The transmission lines are easy. Just push the line in, like you're trying to push the line into the rad., then take a small flathead screwdriver to gently pry the small C-clip wire clip out from the side. Be careful not to loose it. Once the wire C-clip is removed, just pull the trans line out. Same for both top and bottom. There is some plastic holders on top that hold the ac condensor on the front of the rad. I thinki they are 10mm. not positive though. The big harness is held in by plastic clamps, just pop loose with a screwdriver.
