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 be working with our 2001 Ford Ranger 4.0 V6. We're going to show you how to remove, inspect and either reinstall or replace your Serpentine accessory belt. If you like this information, please click subscribe. We have a ton more information on this truck as well as many other makes and models. If you want these parts for your vehicle, they're available from 1AAuto.com.
The items you'll need for this repair include a 7mm, 10mm, 13mm sockets, ratchet, socket extension, 3/8 drive ratchet, Phillips screwdriver, and flat blade screwdriver.
Before removing any components of the serpentine belt, be sure to check that your vehicle has a belt diagram somewhere on it. Ours is still present on the upper radiator support, but you may also find them under the hood or in your owner's manual. If you don't have one available, simply look at the belt and the path around the pulleys, and draw yourself a little diagram of where everything goes to ensure that everything is installed correctly and turns in the correct direction.
We're going to disconnect our battery for safety to make sure that our engine can't turn over while we have our hands inside of the belt, because all those components will move if the engine cranks. The battery is located on the front driver side of the engine bay on this truck. We're going to use a 10mm socket and ratchet, or you can use a wrench to remove the clamp on the ground side of the battery.
Loosen the clamp, wiggle it off of the terminal, and tuck it somewhere down to the side where it won't accidentally come back and complete the circuit. We're going to remove this cover over the throttle body. Use a small Phillip's head screwdriver to remove these two screws, and a 7 millimeter socket and ratchet for the bolt in the back. Remove the cover from the intake.
We're going to use a flat blade screwdriver to loosen these two screw type clamps on our intake tube. Then wiggle the tube off of the MAF sensor and the throttle body, and remove it from the vehicle. You'll also have to remove this breather line from the back, so we'll remove the intake tube from the throttle body, and the MAF. Pull it straight off the breather, and remove it from the vehicle.
Your serpentine belt tensioner is located on the passenger side of the engine just below the alternator. At the bottom, there's a 3/8ths square drive, which we'll use the end of a 3/8ths drive ratchet for. Install it into the drive the same way you would install a socket onto to the ratchet, and pivot counterclockwise to remove tension. We'll then remove our belt. You can work it all off from one side. Carefully remove your pressure against the belt tensioner to be sure that the ratchet isn't going to get stuck against anything or that your hand won't be caught in between. Remove the ratchet. Finish removing your Serpentine belt from the vehicle.
Turn your belt inside out and inspect the ribbed side for any cracking, dry rot, any kinds of tears or burnt-looking rubber. If you have anything that looks like that, you should be replacing your belt. Ours looks okay, so we can reinstall it and get some more mileage out of it. We're going to loop our belt here, feed it down, and hook it around the crank shaft to start. We're coming in from the passenger side here, because that's how it's going to be easiest to route our belt. Once we're hooked around the crank, we'll run the smooth part of our belt over the water pump to the driver side. We'll go under our A/C compressor at the far end.
Be sure that that's seated in fully. We'll go over our power steering pump at the top here. We'll run the other side of the belt coming off of our crank around the tensioner. That's from underneath so the ribbed part will also be touching the tensioner the same way it comes out from under the crank. The ribbed portion will go again over the top of our alternator.
Now, when we release tension, we can push down in the middle and go underneath our smooth idler pulley. We'll reinstall our ratchet into the tensioner, turn it counterclockwise again, try to get as much swing here so we can pull it over pretty far. Go underneath the smooth pulley. Inspect one more time for proper belt path and that you are not hooked on the edge of any pulleys. Release the tension and your belt's on.
Reinstall the breather line in both ends of the intake tube to the throttle body and the air box. Tighten down the clamps with a flat blade screwdriver. Reinstall the engine cover and we'll tighten down the front two screws with a Phillips head screwdriver and the rear with a 7mm socket. Reconnect the negative terminal, tighten the clamp back up with a 10mm socket and ratchet or a wrench. Ensure your connection is tight and you're ready to go.
