Disassembly and Replacement of Water Pump

Model: Audi A6 C5, MK 2 - Years 1997-2004
Part: Pump

Open the hood and remove the protective covers of the timing belt located at the front of the engine; remove the timing belt tensioner to release the belt from the pulleys.
Then, unscrew the mounting bolts of the water pump, pull it out from its seat, and carefully clean the mating surfaces to ensure a perfect seal for the gasket. Next, install the new pump with the corresponding gasket (it is also suggested to apply gasket sealant on the gasket) and tighten the mounting bolts.
Reinstall the timing belt on the respective pulleys and the tensioner, paying attention to the timing marks.
It is recommended to perform this repair only if you have good mechanical knowledge, as replacing the water pump requires removing the timing belt, and a simple mistake could severely damage the engine.
