The accessory belt connects the engine pulley to the pulleys of various accessories: air conditioning compressor, water pump, alternator. It is made of flexible materials like rubber or fiber and is powered by the engine's force.

It drives the different equipment through the pulleys. When it is broken, it must be replaced because it causes the suspension of operation.

To change it, lift the vehicle and remove a tire, identify the type of tensioner pulley, and remove the accessory belt, then check the condition of the pulleys and rollers by turning them by hand.
