SOURCE: how to replace serpentine belt for 96 bonnville

This is a fairly straightforward mechanical procedure. If you will allow me to provide a little perspective first, just so we start on the same page.

Since you ask only for the procedure for replacement, I do not want to jump over the diagnostic element of this process. If you are holding a broken belt in your hand you can skip directly past this paragraph. The serpentine belt, referred to as the engine drivebelt does what fan belts did in the "old days". This belt is by the crankshaft and in turn spins the alternator, the water pump and the pump for the power steering and the air conditioner compressor. This belt is a wear item and should be examined once per year. The belt is smooth on one side and has ribs running long ways on the other side. Using a flashlight check for shiny areas, cracks of any kind or fluid on the belt. Any of these, change the belt.

Now we need to get our navigational landmarks in sync. The engine in most front-wheel drive vehicles is mounted transversely (sideways). So front and back of the engine become left (front of engine) and right (rear of engine). The drivebelt is on the front of the engine, so to your left as you raise the hood and peer inside.

There should be a drivebelt routing decal on the upper radiator panel (between the engine and the front of the car). I recommend at this point that you also take a few pictures of the drivebelt with your cell phone or digital camera. Detail its path around all accessory components. I know that this is belt and suspenders but it will help greatly with replacement. Now look for the belt tensioner under the power steering pump. The power steering pump is at 12:00 o'clock on the front of the engine. Read the sticker on the square power steering reservoir at the top front of the engine to ensure you are in the right place. The tensioner is the round pulley that looks like it it isn't attached to anything and therefore has no purpose. Put the appropriate wrench on the nut on the front of the tensioner and turn counterclockwise (push toward the back of the car). A long handled ratchet works best here since you will need to get some leverage to turn the tensioner. This will loosen tension on the belt. While holding the belt tensioner remove the belt from all of the pulleys and pull it out. When you release the belt tensioner, it will swing down out of the way. Now again rotate the belt tensioner and route the new belt onto the engine. This should do it. If you are going to be doing this intermediate level of repair and maintenance I recommend you get a hard-copy repair manual for your vehicle or subscribe to one of the many excellent repair on-line service. Good luck!

SOURCE: how to replace a serpentine belt on a 2004

  1. Lift the car so you can work from underneath when needed.
  2. Disconnect the battery . Just to be safe.
  3. Take the serpentine belt off.
  4. Remove the alternator.
  5. Remove the A/C compressor. (You can do it without removing, but it's a royal PITA... LOL) Don't unhook the lines, just unbolt and move out of the way.
  6. Remove the worn tensioner from t he block. (You need to unbolt the pulley first to get to all the tensioner bolts)

SOURCE: serpentine belt replacement

You will only need to locate the fan belt diagram to replace it on correctly and a 1/2 breaker bar or ratchet to back off the tension er while replacing belts check the tension-er bearing if it feels ruff when you turn it replace it. Check water pump also to see if it turns smooth same with the alt.

What is the average life of a serpentine belt?


It varies from vehicle to vehicle but you could ask the dealer---my view has always been to keep an eye on the belt for cracks or fraying anywhere---they are not that hard to replace and while costs will vary (on mine found a OEM one new for 26 dollars and same belt at local parts place was 52---same brand and part number.

It is better to replace it and have the tension unit that tightens most of these inspected than have it go when you are driving down the road.

In my case I keep the old belt rolled up and stowed in the vehicle in case the new one fails.

Check charging system light comes on intermittant, 2006 taurus, any speed and any load, battery good, alternator replaced problem persists before and after


Check to ensure that the belt is tight. Sometimes the tensioner for the serpentine belt sticks and doesn't properly tension the belt. Usually there's a square hole in the tensioner that one can place a breaker bar into to gain leverage to move the tensioner.

How to change serpentine belt on 2006 buick lacrosse


Start by drawing a diagram of the belt routing. Serpentine belts normaly have 1 spring loaded tensioner (1 pully will have a nut or 3/8 or 1/2 inch drive hole) That will be the tensioner. get spanner or ratchet to fit & lever the tensioner away from the belt. Remove belt. fit new belt to most pullys except the easiest to get to, lever the tenioner back & fit the belt to the last pully, Check the belt is on all pullys properly & your done

How do I replace the Airconditioning/power steering belt on a Grand marquis, Mercury(1992)? please show me in a diagram or print somehow


Move the Grand Marquis's serpentine belt tensioner off the serpentine belt with the serpentine belt tool. Pull the belt of the remaining pulleys by hand. Take the belt out of the engine well. Wrap the new belt around the bottom portion of the crankshaft pulley. Follow the belt routing diagram to route the belt over each remaining pulley until only the tensioner remains. Move the Grand Marquis's serpentine belt tensioner aside once more and slip the belt onto the tensioner pulley.Hold the belt in place with one hand while you move the tensioner slowly back into position with the other. Here you can fine the quality AC parts http://www.1airconditioning.com/ac_compresor.htm

What is the problem if the serpentine belt keeps coming off.Also when cr is running it is a sqealing sound


The squealing sound you are hearing is the serpentine belt slipping. There are a couple of things this might be. Your serpentine belt may be stretched and no longer fits properly. If the belt is old and starting to dry out you will notice cracks and possibly pieces out of the channels on it. You should look to replace this if you haven't already. The belt itself may not be threaded through all the wheels properly and that is why it does not fit properly. Here is a link to see the serpentine belt diagram for your car. Simply choose the make, model, year and engine for your car to see how it should be properly installed.
http://www.2carpros.com/diagrams It may also be that the belt tension-er is no longer working properly. If you are not sure which wheel is the belt tensioner check the diagram from the link I provided above. Once you know which one the tensioner is, use a wrench or socket wrench to make sure that it still has motion and that there is no part where there is motion but no pressure. If this is the case the tensioner needs to be replaced. It is not difficult to replace, there are usually 2 or 3 bolts that hold it on, that need to be removed then bolt on the new tensioner. Hope this helps. Thanks for using FixYa.

How do i take of a pulley and tensioner of a 94 Dodge Caravan 3.0 L V6


You'll need a Serpentine Belt Tool and a socket set.

Rotate the Caravan's serpentine belt tensioner assembly clockwise to relieve the tension on the belt. Slip the belt off the tensioner with your free hand before rotating the tensioner back to its home position. Remove the tool.
Extract the two mounting bolts that hold the serpentine belt tensioner assembly to the Caravan's front engine cover using your socket set. Depending on your physical size and dexterity, you may find this easier to accomplish through the top of the engine well or through the passenger-side wheel well.
Pull the old serpentine belt tensioner assembly out of the Caravan's engine bay by hand. Place the new serpentine belt tensioner assembly on the Caravan's front engine cover and bolt it in using your socket set.
Rotate the new serpentine belt tensioner assembly clockwise with the serpentine belt tool and then place the belt on the pulley by hand. Rotate the new serpentine belt tensioner assembly back into place. Remove the tool and close the hood.

Change serpentine belt on 06 sienna


  1. 1 Check to ensure the Sienna's engine is cold, then make sure the Sienna is in park, the ignition is in the off position and the key is removed from the ignition to prevent any possibility of the engine engaging during the serpentine belt replacement.
  2. 2 Open the hood and locate the serpentine belt routing diagram sticker on the side of the engine casing. Study it for a moment before removing the existing belt. It is essential the new belt be installed exactly as the diagram indicates.
  3. 3 Find the tensioner pulley, the main pulley that controls the serpentine belt, and fit a 1/2-inch socket wrench over the self-tensioner on the outside of the pulley.
  4. 4 Pull the wrench to the left to move the pulley forward, which loosens the belt, then remove the belt.
  5. 5 Compare the old serpentine belt with the new, replacement belt for length, width and number of grooves on the belt's underside. Be certain the replacement belt is the right part.
  6. 6 Fit the new belt on to each pulley according to the serpentine belt routing diagram on the manufacturer's sticker, or according to the drawing made prior to removing the old belt. Fit the new belt on to the tensioner pulley last, again applying pressure on the pulley's self-tensioner with the half-inch socket wrench to loosen the pulley.
  7. 7 Release the pressure on the self tensioner and allow the tensioner pulley to ease back into place, thereby tightening the new serpentine belt with the appropriate tension.
  8. 8 Remove the wrench and close the hood.
Thank you and good luck,
Lee

How do I replace a Serpentine Belt on a 1994 E420?


The tensioner will keep the belt tight without having to adjust. It's on a spring loaded type arm. The tensioner is on a arm, if you look at the center of the roller you will see either a 1/2" hole or it could be a allen type wrench hole. You will need to fit a ratchet into the hole or an allen wrench with a pull handle for better leverage. Once you have this inserted into the hole, you will either push or pull slightly to compress the spring which will give you room to fit the belt over the last pulley. Once this is done the tensioner will automatically tighten the belt once you release the pull handle. You are set and ready to go

I need to replace the idler pulley/tensioner and the belt


When this idler wears out it makes a growling noise that changes with engine RPM. A Bad Idler Pulley May Wobble & Wear Out Your Serpentine Belt Prematurely. Get Rid Of That Horrible Noise & Change.

Remove the serpentine belt by using a breakover bar, ratcher or serpentine belt removal tool with the correct size socket for the pulley mounting bolt. Rotate tensioner arm to release tension. Remove the bel. Using the proper size socket, remove the tensiones mounting bolt and remove tensioner.

Before installing the new tensioner, make sure the mounting surface for the tensiones is clean and free rust or other obstructions. Find the locator pin hole and rotate the replacement tensiones until the locator pin and the hole line uo. Insert the pin into the hole. Reinstall the mounting bilt and torque down to tight fit.

Rotate the tensioner arm to install the serpentine belt. Make sure the belt is correctly fitted to all pulley in the drive system. Start the engine to check for any problems. Extreme care should be taken when reinstalling the serpentine belt because some of the pulleys are located in remote positions ans it is very hard to see that belt is seated properly in all of the grooves. If the belt isn't seated properly, the belt can "ride out" of the grooves and the belt can be damaged.

Also must review the ZJ Repair Manual Secc-7-Cooling-System for graphics references.

Hope helped with this. Remember rated this help. Good luck.
