Trying to R & R the serpentine belt on a 1999 Olds Delta 88. The belt is routed arond a motor mount. Do I have to jack the motor and disconnect it from the motor mount in order to remove and replace...

yes you do. place a floor jack under engine with a block of wood on top of jack to protect the engine, put just enough pressure on jack to steady engine. remove motor mount, then jack up engine a bit to take belt off. replace the belt then lower jack and attach the mount. on the mount only the outside bolts need to come off to raise engine. do not remove from engine side unless you are changing it or its bad, be carefull when raising engine, pick it up from a sturdy place, not the oil pan. have a good day !!

How to Replace a Power Steering Belt

This is how to replace the power steering belt in 1995 ford explorer.
1. Disconnect the negative battery cable from the negative post on the battery. Loosen the retaining bolt with a socket and ratchet, then remove the cable end from the terminal. Isolate the cable end from the battery to prevent accidental starting of the engine while you are working.
2. Locate the serpentine belt tensioner on the front of the engine and attach a socket and ratchet to the mounting bolt in the center of the pulley. Rotate the tensioner clockwise to relieve the tension on the belt. Remove the belt from the pulleys while holding the tensioner away from the belt. Discard the old belt. Release the tensioner, slowly rotating it to the home position.
3. Install the new serpentine belt over all the pulleys except the tensioner pulley. Rotate the tensioner clockwise and slide the new belt onto the tensioner pulley. Slowly rotate the tensioner counterclockwise, allowing it to tighten the belt.
4. Remove the socket and ratchet from the tensioner pulley. Install the negative battery cable on to the negative terminal of the battery. Tighten the retaining bolt with a socket and ratchet.
5. Start the engine, verifying that the belt is mounted correctly and running true over the pulleys.

How to change serpentine belt?

You will need to put a jack under the front of the engine then remove the motor mount. You should be able to remove the serpentine belt then and install the new one. Good Luck

I am in the process to install a new alternator for which I need to loosen the belt. Is there a tensioner and what does it look like ?

Don't know what size of motor you have but this should help you:

Removal & Installation
  1. Loosen the accessory-to-mounting bracket bolt(s) and adjusting bolt.
  2. Rotate the accessory to relieve belt tension.
  3. Slip the drive belt from the accessory pulley and remove it from the engine.

If the engine uses more than one belt, it may be necessary to remove belts that are in front of the belt being removed

To install:


If the engine uses more than one belt, it may be necessary to remove belts that are in front of the belt being removed

  1. Place the new belt over the crankshaft or drive pulley and stretch over the driven (accessory) pulley.
  2. If removed, install the other belts in the same way.
  3. Adjust the belts to the proper tension.
  4. Tighten the adjusting and mounting bolts.

Models equipped with the V6 engine and most 1987-94 engines use a single (serpentine belt) to drive all engine accessories. The serpentine belt driven accessories are rigidly mounted with belt tension maintained by a spring loaded tensioner assembly. The belt tensioner has the ability to control belt tension over a fairly broad range of belt lengths. However, there are limits to the tensioner's ability to compensate for varying lengths of belts. Poor tension control and/or damage to the tensioner could result with the tensioner operating outside of its range.

To replace the belt push (rotate) the the belt tensioner and remove the belt. Use a 15mm socket on the 4-cyl. engines and a 3/4 in. open end wrench on the V6 engines.
