QuestionQUESTION: Hi,
LAst night my Power Steering Pump decided to start grinding by the time I got to a spot to pull over there was smoke everywhere I'm assuming it is shot at this point b/c I put fluid in the resivour and it just spill out underneath the van within a few minutes. Wondering If you can give me directions on how figure out where the hoses run so I can check them first and also to remove and replace this pump. Any help at all would be great.
Thanks.
ANSWER: Hi Robin,
The hose routing should be fairly clear if none are detached. The procedure for changing it changed between '99 and '02 so I can't be sure which applies to your '00 bit take a look at the pump fluid reservoir shape as a clue as to which procedure is applicable.
This is the procedure for r&r the pump from the '99 manual which I believe applies to your vehicle if it has the square reservoir for the fluid:
REMOVAL
Remove the (-) negative battery cable from the battery and isolate cable.
Remove cap from power steering fluid reservoir.
Using a siphon pump, remove as much power steering fluid as possible from the power steering fluid reservoir.
Raise vehicle on jack stands or centered on a frame contact type hoist. See Hoisting, in the Lubrication and Maintenance section of this MDS2 for the required lifting procedure.
Disconnect the oxygen sensor wiring harness from the vehicle wiring harness. Access to connection at vehicle wiring harness is through the oxygen sensor wiring harness grommet in the floor pan of the vehicle
NOTE: The exhaust system needs to be removed from the engine to allow for an area to remove the power steering pump from the vehicle.
Remove the catalytic converter from the exhaust manifold. Then remove all the exhaust system hangers/isolators from the brackets on the exhaust system.
Move the exhaust system as far rearward and to the left side of the vehicle as possible Exhaust Position For Removing Power Steering Pump
Raise the heat sleeve on the power steering hoses to expose the hose to steel tube connection. Remove the hose from the power steering fluid return line on the front suspension cradle Power Steering Return Hose At Return Line Allow the remaining power steering fluid to drain from the pump and fluid reservoir through the removed return hose
Remove the accessory drive splash shield Accessory Drive Splash Shield
Remove the serpentine accessory drive belt from the engine Serpentine Drive Belt And Routing See Cooling, Group 7 for detailed removal procedure
Remove the power steering fluid supply hose coming from the remote fluid reservoir, from the fitting on the power steering pump Power Steering Hoses At Power Steering Pump Drain off excess power steering fluid from hose
Remove the power steering fluid pressure line Power Steering Hoses At Power Steering Pump from the power steering pump. Drain excess power steering fluid from tube.
Remove the power steering fluid return hose Power Steering Hoses At Power Steering Pump from the power steering pump. Drain excess power steering fluid from tube.
Remove the support bracket at the rear of the power steering pump attaching the pump to the rear of the engine Power Steering Pump Support Bracket
Remove the 3 bolts mounting the power steering pump to the alternator/power steering pump and belt tensioner mounting bracket Power Steering Pump Mounting Bolts
Remove the power steering pump from its mounting bracket.
The power steering pump is removed from the vehicle by pulling it out through the exhaust tunnel area in the floor pan of the vehicle.
If transferal of the power steering pump pulley is necessary, refer to DISASSEMBLY AND ASSEMBLY in this section of the MDS2.
INSTALLATION
Install power steering pump back in vehicle using the reverse order of its removal through the exhaust tunnel are of the vehicle.
Install the power steering pump on its mounting bracket. Install the 3 power steering pump mounting bolts Power Steering Pump Mounting Bolts Tighten the power steering pump mounting bolts to a torque of 54 N·m (40 ft. lbs.)
Install the support bracket attaching rear of power steering pump to engine Power Steering Pump Support Bracket Tighten the nut and bolt holding the strut assembly to bracket and the intake manifold stud to a torque of 54 N·m (40 ft. lbs)
NOTE: Before installing power steering pressure hose on power steering pump, inspect the O-ring on the power steering pressure hose for damage and replace if required.
Install the power steering fluid pressure line onto the output fitting of the power steering pump Power Steering Hoses At Power Steering Pump Tighten the pressure line to pump fitting tube nut to a torque of 31 N·m (275 in. lbs.)
Install the power steering fluid, low pressure return hose on the power steering pump low pressure fitting Power Steering Hoses At Power Steering Pump Be sure hose clamps are properly reinstalled.
Install the power steering fluid supply hose from the power steering fluid reservoir, on the power steering pump fluid fitting Power Steering Hoses At Power Steering Pump Be sure hose is clear of accessory drive belts and all hose clamps are properly reinstalled.
Install the serpentine drive belt Serpentine Drive Belt And Routing See Cooling, Group 7 for detailed installation procedure.
Install the power steering fluid return hose on the steel tube at the front suspension cradle Power Steering Return Hose At Return Line
Install a screw type hose clamp on the power steering hose to steel tube connection. Be sure hose clamps are properly reinstalled. Tighten the screw clamp to a torque of 2 N·m (18 in. lbs.)
CAUTION: The protective heat shield sleeves must cover the entire rubber hose and hose to tube connection portion of both the power steering fluid pressure and return hoses Power Steering Return Hose At Return Line This is required to keep the power steering hoses from becoming overheated.
When used, properly position the protective heat sleeves on the power steering hoses Power Steering Return Hose At Return Line Then, tie strap the heat sleeves to the power steering hoses to keep them in their proper position.
Install the exhaust pipe on the exhaust manifold. Install all exhaust system hangers/isolators on the exhaust system brackets.
Connect the oxygen sensor wiring harness to the vehicle wiring harness. Install wiring harness grommet in the floor pan of the vehicle.
Install the accessory drive splash shield Accessory Drive Splash Shield
Lower vehicle.
Connect the negative battery cable on the negative battery post.
Perform the POWER STEERING PUMP INITIAL OPERATION service procedure listed in this section to properly fill and bleed the power steering system.
Inspect for leaks.
It seems quite involved so I hope you are successful.
If instead of a square reservoir your vehicle has a round fluid reservoir then let me know as the '02 manual I have is different as to the procedure. I can't be sure which applies to your '00 but I think the reservoir 'shape' is the clue.

QUESTION: Hi Roland,
I have a round reserviour. I know it's weird to me b/c it's a 2000 but I think it might have been replace before and whom ever did it changed things they should have or something to that effect..go figure right?
Thanks for your help!
AnswerHi Robin,
No, it may very well be that the change occured in '00, I just don't happen to have the manual for that year, but rather '02. However, I do notice that it does give some info specific to the '01 model year about pump removal in this '02 manual, so I do agree with you that your '00 may have been modified. Maybe the best thing would be to xerox copy the pages from the '98 and '02 manuals and postal mail them to you. I don't have the pump removal procedure in digital format for the '02 manual, the only one like this I have is '04. The '99 text I sent you was posted last year by Kevin, the other 'expert'.
Let me know if you would like me to do any copying. The '02 procedure requires removing the wiper module, but it doesn't require removing any of the exhaust system, and there is a return hose to the reservoir from the steering gear which the '98 design doesn't have. Maybe those clues will tell you which set up you have.
