I had to do a power steering pump replacement on my 2000 LW2 and took some pictures as I went to do this write up.

The following information pertains to my vehicle only, and therefore following my advice is under your own risk.

This information applies to the V6 L Series power steering pump.

It was about time to change my power steering pump, it has been making noise since the stone age, and while I had to do the water pump I decided to do the power steering and get it over with.

Here you can see the intake filter housing, take note of the sensor plug, two metal clips on the right side, and the intake duct clamps

First you're going to want to unplug the sensor plug from the air intake plastic duct. Youll also want to loosen the clamp that is attached to the intake plenum with a flat head screwdriver. There is a hose near the top that clips in lightly to the top of the filter housing, unclip it. Lastly, unclip the two metal clips on the right side of the intake filter housing. The housing cover swings open from right to left, so lift the right side and slide it upwards and you'll have it off.

A wild filter appeared!

Now you remove the filter.

Plastic, plastic, plastic

Now there is a screw on top where the intake housing is held to the car. Remove that screw and youll be able to slide the whole assembly upward and out. Be careful of the lower intake duct as you do this. In my case, the screw was stripped and I had to force it out but you should have an easier time.

Here is where you're at

Now you can see where you need to work. The top pulley closest to you. In my case I was missing a bolt, so ignore that. You're going to want to use a female torx to loosen these 3 bolts, I got away with a 8mm socket. You only want to loosen it.

Serpentine belt off the pulley

Then take a 15mm to the tensioner (top pulley, furthest away from you) and tighten it to loosen the serpentine belt tension. As you do that, pull the belt off of the power steering pulley. When you're done that, you can take off the 3 bolts holding on the power steering pulley and remove the pulley.

And I'm missing another bolt, this time holding the power steering pump on.

Now you're going to look on the other side of the upper rad hose, and you'll see a hose that is covered by heat shielding. Pull back the heat shielding, and you'll see a hose held with a clamp. This is the low pressure power steering fluid return line. Prepare for fluid to escape, I used a bag tied to the end of the hose to keep it from making a mess.

Now you're going to take off the fluid feed line to the power steering pump, located directly above the pump and has a hard line going to it with a 18mm nut holding it on. Loosen the nut, prepare for some fluid, and remove it from the pump.

[size=1]Here you can see the 18mm nut loosened off on the top right of the pump

Now you just want to remove the three bolts that hold the pump to the car. These are located on the top, left and bottom of the pump. These are 13mm bolts, and kind of a pain in the butt to get at.

Oh hey a missing bolt! But this shows the top and left locations of the bolt, and the third bolt is right under the pump

Now you're almost ready to put the new pump on. You'll notice that the pump comes with a very small O-ring. This goes on the line with the 18mm nut you loosened off. A picture below shows the black O-ring on it. It's the blurry part, go figure.

Sorry for the blur

Install the new O ring by removing the old one gently with your fingers, and putting the new one on.

Installation is reverse of the removal. Overall, it's a fairly easier job than I thought, just make sure that you have the proper equipment to grab the fluid that is bound to come out. I used a plastic sheet below the car and two drain pans and two bags, one per disconnected hose. Also be aware that new pumps come pre filled with fluid, so don't tip it over. Have fun!
