Although Haynes rates this as a 4 spanner out of 5 difficulty degree, it really isn't that hard to do - but it is much work and will take some time.
Start by removing the upper and bottom tubings from the rad. Depending on how severe the water loss was when the water pump broke down, there will be some spillage...
Remove the plastic cap that guides the flow towards the rad, by taking off both top clips.
Both belts can be removed, one is adjusted by the PAS pump, the other by the alt.
Unscrew the large nut from the fan (Left-hand thread!) with a 32 and 36 mm spanner.
I was told to keep the fan upright (instead of lying it flat), due to the viscous coupling.
The pulley comes off with 4x T30 screws.
Open up all the small clips that hold the timing belt cap in place, and take off the front part.
Line up the timing belt on top and bottom points (17 mm nut on the end of the crankshaft).
There is a (10 mm?) nut that keeps the plastic part (behind the water pump) in place, undo this one.
Undo all three 6mm Allen bolts that keep the water pump in place.
Turn the water pump anti-clockwise to loosen the tension on the timing belt.
Take out water pump, clean up the housing inside (I used steel wool), smear vaseline on the side where the rubber O-ring (gasket in english?) makes contact, and put some vaseline on the water pump itself behind the O-ring.
This is how mine looked like:
After the cleaning up:
Re-fit the timing belt (making sure it's correctly timed, and tensioned properly - see
here )
Assembly time, not that hard... see above in reverse order
While you're at it, flush out all the coolant - mine was rather dark, re-attach bottom and top tubings, and re-fill.
disclaimer: I hope I didn't miss anything, this is how I done it and I'm sure there are better descriptions out there, use this one at your own risk...
