About Flat Rate Shipping
Please note that there are two options when installing a belt with
this unit. You can use either a 12 point 17 mm box wrench/socket or a
T-60 Torx head when installing the serpentine belt.
you have had premature failures of this tensioner or the serpentine
belt has broken or been thrown, you most likely have a failed alternator
pulley. The alternator pulley is a declutching pulley and has a
one-way clutch mechanism to minimize belt flutter. Belt flutter places
stress on the entire belt drive system and the tensioner acts as a
spring-loaded shock absorber. If the declutching pulley has seized, it
will greatly shorten the life of the belt tensioner and often causes the
pulley to break off or a fracture of the pulley arm. Replace the alternator pulley or the alternator to solve this problem.
