Does the air box have to come off in order to get enough room to get the 3/8 drive ratchet in the square hole of the tensioner? I'm doing this tonight and I want to remove as little as possible as I'm in a huge hurry tonight.

And PS... sorry for digging up an old thread... I was just using the search button and this is the only one that showed up that I could find for "04 Ranger Serpentine belt replacement"
