Just replaced my AOS-worst job ever!
 

I read every article and tip I could find on replacing the AOS. What a miserable job! I have small hands and even had the flexible hose clamp tool and it was still a struggle for me to get into that tiny space. If the one I put in ever fails, I'm burning the car.

I thought about doing mine (burns about a quart over 5k miles) while I was replacing my starter. Did all the reading, got under the car, looked at it...and said f$%# it. I'll wait for when it becomes necessary....

I did mine too, and don't remember it being so bad. It was a little frustrating, though. We had two people, and we took off the wheel, lifted the right side. Somehow we managed to get it in there.
