Lightbulb 958 Cayenne DIY: How to change a V-belt and water pump (3.0 diesel)

Right. So this is what I did.
1. I loosened the 3 bolts holding the water pump pulley.
2. Theres a large rubber hose at the front of the engine, remove it to give yourself more room.
3. I connected my T60 to the serpentine tensioner and pulled it up (clockwise)
4. Belt is now loose, so you can easily pull the belt off.
5. Now undo the 3 bolts you loosened and remove the pulley.
6. Now water pump is exposed. Lets first remove coolant cap to release any pressure.
7. Undo water pump bolts, about 10 bolts.
8. Pump may be stuck on, try use a crowbar or similar to gently prise it off.
8. Coolant gushes out. Once stopped gushing out, clean up the area and don't get oil or dirt in the coolant system.

Then fit all back in reverse.

NOTES:

-when tightening the 3 pulley bolts, try put some thin screwdriver or thin bar into the 2 holes to lock the pulley in place. There is a special tool for this but you don't need to buy this tool.
-Also by letting the coolant gush out from the water pump means you only lose approx 2.5L of coolant. If you want to do a proper coolant flush completely prior to undertaking the job then remove a hose near the bottom of the engine bay and let the coolant flush out. By doing this you'll need much more coolant to fill the system up (I think its 11L).
-V-belt i used was a contitech 6PK2523 (original from factory was also a contitech) I paid just 14GBP for it on amazon (but ebay has them for 20GBP)

I've uploaded official documents (totally forgot to look at this before doing the job.. haha)
