Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
Tow truck to the closest dealer and they fixed it directly (had a pump on stock, and squeeze me in between other cars, Great service!), after a few hours I was on my way again with a new water pump.
Hi guys,
The water pump went bad on my 996 C4, 70k miles. Bearing shot, pulley wiggles and signs of coolant leaks from the bearing.
Bought a new pump and gasket and installed it this weekend.

996 water pump replacement procedure
Wow, great job! Nice detailed pics and instructions. Thank you!
Now, the question remains...do I have the guts to do it myself when mine needs replacing...
I did have two "longer" 10mm bolts, but I think one of the goes on the engine carrier... So only left with one bolt, which I believe went into the left upper side of the water pump perfectly.
I just had mine replaced last thursday on my 996 C4 (-99) after 70700km. Broke down on the highway, made a lot of noice....
Bearing completely broken, turbine wheels on waterpump damaged and fallen into cooling system.

Insult to injury / Murphy's law....
How long does water pump replacement take? I will be attempting this DIY over the weekend.
On the way home from the my dealer (approx. 2.5 hours one direction) I had the bearing / seal go out. Initially squealing followed by clunking, and finally water loss. At least I was about a mile from the house.....
