What is included in a Cloyes timing belt kit?
Cloyes timing belt kits combine a timing belt with application-specific tensioners and idlers. These components work together to maintain belt tension and accurate engine timing. Check the product listing for the exact kit contents.
Why replace the tensioners and idlers with the timing belt?
Tensioners and idlers help support the belt and control its movement. Worn components can compromise the operation of a new belt. Cloyes recommends replacing them when the timing belt is replaced.
