Great idea re transmission oil; not sure when that was last performed. Forgot to mention, plugs and coils were changed at 100k. Thanks!

Planning to undertake a couple of slightly larger (for me anyway) proactive projects on my 2004 C4 w/123k miles: AOS and oil cooler. AOS was replaced 7 years ago. Oil cooler is original. I'd say I'm a 2+ on the 4-wrench difficulty scale. Wondering if there's any priorities that I should add while I ...

'01 C4 cleaned up for weekend driving

Well now that I completed the project, I'll answer my own question

Yes, an O2 socket is necessary; an offset version. And nice to have a breaker bar handy as well as a wobble socket.

Hi all, replacing all 4 O2 sensors on my 2001 C4. Seeing conflicting info on the recommendation for an O2 sensor socket vs a 22mm fixed/adjustable wrench. Can all be accessed with a wrench? Would job be easier with a socket? Thanks.

Might not be possible but would like to have the part on hand when I remove the door panel. Any thought on what the ...

Thanks for confirming the clamps. Haven't run across that before. Have aluminum connector on the way. My concern is pieces of the old plastic connector are down in the hose and I would like to flush them out before reconnecting. Realizing there would be a coolant loss, can I start the car to run ...

Thanks. I had a hard time describing it because I only know enough to be dangerous.

Removed airbox and noticed the connecter that connects the water line to the AOS became brittle and broke. I think pieces of the connecter dropped into the lower line. Clamps for this line look like a 'one-and-done' type; can't figure out how to open them. If I briefly start the car, will this flush ...
