Video on how to replace the serpentine belt, the belt tensioner, and both idler pulleys on a 1997 to 2004 ford pickup f150 with the 4.2 engine.COMPLETE VIDEO
The first digit is the amount of ribs the belt has. So if you need a 4 rib belt, the first digit is a 4, if you need a 6, it’s a 6, and so on. And all the digits after the PK are the length of the belt in millimeters. Going back to the example we gave, a 6PK1234 belt will be a six rib belt with a length of 1234mm.

The serpentine belt on a Jeep TJ can be replaced by following these steps: 1. Remove the old belt by loosening the tensioner pulley and sliding the belt off. 2. Clean the pulley surfaces and install the new belt. 3. Route the new belt around all the pulleys except the tensioner pulley. 4.

In most cases, it’s the serpentine belt that causes the noise. However, inspect the pulleys as they tend to squeak with time. Tighten the Belt. Locate the tensioner and loosen the bolt to move it so you can tighten the drive belt. Do this carefully to avoid dislocating the entire system. Ensure the belt has less tension when tightening the The belt tensioner on the Nissan 4.0L V6 (VQ40) found in the Nissan Frontier (2005 and up), Pathfinder (2005-2011), and Xterra (2005 and up) does not properly tension the belt over time, which is what causes the annoying squeaking noise because the belt is slipping in cold/damp conditions. I highly recommend also replacing your serpentine belt
What happens if serpentine belt is to tight? If the belt is too tight, it will cause excessive side loads and overheat the bearings. This in turn causes noise, decreased output and even the seizing of the alternator. If the belt is too loose, it will cause the alternator to slip. This slipping can cause the alternator and the battery to work
Depending on your engine, the serpentine belt replacement cost is between $100 and $200. Most vehicles do not need a special serpentine belt tool, but rather a 1/2" breaker bar and a socket on the serpentine belt tensioner to relieve the tension from the belt.

I created a very crude belt routing diagram to assist you in properly installing the new belt. A good rule to remember is that the smooth part of the belt should be against the smooth pulleys and the ribbed side of the belt should be wrapped around the ribbed pulleys. Lower the new belt down into the front of the engine bay.

It the noise stops, it tells you the belt needs tightening. There is a belt tensioner adjustment that is usually located half-way down the front of the engine. Normally there should be about 3/4-inch of play in the belt, and the tensioner can be adjusted to return the belt to normal tension. A very old belt may be so worn that it's impossible

For the serpentine belt: Just be sure to slightly loosen the 14mm idler-pulley nut before you adjust the 8mm threaded adjustment rod. For the smaller belt that goes around the power-steering and waterpump, be sure to loosen the 12mm nut on the side so the power-steering pump can move before you adjust the 12mm nut on the threaded adjustment rod.
Here are a few tips that may prove helpful in minimizing belt slippage, maximizing pulley bearing and belt life, and diagnosing problems with serpentine belt drives: 1. Proper Serpentine Belt Tension is Critical. Serpentine belt systems are designed to operate at a very specific tension, unlike old V-belt systems that run at maximum tension to The serpentine belt can also be called a ribbed belt, Vee-belt, or a multi belt. The are kept tight by a tensioner. It can be be tensioned automatically, or have the tension manually set. They may also use pulleys that simply route the belt properly. Strands of a broken serpentine belt stuck in the timing belt. 07 - Cooling / Accessory Drive / BELT, Serpentine / Removal 2.0L/2.4L. 1.Disconnect and isolate the battery negative cable. 2.Raise and support the vehicle. 3.Remove the belly pan. 4.Remove the right front wheel. 5.Remove the five push pins from the forward end of the right wheel liner.
The formula for calculating the belt length depends on the configuration of pulleys and the path the belt takes around them. The general formula is: Belt Length = (π/2) * (D1 + D2) + 2 * L + [ (D2 - D1)² / (4 * L)] where D1 and D2 are the diameters of the two pulleys, and L is the distance between their centers.

depends on the belt. Like mentioned you can get a cog belt or actual serpentine belt. The load I would imagine would depend on the thickness of the belt. If you only got a 3 rib honda belt I don't think it would hold much but if you got the 6 rib powerstroke diesel belt I would imagine it would hold quite a bit.
The advantage of a serpentine belt is that it has more surface area than a v-belt. The other part of the equation is the tension of the belt. Tension can increase the coefficient of friction, but too much can cause power loss and even increased wear to the belt. An engineer could design a belt system that would never slip or wear out.
Snap a long-handled ratchet or a serpentine belt tool into the square 1/2 in.-drive or 3/8 in.-drive opening. Or use a socket on the hex-shaped protruding nut. Slowly rotate the tensioner arm as far as it will turn. Then release the tension. Feel for binding and creaking in both directions.
That video is useless, guy just offers up a theory when the real solution is obvious (the belt needs to be tighten). I wouldn't be overly concerned with the belt being to tight. I've changed the serpentine belt on a Toyota 1.8L 1ZZ engine which is the big sister 1.5L 1NZ in the Yaris.
