REPAIR PROCEDURE
1. Remove the original drive belt:
^ Refer to page 4-40 of the 2006-2007 Civic Service Manual, or
^ Online, enter keywords DRIVE BELT, and select Drive Belt Removal/Installation (R18A1 and R18A4 Engine) from the list.
2. Install the new drive belt, and route it as shown.

Use an appropriate tool for added leverage when setting the wrench on the auto-tensioner. The tensioner is hydraulic and should be moved slowly to relieve pressure on the belt. Applying excessive force to the tensioner can cause breakage.
