Hi,

the video gives you a step by step tutorial how to replace the timing belt at the Audi 100 / A6 (C4) having the V6 engine with 2.6l or 2.8l. This repair requests special tools, but you may find them in the web.


The video has a German soundtrack, but English subtitles are available. If you don't see them by default, watch the video directly at YouTube and press the subtitle button below the frame.

Enjoy it,

Good video. However, he should have also changed the water pump and thermostat while he had it disassembled - much easier than going back and tearing down again.

Hi,

last time I have done this, I replaced my good old water pump by a new one. The new one died after 30000 km only and I had to do all again on a road in the mountains. Since that expierence I replace only broken parts.

Regards,

Jürgen

very smart to replace the water pump when its already broken

Try one thats not garbage quality. I have had great luck with Graf and Hepu brand water pumps. Meyle, GMB, parts store pumps, are garbage. I would never do a timing belt and not do the thermostat and waterpump, what a waste of time.

According to Blauparts you should always replace the water pump when you do a timing belt change, as a worn pump will develop play in the bearing which may allow the timing belt to grind and result in a catastrophic failure. And they say that the impeller of a worn pump may grind metal due to play in the bearing.

Would an experienced owner detect a leaking water pump before catastrophic failure were allowed to occur? The water pump bearing is the seal, so we know that if it starts to leak, the bearing is worn and the pump is shot. If it doesn't leak we can assume the pump is OK.

But I know I wouldn't like to tear down the engine twice per timing belt interval only to squeeze a few thousand km's out of the old pump.
