Rerouting due to recall.
This belt is the correct belt for all 8th generation Civics. However, some of the 2006 Civics were initially produced with a different routing illustrated under the hood. If you follow that routing you will notice that you have several extra inches. This routing was found to place too much stress on the belt tensioner bolt, which resulted in the updated routing. I'm including an updated diagram as well as the service bulletin for the recall.. This is for Civics w/AC produced early in 2006. I'm not aware if this affects non-AC Civics.
