No power steering no belt on pump no belt on ac why would they be removed

Removing the AC pump and power steering pump from a 1999 Isuzu Trooper 3.5L can be a complex and time-consuming process. It is recommended that this procedure be performed by a qualified mechanic. However, if you would like to attempt it yourself, the following are general steps to follow:

1. Disconnect the negative battery cable.
2. Remove the serpentine belt by using a breaker bar or ratchet on the tensioner pulley to relieve the tension on the belt. Then, slide the belt off the pulleys.
3. Remove the bolts that secure the AC pump and power steering pump to the engine block. The AC pump and power steering pump share some bolts, so be sure to keep track of which bolts belong to which pump.
4. Disconnect the electrical connectors and hoses from the AC pump and power steering pump. The electrical connectors may require you to depress a tab or pull up on a locking tab before disconnecting.
5. Remove the bolts that secure the AC pump and power steering pump to their respective mounting brackets.
6. Carefully lift the AC pump and power steering pump out of the engine compartment.
7. If you plan to reinstall the AC pump and power steering pump, transfer any necessary components or brackets from the old pumps to the new pumps.
8. Install the new pumps in reverse order, using the bolts and connectors you removed from the old pumps.
9. Reinstall the serpentine belt, making sure it is properly routed around all the pulleys.
10. Reconnect the negative battery cable.
11. Start the engine and check for proper operation of the AC and power steering systems.

You can't miss the power steering pump because it has to be belt driven. The only other belt driven devices are AC and alternator. And while the hoses on the AC are similar, the power steering pump is much smaller.

Tighten, your need to tighten the power steering belt a lil bit more, not to much to stretch it but just enough to overcome the resistance of the pump

Belt goes over power steering pump,under idler on left,over AC compressor,over alternator,over fan (with back of belt ) over crank pulley then over water pump (back of belt) then back to p/s pump. Routing is counterclockwise.

You need to remove the AC/Alternator belt first. There is a pivot bolt on the alternator that needs to be loosened. It faces toward the driver's side under the alternator. Then on top there is a long bolt that needs to be loosened. As it loosens push the alternator down and you will get enough slack to remove the belt.

For the power steering belt, remove the front passenger-side wheel. You will see a black cover(called a fender apron)- remove it. I believe the bolts are 10mm. You can now see the power steering pump- look at the side of the pump that faces the firewall. You will see another long bolt (similar to the AC/Alternator adjustment bolt), loosen it some and push the pump to get slack in the belt.

Power Steering Pump Removal & Installation Power Steering Pump (2V) To Remove:

1. Before servicing the vehicle refer to the precautions at the beginning of this section.
2. Disconnect the battery ground cable.
3. Remove the accessory drive belt.
4. Remove the alternator.
5. Drain and remove the radiator coolant recovery reservoir.
6. Position a drain pan under the power steering pump underneath the vehicle. Disconnect the hydraulic pressure and return lines and allow to drain.
7. Remove the idler pulley from the power steering pump support.
8. Remove the belt tensioner.
9. Remove the bracket mounting bolt located under the belt tensioner mounting.
10. Remove two retaining nuts from the bracket mounting studs. Remove both mounting studs, and pull off the power steering pump support with the pump attached.
11. Clamp the pump support bracket in a suitable vise.
12. Remove the power steering pump pulley from the pump shaft using Pump Pulley Remover T69L-10300-B, or equivalent. Remove the three bolts retaining the power steering pump to the power steering pump support and remove the power steering pump.

To Install:
NOTE: The pulley must be installed within 0.010 in (0.25 mm) flush with the power steering pump shaft.

1. Install the power steering pump to the power steering pump support. Tighten the mounting bolts to 18 ft-lb. (25 Nm).
2. Install the power steering pump pulley using Steering Pump Pulley Replacer T65P-3A733-C, or equivalent; the pulley face must be flush within 0.010 inch (0.25mm) of the pump shaft.
3. Install the power steering pump/pump support and torque nuts/bolt to 24 ft. lbs. (33 Nm).
4. Install the bracket mounting bolt located under the belt tensioner mounting.
5. Install the belt tensioner.
6. Install the idler pulley to the power steering pump support.
7. Connect the hydraulic pressure and return lines.
8. Install the radiator coolant recovery reservoir.
9. Install the alternator.
10. Install the accessory drive belt.
11. Fill the power steering reservoir with power steering fluid.
12. Connect the battery ground cable.
13. Run the engine and check for leaks and proper operation. Bleed the power steering system if needed.

Park vehicle on level ground.
2. Remove battery from vehicle.
3. Remove air cleaner outlet hose, engine under cover ( right side ) and exhaust pipe # 2 .
4. Disconnect " B " terminal wire and coupler from the Alternator ( Generator ) .
5. Remove Alternator ( Generator ) belt.

6. Remove power steering pump. Do not disconnect hoses.
6. Remove Alternator ( Generator ) cover.
7. Remove Alternator ( Generator ) bracket mounting bolts.
8. Remove Alternator ( Generator ).

Power Steering pump has three bolts- 2 behind the pulley at 12 and 6 o'clock and one bolt on the back.

Once you get the power steering pump out of the way you can remove the last bolt on the alternator

Ok...I did not remove axle or disconnect hoses on power steering...I did unbolt power steering pump and moved off to side.

after that I disconnected sensor on throttle body and very carefully lifted alternator through the top where your air intake assembly would have been at, right next to A.C. refrigerant lines.It takes a minute , you HAVE TO BE CAREFUL NOT TO DAMAGE SENSOR!!

However it is a lot faster that taking off drive shaft and exhaust pipe!

If you go to AutoZone .com they have exploded diagrams of the parts you have to take off and they will show you bolt locations, the power steering pump bolt at 6 o'clock drove me crazy.

P.S. Get a ratcheting 12 mil wrench, it's a life and knuckle saver!!
