Drive Belt: Testing and Inspection











Checking Drive Belts

WARNING: Be sure to perform when the engine is stopped.
Make sure that indicator (single line notch) of each automatic tensioner is within the allowable working range (between three notches).


NOTE: Check the automatic tensioner indicator when the engine is cold.

The indicator notch is located on the moving side of the tensioner. Visually check entire belt for wear, damage or cracks.

If the indicator is out of allowable working range or belt is damaged, replace the belt.

Belt tensioning is not necessary, as it is automatically adjusted by auto belt tensioner.
