6.6. V-belts (1) Change the V-belts if necessary If in the case of a multiple belt drive, wear or differing tensions are found, always replace (2) Checking condition the complete set of belts. Check V-belts for cracks, oil, overheating and wear. (3) Testing by hand V-belt Press here The tension is correct if the V-belts can be pressed in by about the thickness of "Y" the V-belt. (no more midway between the belt pulleys) Water pump pulley A more precise check of the V-belt Alternator pulley tension is possible only by using a V- belt tension tester.
