Air Conditioning Belt
Mitsubishi FUSO®

The Air Conditioning Belt (part number SSA921A031AJ) is a component of the truck's air conditioning system that drives the compressor. It is a rubber belt that wraps around the pulley of the air conditioning compressor and connects it to the engine's crankshaft pulley. When the engine runs, it turns the crankshaft, which in turn spins the air conditioning belt and makes the compressor run. The compressor then circulates refrigerant through the system to cool down the cabin. Over time, belts can wear or become damaged, leading to decreased performance or even complete failure of your air conditioning system. As such, it is important to inspect and replace your truck's air conditioning belt as part of regular maintenance to ensure optimal operation of your vehicle's climate control system.
