Getting off the freeway one night I came to a stop light to suddenly hear loud power steering whine, and had bad vibration in the steering wheel. Checked the reservoir and noticed the fluid was foaming. It was leaking from the pulley shaft. Turned out to be caused by shot bearings pump had 90k miles on it. You can find re-manufactured pumps online for around $400 after $100 dollar core refund. A brand new pump through dealership costs $650 dollars. I decided the extra couple hundred was worth a new unit, and had it shipped overnight for free through my local dealer. For the most part removal, and installation was easy. Having two people helps, but it is a one person job. Lets start with a list of tools, and supplies.
Power Steering Pump (112 466 01 01)
Power Steering Fluid (Q-1-46-0001)
Reservoir Gasket (000 466 18 80)
Oil Container
Paper Towels
Needle Nose
Large Wrench
Shorty Ratchet
Medium Ratchet
3" Extension
Internal Star or 20 Point Sockets
Standard MM Sockets
Two Jacks & Stands
Two Wheel Blocks
Remove front engine cover by pulling it up off the pressure clamps. Remove right side air intake tubing. It simply pulls off both ends. Jack up front driver side, and place jack stand. Remove front bottom skid plate six 8mm screws. There should be a substantial amount of power steering fluid build up on the top side of the under-body panel. I also took the time to try and clean up all the mess made by the leaking PS fluid over several months. You should expect to see a lot of sludge build up around the pump on the engine.
Note: In the above photograph I had removed the front side of the pump. This is not required. Wanted to open it up, and check the gaskets. The two sections are held in place by four bolts on the front side of the pump.
To remove the fluid reservoir first take out locking ring where reservoir connects to the pump. Use a pair of needle nose pliers to grab the ring tightly, and pull it straight out. Now unbolt the reservoir assembly with the single external star bolt. Unscrew clamp holding the tube connected to reservoir in place, and pull off. If you don't have a pump to siphon the fluid out just plug the opening when you pull it, and drain into oil container.
There are two front star bolts, and three rear star bolts holding the pump in place. Take belt off the tensioner pulley by loosing tensioner (external star bolt). Do not completely remove belt off other pulleys. To remove the front bolts on the power steering pump you must first take off the power steering pumps pulley, and the tensioner pulley. Three bolts hold the PS pulley in place, and a single 14MM nut holds the tension pulley. Use a large wrench to unbolt the main metal power steering line from the pump. There are two metal washers on each side of the bolt.
The two front star bolts are easy to access. However, the three rear star bolts are not so easy... You have to work in a very limited amount of space. I was able to find a shorty 1/4 ratchet small enough to use at Sears. Being that my star sockets are 3/8, and there is no space to use an adapter I also bought a set of 20 point sockets all 1/4. These will work on the star bolts. The bottom inside bolt is the hardest to get at. The space is very limited due to that black piece of the A/C compressor being in the way.
When you get the old pump removed just reinstall everything in the reverse order. Make sure to replace the reservoir gasket. I also used a new locking ring for the reservoir. I'm sure the old one can be used again.
For pump bolts first place top front, and then rear bracket. Do not tighten bolts completely. Bottom front, top rear, and then the hard to get at bottom rear bolt. Tighten all bolts...
The locking ring on fluid reservoir can be a little tricky. Place the gasket onto the pump first, and push the reservoir onto the gasket. Once it's in place the slots will nearly line up. Add the star bolt, tighten completely, and add the locking ring.
Add fluid to the power steering reservoir until it stops bubbling, and reads at 20C Max. Turn the pump by hand for a few to clear air. Top off reservoir as needed. Block up rear tires, I used bricks, and jack up the passenger side. To clear air from the lines, and rack manually turn the steering wheel with engine off lock to lock forty times, or until you no longer see bubbles.
