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 I'm going to show you how to replace a serpentine belt. This 2005 Chevy Silverado has the 4.3 Liter V6 so this procedure is the same for any Silverado or Sierra that has the 4.3 Liter V6 from 1999 through 2007.

The serpentine belt is pretty easy. First, make sure you find your belt diagram. This is the 4.3 Liter V6 so there's the diagram and it matches up with what's in the engine compartment. Removing the belt is pretty easy. Put a 3/8 inch drive ratchet right in here. Pull on that. See that loosens the belt. Move it from the idler pulley up top. Release that slowly. Then you pull your belt right off.

To put the belt on, you want to follow the pattern. You can't really see this but I'm going to go down around the crank pulley first, then I bring this up and around the water pump here. Then it goes from the water pump down to the power steering pulley here, up to the A/C pulley, across the tensioner and the alternator. I'm just going to reach down and make sure everything is pretty much on the way it should be. Now, you can press down when you see the belt starts to tighten up as you try and press it on to the idler here. Then we take our wrench, put it in, press down. That gives us the slack to put the belt right in here. Then just check. Make sure it's on all the pulleys correctly. It's in the grooves. It's actually not quite on there correctly, so pull it off here. Okay, the new belt is on.
