up on our tensioner, under the idler pulley and then we'll pull the tensioner and get it onto the alternator.
Here, we're going to try to show you the best we can. You can see he's feeding it down over the power steering then up over the water pump. Then, he puts it up over the alternator, and down around the idler pulley. You can't really see it but he's trying to feed it down around the crank and then he's going to pull it up and place it on the tensioner. You can see, we can kind of see he's feeding it down around the crank right there. All that's left is getting it onto that tensioner. Now with the belt in place, you want to put that 15 millimeter socket on the tensioner. You want to push down on that. That will allow you to align the belt on all of the pulleys. Make sure you have it in place. Make sure you have it place and then you just want to tighten the tensioner back up. Just take that part of your intake and put it back down. Put it into position and just use a flat blade screwdriver to tighten up the clamp. Now, you can reinstall your air intake box. You can see there are two holes here. They line up with the two pegs on the van. You just want to feed that down in there. Get it into position. Then using a flat blade screwdriver, you just want to tighten up that clamp where it connects. You can see there, he actually loosened up the part of the intake he put in before this. He loosened it up just so he can angle it and push this part down. Then you just want to tighten both those clamps back up if you have to do that.
We'll just fast forward here. You'll want to put in those 10 millimeter bolts that secure the intake box and reconnect the harness. Then you want to realign your radiator overflow bottle. Put it into position and replace the 10 millimeter bolt in that.
