All engines use an automatic drive belt tensioner. No adjustment is necessary. If the tensioner is at Maximum travel, the belt is most likely stretched or the incorrect belt was installed.
Belt Tension Inspection
Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.
Drive Belt Routings
Removal & Installation
Disconnect the negative battery cable.
NOTEThe proper belt routing is included in this section, however, it is a good idea to make a simple drawing of the belt routing of your engine for installation reference before removing the belt.
- Rotate the drive belt tensioner to relieve the belt tension. The procedure is as follows:
Remove the belt from around the remaining pulleys.
- Position the belt around the pulleys in the proper routing with the exception of one pulley. It is easiest to keep the belt off of the easiest pulley to access. Hold the belt tight with your hands and using the proper tool for your engine, rotate the tensioner clockwise and place the belt around the final pulley.
Release the tensioner slowly until it sits firmly against the belt.
NOTEIf the tensioner does not touch the belt or the wear indicator marks are not within specification, the belt is routed incorrectly or the wrong belt has been installed.
- Connect the negative battery cable.
- Start the engine and ensure that the belt runs smoothly and no abnormal noises exist.
