I don't know if your serpentine belt layout is the same as mine. I have a 2005 2.4TD. I worked out that the tensioner is spring loaded and needed to be turned using a very long spanner (can't remember the size as I used an adjustable spanner with a piece of pipe to get the length - 19mm sounds right). Get the belt wrapped round the other pulleys and then turn the tensioner pulley nut a quarter turn or so then the belt should slip onto the last idler pulley. Make sure all pulleys have any rubber residues and oil/muck cleaned off. Very tight for space so you'll probable end up using yours fingernails and a rag with some petrol or WD40 on it. Re-fitting the engine pan was the worst bit. **** design for the fittings. Replaced these with self-tapper screws to make sure it stays on as the original clips don't like being taken off and put on too many times. Thanks Chrysler. By the way I'm never buying a Chrysler again. Had to replace both wishbones after 3 years - a common problem I'm told - and also this is the 4th serpentine belt in 8 months and its going to be an expensive process of deduction to find out what the problem is. Recirculate button for the aircon has also decided to stop working. Great news given that its minus 3 outside and the car takes 20 minutes to warm up the interior as its sucking in cold external air. I've also got a 1996 Toyota Picnic 2.0 auto with double the mileage that I've owned for 5 years. All I've ever had to do with that is replace a rear lightbulb and I know the previous owner who never had a fault with it. 14 years old and only needed one bulb changed in all that time! Still on the second set of tyres too. Best car I've ever had. The Cruiser is turning out to be as expensive to maintain as my old Citroen XM, and they are famous for maintenance problems. Lovely car though. Hope this helps and puts people off buying Chrysler ****...

    I sussed the problem with the Cruiser eating serpentine belts after much time spent investigating the pulleys and tensioner etc... Out of frustration I simply fitted a belt a size bigger and that has cured it. I was expecting slipping and squealing but it was good. Problem now sorted and it didn't need me swearing and wrestling with it to force it onto the pulleys like before. I haven't had any issues since I fitted the longer belt and now recommend this fix.

    I have absolutely no idea why the standard size belt is too small but there you go. I can now confidently take it on long journeys without a toolbox, axle stands, and a couple of spare belts in the boot. Yeh! Now I've sorted it I'm selling it!

    Spanner for turning the tensioner is 14mm by the way and not 19mm as I suggested before.

    Hope this helps :)

I'm replacing the serpentine belt on a 2001 cherokee sport 4.0 and the belt tension adjustor does not seem to be loosening the pulley. got the old belt off, but cannot get the new belt back on.
page 1, line 1 (serp)
Tension is maintained using an automatic tensioner pulley assembly. The drive belt is tensioned by adjusting the position of the idler pulley, accomplished by moving the adjuster bolt on the idler mechanism.

here, pasted in whole.

Serpentine Belt Because serpentine belts use a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than it used to be on engines where accessories were pivoted and bolted in place for tension adjustment. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. The two most important points are to pay CLOSE attention to the proper belt routing (since serpentine belts tend to be "snaked'' all different ways through the pulleys) and to make sure the V-ribs are properly seated in all the pulleys.
Although belt routing diagrams have been included in this section, the first places you should check for proper belt routing are the labels in your engine compartment. These should include a belt routing diagram which may reflect changes made during a production run.
  1. Disconnect the negative battery cable for safety. This will help assure that no one mistakenly cranks the engine over with your hands between the pulleys, and that the cooling fan cannot activate while servicing the belt(s). NOTE Take a good look at the installed belt and make a note of the routing. Before removing the belt, make sure the routing matches that of the belt routing diagram. If for some reason a diagram does not match (you may not have the original engine or it may have been modified), carefully note the changes on a piece of paper.
  2. For tensioners equipped with a 1/2 in. (13mm) square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself.
  3. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioner's internal parts.
  4. Now finish removing the belt from the other pulleys and remove it from the engine.
To install:
  1. While referring to the proper routing diagram (which you identified earlier), begin to route the belt over the pulleys, leaving whichever pulley you first released it from for last.
  2. Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the belt.
  3. Once the belt is installed, take another look at all the pulleys to double check your installation.
  4. Connect the negative battery cable, then start and run the engine to check belt operation.
  5. Once the engine has reached normal operating temperature, turn the ignition OFF and check that the belt tensioner arrow is within the proper adjustment range.

Should timing belt tensioner be replaced on 2001 pt cruiser?

It is highly recommended that the timing belt tensioner be replaced any time the belt is replaced, if the bearing in the tensioner failed it will take out the new belt in an instant.

Serpentine belt is slipping

I would suspect that your belt tensioner is bad. It has a large spring inside that keeps the belt tight. The spring becomes weak, causing the belt to be loose.

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,

Looking for a diagrahn of a 2001 pt cruiser

The tensioner will be down lower and it will have a large metal roller wheel attached to it that is pushing against the timing belt to take the slack out of the timing belt, and you should be able to see it if the timing cover is removed, here is a picture of what you are looking for, and let me know if you still can not find it, or you require further assistance .5658e28.jpg
