I wouldn't say this was a very advanced job, but it does get fiddly working in the confined spaces so the instructions are quite detailed. Also be prepared to contort your arms into horrible positions and make sure you have a socket-set with at least 5 inches of extra reach AS WELL as a 12mm and 14mm open-ended spanner, with as low a profile as possible.
PROCESS:
2. Remove the two bolts holding the pulley-cover in place using a 10mm wrench, then loosen the bolt on the right-side alternator bracket using a 12mm wrench a couple of turns so the pulley-cover can be slid out. Turn the pulley-cover over and push the plastic-stud that holds the throttle-cable clip out of its hole.
3. Using a 12mm open-ended spanner, loosen the far nut on the throttle-cable where it sits in the bracket as far as it will go so the cable can be pushed back and lifted out of the bracket. Swivel the cable so it clears the PAS-pump area and fasten it with a cable-tie.
4. Using a 14mm open-ended spanner, loosen the union-bolt that attaches the metal-pipe to the port on the left side of the PAS-pump. Only crack the bolt off a couple of turns so no fluid spills, but the bolt can be removed easily once the pump is no longer fixed in position.
5. Remove the bolt that is threaded through the long adjusting-bolt that moves the alternator up and down. There is no need to slacken the adjusting-bolt - once the holding-bolt is out, the alternator should drop down fully anyway.
6. Lower the alternator until the belt becomes loose enough to be slid off the pulleys.
7. Remove the 3 bolts holding the PAS-pump in place using a 12mm wrench. There are 2 bolts to the front of the pump, beneath the pulley, which are easy to find, but there isn't a lot of room to turn them. The third, to the rear-right of the pump can be accessed from above, but you'll need at least 5" of reach on your ratchet.
8. Now the PAS-pump is free, remove the union-bolt from the pipe on the left side and lift the pump out. It's best to wrap a cloth around the union-bolt when removing the pump to catch any PAS-fluid dropping into the engine, although the pump shouldn't spill a lot anyway. **Plug the end of the metal-pipe.
9. Install the new PAS-pump, replace the pipe/union-bolt and insert the 3 bolts holding it in place.
10. Slide the new belt into position on the 3 pulleys. Lift the alternator until the belt is tense and replace the bolt that holds the adjusting-bolt in place. Now tighten the adjusting belt to the torque mentioned in the Workshop Manual [here] or just until the top stretch of the belt can be moved about 5mm up or down.
11. Replace the rubber return-hose and finger-clip to the top of the PAS-pump.
12. Snip off the cable-tie, swivel the throttle-cable back into its natural position in the bracket and retighten the 12mm nut on the far side.
13. Add PAS-fluid to the pump and allow it drain into the system and air to come out until the fluid reaches the measuring-scale on the cap.
