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 a serpentine belt replacement. This is a 2008 Dodge Ram. It has the 5.7 liter Hemi V8, but this process is the same for many vehicles. The only thing you'll need is a 3/8" drive ratchet.

Here's your serpentine belt. Before removing, you'll want to make sure that you have the diagram for it, usually located under the hood or on the radiator support of your vehicle. We weren't able to find one on our truck, so for our information, and to help you out, you can see, here's a still photo of our belt properly routed. This is obviously just on this 5.7 liter Hemi V8. We do reference back to this every once in a while in the video to show you better how it routes.

Using the drive from the 3/8" ratchet, you'll insert it into the slot on the tensioner, remove the tension from the belt, and take it off the pulley. Remove your serpentine belt from your accessory pulleys.

To reinstall your serpentine belt, loop around your crank shaft pulley, bring the top side over the water pump pulley, under the power steering pump pulley, over the A/C compressor, under your upper idler pulley, to the other side, go over your lower idler pulley and around your tensioner.

Using your 3/8"? drive ratchet, remove the tension from the tensioner pulley and install the remainder of your belt over your alternator pulley.

Ensure that your belt is properly seated around the pulleys and installed in the correct path before starting your vehicle.
