Cutlass Supreme V6-3100 3.1L MFI VIN M (1994)
Drive Belt Tensioner: Description and Operation
Serpentine Drive Belt
Drive Belt Tensioner Assembly
NOTICE: Routine inspection of the belt may reveal cracks in the belt ribs. These cracks will not impair belt performance and therefore should not be
considered a problem requiring belt replacement. How- ever, the belt should be replaced if belt slip occurs or if section of the belt ribs are missing.
A single serpentine drive belt is used to drive all engine accessories. All belt driven accessories are rigidly mounted with belt tension maintained by a
spring loaded tensioner assembly.
The indicator on the movable portion of the tensioner assembly must be within the limits of the marks of the stationary portion of the tensioner assembly.
Any reading outside of these limits indicates either a defective belt or tensioner assembly.
