Product Description

This DZ15221840303 air conditioning compressor assembly is a dedicated cabin cooling component matched for heavy trucks equipped with ISM series engines. Manufactured with high-precision die-cast aluminum housing, it acts as the power core of the vehicle air conditioning system to compress R134a refrigerant and realize refrigeration circulation inside the cab. It comes factory-equipped with a multi-groove electromagnetic clutch pulley and complete corrugated wiring harness with color-locked waterproof plug. The internal chamber is pre-filled with specified PAG lubricating oil, which saves maintenance filling steps. All mounting lugs, refrigerant inlet/outlet ports and electrical interfaces fully conform to OEM dimensional standards, supporting direct bolt-on replacement without extra modification during AC system repair.
