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.





NOTE:
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.
