can I just replace the belt or are there other components that need to be replaced at the same time?
I have 120K on my 96 A4.

 

tensioner
damper pulley
water pump
antifreeze
serpentine belt
and the timing belt

 

other than a time consuming process, is this relatively 'do-able' for a DIYer?

 

with the right info everything is possible

thanks very much for the link. Looks daunting but what the hell, why not go for it.

 

That tutorial is not for your engine. Check out the 12 valve forum on Audiworld for instructions. Just post for there for instructions. I don't have the link to the diagram anymore.

You'll probably also need a cam lock tool as well as the crank holding tool. It's pretty important to have them to keep the cams lined up with each other, otherwise you'll cause engine damage.

 

sorry didn't realise it was a 2.8 v6 12v
