NOTE: The drive belt length inspection is done with the engine OFF.
The automatic drive belt tensioner is a spring-loaded device which sets and maintains the drive belt tension. The drive belt should not require tension adjustment for the life of the drive belt.
The automatic drive belt tensioner has a drive belt indicator mark. If the indicator mark is not between MIN and MAX, the drive belt is worn or an incorrect drive belt has been installed.
Locate the mark on the mounting plate of the drive belt tensioner. The indicator mark should be approximately between MIN and MAX.
Minimum belt length.
Maximum belt length indicator; install a new drive belt.
