So my 01 has 100K on the clock now, and a sqeaky serpantine belt and a loeaking power steering pump.

So I have bought new serpentine belt, AC belt, t-belt, tensioner, water pump, power steering pump, a Chilton Guide and some nice Axxis front pads. Any one have a good walk through or DIY on the T-belt and removing my S4 bumper?

this one on audiworld is probably the best out there:

i printed it out and followed the steps. if youd like i can look into uploading all the pics i took. i tried to take a pic every time i removed a screw so id know where everything went back.

edit: here i uploaded a bunch of pics. note that in the middle there i did the cam seals which you probably wont be doing.

i'd recommend being very organized, i lined up every screw/bolt i took off in a line on the curb so i could put everything back on in the same order they came off:

Just looked at this how-to. It's very thorough but where the hell is the other cam gear?

what? are you asking why theres only one cam sprocket? it's because our cams are attached by a chain. the exhaust cam is spun by the timing belt and the intake cam is spun by the attached chain. you can see the chain on the left here:

So is the still an interference type motor? i.e. t-belt goes so do valves.

That was my question. I've never seen anything like that before. Always two cam gears.

im pretty sure it's done what way because the car controls timing through that chain by delaying or advancing the intake cam.
