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 Thanks.

In this video, we're going to show you how to service or replace the serpentine belt on this 2000 Mercury Grand Marquis, same as any 1998 to 2002 Grand Marquis with the 4.6 liter V8. The tool you'll need is a 3/8 inch drive ratchet and also a piece of pipe might help for some extra leverage.

It's pretty easy. Right here is your tensioner. Take a 3/8 inch drive ratchet handle. Work it right into your tensioner. If you only have a short handle, use a nice big piece of pipe. It helps you to move the belt easier. Then you can pull it off there. Actually, you can see that my tensioner's in need of replacement because it's not moving freely. When it does that you want to be careful because it could snap back at any minute. Let's take our belt off and out. Let's take our belt off and out.

Before we show you how to put the belt back on you can see we put a new tensioner on the car. If you want to see how we did that, you can just check out our other videos for the Mercury Grand Marquis belt tensioner replacement.

Take a loop, and you want to put it down, all the way down, onto your A/C pulley which is the one furthest down. Then you want to come up, around your tensioner here and then around your water pump and down to your crank pulley, and then across. Over here is your power steering pulley. Then you should be able to kind of pull it a little bit tight and get it up on top of this idler pulley here. Now it's all preliminarily routed. Just make sure it's in the grooves in these pulleys. It looks like it's good. Now take a 3/8 inch ratchet, put it on there. Put on the pipe just to make it nice and easy. Pull this over, and while you do that, pull this up, and on top of your alternator. Then make sure that everything is pushed in. Your tensioner will go back. Make a quick check. It's not quite on my pulley down there. It's around the crank fine. I'm just going to put this back in. Take the tension off a little bit, and push it onto this pulley way down here. Now it's good. You're all set.
