I have loosed all the bolts that I can see, that should allow the power steering pump to slide inward to be able to install the new belt. But it wont budge, Can you tell me what I might be doing wrong? I would appreciate any help / advise with this mater. Thank you
I had to completely remove the adjuster bolt, including the lock bolt, so that I could move the P/S pump enough to get the new belt on. It was still a tight fit. I find that removing the headlamp assembly makes access much easier.

I've got an 85 2.5 celebrity and am assuming that your 86 is similar. Most people might think this is a incorrect question, but I've spend hours trying to locate all the bolts to loosen. The alternator belt is straightforward. Loosen the alternator bolt in located in the slider portion and the pivot bolt (15mm on mine). The compressor belt is straightforward. Loosen the two compressor adjustment bolts in the slider slot and the loosen the pivot bolt. This belt will be hard to remove even with the compressor fully pushed down. Take some vitamins. The worse belt by far is the power steering belt. Loosen the pivot bolt on the bottom of the power steering "canister". There are two adjustment bolts to loosen from my memory. The one that is easy to find is on the engine side of the power steering canister. The other is hard to see but is located on the pulley side between two of the pulleys. It's also hard to get a wrench on. But, you've got to find and loosen this bolt. I cringe when this belt breaks. Good Luck!!
Check this procedure for Pontiac 3.8L Engine - Water Pump
Before servicing the vehicle, refer to the Precautions Section.
Drain the engine coolant.
Remove or disconnect the following:
Negative battery cable.
Water pump pulley
Power steering pump and move it aside
Fig. Exploded view of the water pump assembly mounting-3.8L engine
Install or connect the following:
Water pump using a new gasket and torque the long bolts to 25 ft. lbs. (34 Nm) and the short bolts to 16 ft. lbs. (22 Nm)
Water pump pulley and torque the bolts to 115 inch lbs. (13 Nm)
Power steering pump and torque the bolts to 25 ft. lbs. (34 Nm)
Negative battery cable
Fill the cooling system.
Start the vehicle and check for leaks, repair if necessary.
This is how the steps on how to changepower steering pump on GMC K1500. First you have to disconnect the battery byturning the positive terminal bolt counterclockwise and removing the lead. Thendisconnect the lower power steering line by turning the line nutcounterclockwise. Allow the pump to drain in the drain pan. Once the pump isdrained, disconnect the upper line by turning the line nut counterclockwise.
2. But on older models, turn the adjustmentmount bolt counterclockwise until the tension on the primary drive belt isrelieved. Remove the belt from the power steering pump pulley. Remove theremaining mount bolts by turning them counterclockwise. Maneuver the pump fromthe engine.
3. On newer models, press the tensionpulley arm to slacken the belt enough to slide it from underneath the idlepulley wheel. Release the tension pulley arm. There should then be enough slackto take the belt from the power steering pump pulley. It may be necessary toremove the A/C compressor on some models. Remove it by having it evacuated ofall freon, removing the wiring harness adapter plug, removing the line nuts,and then turning the mount bolts counterclockwise; taking the compressor outgives improved access to the power steering pump. Remove the pump by using thespecialized tool (available for rent at an auto parts store) to turn the centermount bolt counterclockwise. Maneuver the pump from the engine compartment.
4. Replace the pump and attach the mountbolts by turning them clockwise. Reattach the line nuts by turning themclockwise. Replace the drive belt by the tension pulley method (serpentinebelts), or using the adjustment bolt to pull the pump to the desired belttension. Replace the fluid to the proper cold level.
5. Reconnect the battery by attaching thelead and turning the positive terminal bolt clockwise.
Disconnect battery ground cable, then remove exhaust manifold heat shield.
Disengage power steering pump reservoir hose from pump bracket and engine lifting bracket, then disconnect return hose and reservoir pump hose from pump.
Allow fluid to drain into a suitable container, then raise and support vehicle.
Remove lower belt guard, then rotate drive belt tensioner clockwise as viewed from direction shown, and remove accessory drive belt.
Lower vehicle, then remove traction assist module bolts and position module aside.
Rotate power steering pump pulley to gain access to each pump front mounting bolt, then remove three front bolts and one rear bolt and lift pump from vehicle.
If it is necessary to separate pulley from power steering pump, proceed as follows:
install power steering pump pulley remover T69L-10300-B, or equivalent, on pulley hub.
Clamp hex head of tool in a suitable vise, then hold power steering pump in place while turning tool nut counterclockwise. Do not apply inward or outward force on power steering pump shaft, internal pump damage may result.
Slide pulley from power steering pump shaft.
Reverse procedure to install, noting following:
If pulley and power steering pump were separated, install pulley on pump shaft using power steering pump pulley replacer T91P-3A733-A, or equivalent. Ensure threads on end of tool are fully engaged in power steering pump shaft; after pulley installation, ensure end of shaft is within 0.010 inch of being flush with pulley surface.
When placing pump in vehicle, install rear mounting bolt first, but do not tighten until three front bolts are in position.
Rotate drive belt tensioner clockwise as viewed from direction shown to install accessory drive belt.
Refill power steering fluid reservoir and bleed system.
To replace the power steering pump, proceed as follows:
Disconnect the power steering return hose from the remote reservoir or pump. Allow the fluid to drain from this hose into a drain pan. Discard the used fluid.
Loosen the bracket or belt tension adjusting bolt, and the pump mounting bolt.
Loosen the belt tension until the belt can be removed. On some cars, it is necessary to lift the vehicle on a hoist and gain access to the power steering pump from underneath the vehicle.
Remove the hoses from the pump, and cap the pump fittings and hoses.
Remove the belt tension adjusting bolt and the mounting bolt, and remove the pump.
Check the pump mounting bolts and bolt holes for wear. Worn bolts must be replaced. If the bolt mounting holes in the pump are worn, pump replacement is necessary.
Reverse steps 1 through 5 to install the power steering pump. Tighten the belt as described previously, and tighten the pump mounting and bracket bolts to the manufacturer's specifications. If o-rings are used on the pressure hose, replace the o-rings. Be sure the hoses are not contacting the exhaust manifold, catalytic converter, or exhaust pipe during or after pump replacement.
Fill the pump reservoir with the manufacturer's recommended power steering fluid, and bleed air from the power steering system as described earlier.
Loosen 2 pivot bolts on back of pump, 13mm. then loose one bolt on bottom/front. Turn adjustment bolt on right side/bottom of pump to loosen belt. Once belt if off, remove all of the bolts connection pump to engine bracket. Remove hoses going to pump. Install new one, filled up with fluid. Now you have to bleed air out of sys. Move steering wheel left/right to the stops. Do this about 10 times either direction.
