This doesn't sound like a problem with your idler pulley to me, more like an axle or wheel bearing? But to check your pully just pull it back with the correct tool, some use a square 3/8 or 1/2 regular socket drive and a breakover works great. some you can just get the correct size boxend wrench on it and pull it back, after you have the tension off the belt remove the belt, spin idler pully and see if it is bad, try and wiggle the arm back and forth with a pry bar. it should have very little play in it. I hope this helps you Isolate your problem and Merry Christmas!

    hey check your lug nuts, also jack up your car and try and wiggle the wheels. a bad brake caliper or rotor could also cause these symtoms.

Vibration coming from front axle when coming to a stop it gets worse, brakes are good , maybe cv joint?


if you feel the pulsation in brake pedal when stopping. its a warped brake rotor thats causing it. for bad cv joint symtoms--- Unusual noises when making turns. As you are driving on the road and you make a turn at the corner, if you start hearing unusual sounds coming from under the car then this is one of the symptoms of a bad CV joint. These noises will sound like something is clicking beneath the car every time you turn the steering wheel. Evidence of a damaged boot. Steering wheel feels heavier. The steering wheel will start to feel tighter and heavier and you can hardly make simple turns to the left or right. In severe cases you might even feel heavy vibrations like you are driving down a rocky road.

The tension belt keeps coming off of my 1999 Town and Country. First the power steering fluid starts to leak, then it overheats. Now the battery is dead. I have already repaired the tension belt before...


Hi,
I assume you mean you have replaced the serpentine drive belt before? When your belt comes off, it is not operating your water pump and alternator or power steering pump, giving you the overheat and dead battery. Shouldnt make power steering fluid leak though. Does the power steering fluid leak all the time, or just when the belt comes off? If it leaks all the time from the pump area, you could have a bad seal and bearing in the pump causing the pulley to wobble and that makes the belt walk off. First, locate the belt routing diagram on the engine cowl (front of vehicle under the hood) or make a drawing of how the belt is routed for re-assembly use. Loosen belt tension at tensioner and take belt loose from a pulley that is easily accessed. Use your hands to wiggle all your pulleys and feel for excessive play in any of them or the components themselves. (water pump, power steering pump,A/C compressor and alternator.) If component play, you could have loose bolts causing wobble. If pulley play, could be bad bearing in component which would need replaced. Pay special attention to excess movement in the tensioner pulley itself. Also visually check for sideways alignment of pulleys. If pulleys are not aligned correctly, it will make the belt walk off also. That is usually a bracket misaligned or bolt holes in bracket worn out. If all checks good, I would suspect a worn out belt or belt tensioner that is not holding enough / proper tesion on belt allowing it to walk off. It will take you about an hour to check these things, repair costs depend on what you discover as a potential problem,as components can be costly.
Let us know what you find......Thanks, Mike

Gearbox chatter on tick over do they suffer from dualmass problems also is there a quick way to change the cambelt


Dual Mass Flywheel, and will also need new clutch Remove the engine coverUsing a [16 mm], rotate the tensioner arm clockwise (about 14° )and remove the belt from the pulley.
Remove the power steering pump pulley, idler pulley, tensioner pulley and crankshaft pulley.
Remove the upper and lower timing belt covers.

Remove the auto tensioner.
NOTE
Rotate the crankshaft clockwise and align the timing mark to set the No.1 cylinder's piston to TDC (compression stroke).
At this time, the timing marks of the camshaft sprocket and cylinder head cover should coincide with each other.




Unbolt the tensioner to remove the timing belt.
NOTE
If you plan to use the timing belt again, mark the rotation direction on the belt so you reinstall it correctly.

SERVICE MANUAL
Applies to: Santa Fe 2004
GROUP
Engine Mechanical System Timing System



INSTALLATION
Install the idler pulley to water pump boss.
NOTE
Insert and install the idler pulley to the roll pin that is pressed in the water pump boss.


Install the tensioner arm and plain washer to the cylinder block.
Install the tensioner pulley to the tensioner arm.
Install the camshaft sprockets and align the timing marks.

NOTE
When installing the camshaft sprockets, fasten them tightly while holding the hexagonal part of the camshaft.
Before installing the timing belt, if the timing marks of the cam sprocket and the cylinder head cover do not coincide, do not rotate the cam sprocket more than 3 teeth in either direction.
Rotating the sprocket more than 3 teeth may allow the valve and piston to touch each other.
If the cam sprocket is rotated more than 3 teeth unavoidably, rotate the crankshaft counter - clock wise a bit before rotating the cam sprocket.
Install the auto tensioner to the front case.
NOTE
At this time auto tensioner's set pin should be compressed and secured with set pin.




Align the timing marks of each sprocket and install the timing belt in the following order. Crankshaft sprocket--> Idler pulley--> camshaft sprocket (LH side)--> Water pump pulley--> camshaft sprocket (RH side)--> Tensioner pulley.
NOTE
In this step, No. 1 cylinder is in the TDC (Compression stroke).
Be very careful if you use your fingers.



Pull out the set pin of the auto tensioner.



Install the upper and lower timing belt covers.
Install the power steering pump pulley, idler pulley, tensioner pulley and crankshaft pulley.
Using the wrench [16mm], rotate the tensioner arm clockwise (about 14°) and install the belt to the pulley.
Install the engine cover.
How to adjust the tension of the timing belt
Rotate the crankshaft 2 turns clockwise and measure the projected length of the auto tensioner at TDC (# 1 Compression stroke) after 5 minutes.
The projected length should be 6-8 mm.
Verify that the timing marks of each sprocket are in their specified position.
NOTE
If the timing marks are not in their specified position, repeat from 6 above.

Ho is the power steering belt on 2002 chrysler


Click on the following direct Link. It has the Belt Diagrams you will need, complete with Removal Diagrams and Directions. It also has numerous other helpful diagrams for use.

Standard Rules to Removal the Serpentine Belt with a Tensioner:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

Standard Rules for Installing the Serpentine Belt with Tensioners:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.Com!

I HAVE HAD MY TIMING COVER GASKET REPLACED ON MY 1999 PLYMOUTH GRAND VOYAGER - 3.3 ENGINE - NOW I AM GETTING A BIG VIBRATION WHEN IDLING IN GEAR AND SOMETIMES WHEN I TURN STEERING IT CHATTERS - WOULD...


If your mechanic is a good mechanic you should be able to take it back into that mechanic and have them recheck their work at no additional cost. There are many bolts holding on the: Power Steering Pump, Alternator, Water Pump, Belt Tensioner, Crankshaft Pulley and Idle Pulley. Many of these have to be removed inorder to replace the Timing Chain Cover Gasket. It they were not tightened down correctly, this could be the vibration you are describing. Also the Front (right side) Motor Mount had to be loosened to gain access. If this was not tightened down correctly, it could cause vibration.
The Power Steering Pump itself not only has mounting bolts, but also the retaining bolts on the pulley. Again if these were not tightened down correctly, it could cause the pulley to vibrate.
Talk to the mechanic (again if you have to) and work it out with them. Most good mechanic will help you.
But to answer your question directly: Yes there is a very good possibility that this has something to do with the Timing Gasket Cover Gasket work.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at

Squeaky Unibelt


Sounds like the serpentine belt tensioner has gone bad, It's not common for any bolts to go loose but it's common for the tension arm assembly to break apart and vibrate from side to side.
The tensoner pulley does vibrate as the belt moves around it but not side to side. To check the tension arm, with the engine NOT RUNNING. Push on the belt and look at the tension arm, if it moves up and down with the belt then it's ok. If there is lateral movements (side to side) then it's bad and needs to be changed.
If you still not sure, go to Auto Zone or any auto parts store and have them help you determine if it's bad and they may have the part in stock since it's a common part that goes bad and Auto Zone has the step by step to replace it if you'll like to change it your self.
Good luck and hope this helps., P.S if it is the tension arm pulley has gone bad, do not drive too far and long. If it breaks you'll lose all the power accessory.

Steering wheel vibrates thumping noise


At what speed do you feel the shake and does it only happen when you apply the brakes?

Loosen tension on serpent belt


Hi rdt,
The tensioner is on a spring arm, no need to take it off.
  • Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
  • Get the belt around all the pulleys except the A/C compressor or Alternator.
  • The tensioner pulley is near the Alternator toward the center of the engine. It's on a spring loaded arm. Get your socket on the center nut of this pulley.
  • Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
  • Slowly release the tension.
  • You're done
