8103010E51A1 AC Compressor is the core power component of air conditioning system for JAC HFC1048 light truck. Driven by engine accessory belt, it compresses low-temperature gaseous refrigerant into high-pressure high-temperature gas, pushing refrigerant circulation inside the closed AC loop to realize cooling effect inside the cab. This aftermarket replacement compressor fixes weak cold airflow, clutch slipping, abnormal metal grinding noise and refrigerant circulation failure caused by internal piston wear, leaking shaft seal and burnt electromagnetic clutch of old compressors. Stable refrigeration performance creates comfortable driving environment for drivers during high-temperature summer delivery missions.

Product Advantages High-precision internal compression structure delivers stable displacement and consistent cooling capacity. Cast aluminum alloy housing reduces overall weight and achieves good heat dissipation. Built-in electromagnetic clutch enables on-demand start-stop control of refrigeration cycle. Every compressor undergoes pressure tightness test, noise inspection and refrigerant oil filling before shipment, original mounting foot and port layout match AC pipeline directly.

Applicable Models Fit for JAC HFC1048 series light-duty commercial trucks, widely used for urban distribution and short-haul cargo transportation.

FAQ

Q1: What causes loud squeal immediately after switching on the air conditioner?
A1: Insufficient belt tension or worn clutch friction plate leads to slipping under sudden load.
Q2: Why is it necessary to replace the filter drier together when changing the AC compressor?
A2: Metal debris from failed old compressor easily blocks the drier and expansion valve, damaging the new unit.
Q3: What operation should be followed after compressor installation?
A3: Vacuumize the pipeline fully, add specified refrigerant and matching refrigerant oil, then test cooling function.
