Insert a ratchet or other 3/8 drive into hole in front of tensioner, right under alternator,pull to relieve tension on belt and remove belt from alt. Remember how the belt is routed.If you are not going to replace the belt then after getting it off the alt keep tension on it ,so it stays on the other pulleys, touch inside of belt together and hold it together with a clamp (clothes pin or vice grip) or tape. Whatever you use do not apply to much pressure or you may wreck the belt.

One may need to get a breaker bar or a pulley tensioner wrench set from your local auto parts store to easily reach the tensioner pulley. Sometimes at places like Autozone and Advance Auto Parts the tool set can be purchased and returned, essentially, borrowing the tool set from them.
What tool are you using to release the tension from the belt?

  1. Disconnect the negative battery cable.
  2. Remove the accessory drive belt. After disconnecting the battery and removing the drive belt, unplug the single wire connector . . . Im trying to remove my - 89682p01.jpg
    . . . then the multi-wire connector from the back of the alternator - integral regulator units lack the single wire 89682p03.jpg
    If the push-on connectors are difficult to remove, use a small pick to disengage the connector latch 89682p02.jpg
    Unbolt the battery (B+) lead from the back of the alternator . . . Im trying to remove my - 89682p04.jpg89682p04.jpg

  3. Label and disengage all of the wiring connectors from the alternator. To disconnect push-on type terminals, disengage the lock tab and pull straight off.
  4. Remove the alternator bolts, then remove the alternator from the engine . . . then remove the altIm trying to remove my - 89682p05.jpgting bolts 89682p05.jpg

    To install:
  5. Position the alternator on the engine.
  6. Install the alternator mounting bolts. On 3.8L and 5.0L engines, tighten the upper bolt to 16-21 ft. lbs. (21-29 Nm) and the lower bolt to 30-40 ft. lbs. (40-55 Nm). On 4.6L engines, tighten both bolts to 15-22 ft. lbs. (20-30 Nm).
  7. On 4.6L engines, install the alternator mounting bracket and bolts. Tighten the bolts to 71-106 inch lbs. (8-12 Nm).
  8. Install the accessory drive belt. Ensure that the drive belt is properly installed on the pulleys before starting the engine.
  9. Attach all engine wiring harness connectors to the alternator.
  10. Connect the negative battery cable.

My 1996 ford windstar 3.8 liter engine tensioner pulley is making a vibrating noise . do I have to replace the whole arm or just the pulley or both? Also ,if I just have to replace the pulley is the bolt...

It probably comes as a unit. tensioners create tension by way of spring and springs do wear out over time. so it may be beneficial to change the whole tensioner. there is a bolt in the center of the tensioner remove it and on reinstall remeber to line up the dowel pin. good luck

Cant find drive belt tensioner bolt to loosen serpintine belt

The serpentine belt tensioner / pulley is on the front of the engine, and part of the belt 'routing'.

Its job is to put tension on the belt as it drives the other devices like the power steering pump, water pump, air conditioning compressor.

It is an aluminum casting that mounts with a single bolt to the engine. The pulley is attached to the arm.

There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket.

I cant find the tension? I get it on the pulleys,

The tension release pulley, located just below and in front of alternator, has a 1-2 slot in the center of pulley. Insert the 1-2 inch breaker bar in middle of tension pulley and pull up, tension will be released. I hope this helps. Don,t forget to rate my answer, thanks.

1999 ford windstar altenator

there is a tensioner on the belt... it's a pulley near the back by the firewall that doesn't appear to drive anything. you will note a square hole in the side of it... that fits a 3/8 in ratchet.... use a long pry bar with that socket type ... on mine you have to pull it down i believe to remove tension... try it to make sure which direction it has to move.
