Question about 1997 Dodge Dakota

3 Answers

The instructions I have for insalling the tensioner say "The tensioners are equipped with a square hole on the tensioner to rotate the tensioner arm for installation. A 1/2" socket driver wrench is recommended for this procedure." Not sure what they mean. Do I need to do this? I also can't find any torque specs for the mounting nut.

The moving ARM of the tensioner has a 1/2" square drive keyway, to install a 1/2 sq. drive rachet, in order to lever the tensioner, when the the belt is to be installed. Then to release the tension onto the belt, when the installation is complete.

The mounting nut itself should be about 40-45 ft./lbs. torque-the 1/2" square hole is on the arm where the pulley is, you install the tensioner first, thread the belt on the pulleys and then rotate the tensioner toward the center of the engine so you can slip the belt over the tensioner pulley-you do this using the 1/2" drive rachet head inserted into that square hole, it provides you with leverage to turn the tensioner far enough to install the belt.

Yes, you use a long 1/2" ratchet or breaker bar
in the 1/2" square hole to release the belt tension

Don't need torque specs

I doubt you even own a torque wrench

How do you loosen the tensinor to replace surpintine belt

Use a tensioner pulley kit (or a 1/2" breaker bar if equipped with a 1/2" square hole) to release tension on the belt by rotating the tensioner until tension is released on the belt. properly.

Some tensioners don't have a square hole to put a breaker bar, but must be turned at the pulley's stationary hex bolt.

Good luck on replacing the serpentine belt.

Hi, use a 3/8 inch flex handle or ratchet inserted into the square hole on the extended part of the tensioner as shown in the picture below and rotate counterclockwise to relive tension on the belt. Let me know if you have more questions and thanks for using FixYa.

  1. Insert a 1/2 inch flex handle in the square hole in the tensioner. The tensioner has a square hole cast into the rear of the tensioner body directly behind the pulley. Rotate the tensioner clockwise and remove the belt from the pulleys.

NOTE As an alternate method, a 16mm socket can be placed on the tensioner pulley bolt and rotated clockwise to remove the belt.

To install:
  1. Following the schematic on the decal under the hood, loop the drive belt over all the pulleys except the alternator pulley.
  2. With the belt installed properly on all except the alternator pulley, rotate the tensioner as described above and install the belt on the alternator pulley. Ensure that all the V-grooves make proper contact with the pulleys.

4.6L Engine
WARNING Do not allow the drive belt tensioner to snap back as damage to the drive belt tensioner or personal injury could result.

  1. Rotate the drive belt tensioner clockwise with a breaker bar installed in the 3/8 inch square hole in the drive belt tensioner.
  2. Lift the drive belt over the idler pulley flange and remove the drive belt.
To install:

How do you remove tension from power steering belt

Hi Jeremy, Over here in Australia the Montero is badged as a 'Pajero'. I have a 2003 model but I presume the serpentine belt or accesory drive belt would be similar in both models and drives the power steering.

The belt most likely has an automatic tensioner as mine does. The tensioner looks like two small pulleys about 21/2" in diameter. The top one should have a square hole cutout for inserting a square peg handle to rotate the tensioner clockwise to release tension on belt.

If you can't find it - start your engine and with the hood popped rev the engine a few times. You should see the belt flexing and the tensioner will be the unit which flexes up and down to maintain the tension - all other pulleys should be rotating in a fixed position only.

Just to the right of the afore mentioned square hole is a small 1/4" hole which lines up with another hole when you rotate the tensioner clockwise to release the tension. Line up the holes and put an allen key or small screw driver through the holes to keep the tension released.

Naturally, I didn't have a square pegged hadle to lever the tensioner so I used a small gemmy or crow bar (whatever you call them in the USA) and levered between the crank pulley and the tensioner to rotate the tensioner clockwise. Be gentle and remember to remove the allen key/screw driver when you have finished.

Good Luck.

  3. Remove belt from water pump pulley first.
  4. Remove belt from vehicle.


To install:

WARNING When installing the accessory drive belt, the belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. The correct belt with correct length must be used. Position drive belt over all pulleys except water pump pulley.

2002 crysler voyager 3.3 can't get the Alternator Belt Tensioner to move.the instructions reed as follows Release tension by rotating the tensioner clockwise. the tensioner diagram looks completly...

Either in the center of the tension pulley or arm the tension pulley is bolted to there is a square hole that a 1/2" drive socket wrench will fit in. Find the hole, put the socket wrench or breaker bar in the holy and rotate it clockwise and that should release the tension.
