Quick overview of what is involved in replacing the oil cooler gaskets and starter in a 2005 Audi S4. Audi 4.2 V8. Very common oil leak from the oil cooler.
Went out yesterday to take the kids to baseball and the engine sounded terrible. Checked oil, needed some...when I added the oil, I looked under the car and it was coming out from where the oil cooler is...One or both of the o rings must be bad so Looks like this is what I'm in for. Thanks for posting the video.
Thank you for this- I have been dreading needing to replace to o rings, you have inspired me and it actually does not look so bad now that you have given me better overview on the engine.
Just PRAY you don't have to replace the alternator. Fun fact. Zero room. And 2 rubber/hard pipe coolant lines goes INTO and OUT of the ALTERNATOR. It's a water cooled alternator lol. Im a big healthy guy. years and YEARS of wrenching on VAG. The tool I had to make to be able to get a 5mm Allen onto the coolant pipe hold down was insane. Took a torch, wrenches, all thread, Allen's and a welder and a vise😂 allens.. multiple because it was so tight had to make 1 that broke it loose, one that could loosen it most the way. And one that could get the last 1/4 of rotations out because your hand DOES NOT FIT if you're like me lol. Worth it. Low mile Noggy/Noggy sedan. Full non res-miltek exhaust. Jhm tune (p.o. family) I don't really mess with the NA motors. No fun there
I don't understand why Audi can have this type of engineering errors (if you can call it errors) to its customers that to replace some simple gaskets an enormous amount of mechanical work has to be moved! even for a customer it would represent a huge repair expense!!
