Gates 04-07 Kenworth T800 Caterpillar C13 Diesel Fan Alt. & A.C. Belt Drive Tensioner

This is the Gates belt drive tensioner for the accessory belt system on 2004-2007 Kenworth T800 trucks equipped with the Caterpillar C13 diesel engine. This part is crucial for keeping the serpentine belt properly tightened, ensuring your alternator and air conditioning compressor run smoothly.

A worn or failing tensioner can lead to a loose belt, which might slip, squeal, or even come off entirely, causing a loss of power to essential components like the alternator. Gates is a well-known name in belts and related components, and this tensioner is built to handle the demands of a heavy-duty diesel application. It's designed to maintain consistent belt tension throughout its lifespan, which helps prevent premature belt wear and ensures reliable operation of your truck's accessories.

When replacing your belt tensioner, it's a good idea to inspect the condition of the serpentine belt itself. If the belt shows signs of cracking, fraying, or excessive wear, it should be replaced at the same time to avoid issues down the road.
