Need to know how to adjust serpentine belt, please show diagram. 6 cyl engine.


Really don't need a diagram. Loosen the slide bolts on the power steering pump. loosen or tighten the pump by turning the jack screw (long transverse bolt) under the pump. Once the belt is tightened up, lock down the slide bolts and you are finished.

How to tighten serpentine belt for 2003 Monte Carlo 3.8L


the belt is self adjusted by a spring loaded automatic belt tensioner, if the belt is noisy or seems loose either the belt size is wrong (if it was replaced recently) or the tensioner is defective or one of the belt idler pulleys is defective.

Re install a serpentine belt on a 94 chrysler lebaron 3.0L


There should be a diagram attached to the car near where the belt goes showing how the belt is to run through the pulleys.
Newer vehicles have a tension pulley which is a pulley on a spring loaded arm that keeps the belt tight.

First run the belt on all the other pulleys and then use a wrench to hold the tension pulley back while you slip the belt on.

Older cars do not have a tension pulley and you had to usually loosen something like the alternator a little bit to get it on.

first thing you need to do is get a new belt that belt dressing just destroyed that belt that stuff is no good then get a new belt tensioner clean all the pullys with some brake clean then install the belt tensioner and belt if its still sqealing there maybe a pully making the noise to check that when you have the belt off spin them by hand and listen to them and feel for any play in the bearings

Replacing a serpentine belt


Don't have a chart, video, or diagram available at the moment. Can offer you generic advice.

1.Somewhere in the middle of that serpentine belt, that is wrapped around all those pulleys, is an Idler tensioner Pulley. All this pulley does, is put tension on that serpentine belt. Usually located somewhere in the middle.

The Idler tensioner Pulley will be on a bracket. It will be on the end of the bracket. The bracket usually has a 1/2 inch square hole in it. This is used for a tool, that resembles a 1/2 inch breaker bar.
-> I, use a 1/2 inch breaker bar.
The 1/2 inch breaker bar is inserted into this square hole, and the bracket is pulled to one side.
This pulls the tensioner pulley away from the serpentine belt, allowing the belt to have slack, and then the belt is slipped off of one of those pulleys. Release the pressure slowly, remove the tool. Then the serpentine belt is removed all the way.

(The Idler tensioner pulley bracket, can only be moved in one direction, to take pressure off of the serpentine belt. The direction opposite, of it putting pressure on the serpentine belt.

The spring used to put pressure is Very strong. This is also an area, where you can easily slip, cutting your knuckles, or fingers, or hand, on sharp objects. Use caution, you may want to wear a glove, or gloves!)

Then the new serpentine belt is wound around the pulleys in the correct pattern, the Idler Tensioner Pulley is once again pulled to the side, and the last of the serpentine belt is slid into place. Then you slowly release the tensioner pulley, and it puts pressure on the serpentine belt once more.

Make sure the serpentine belt is in the grooves of the pulleys, and is wound around in the correct pattern.

On the car hood inside, or on the radiator support, or perhaps on the inner fender well, or in the Owners Manual, it should show the correct pattern for installing the serpentine belt.

2000 f250 diesel, how do you release the tension on the belt?


There is a tensioner idler somewhere on the engine. Use a wrench and rotate the bolt in the center so that the pulley moves away from the belt, then use the other hand to slide the serpentine belt out from under the idler.
Slowly release the tensioner.

How to put on the serpentine belt for a 1994 plymouth grand


Well, first of all you don't "loosen" the tensioner. Tighten that back up. Route the belt as it should go. Put a 15mm open-end or box end wrench on tensioner bolt (in the middle of tensioner.) To make this really easy, I use a "cheater" (a pipe large enough in diameter to go over wrench) to give added leverage to pull down tensioner far enough to slide belt over. Personally, I route the belt over everything except the idler pulley then pull down on the tensioner far enough to slip the belt on the idler. Because of the small cleareance, trying to use a socket on this bolt is almost impossible however, the previous is the method I've learned to be the most efficient.

Can't quite slip serpentine belt on


Try using a 1/2 inch socket on your heaviest socket wrench. Put it on the nut on the idler pulley and push the idler back to allow you to slip on the belt.
