AC Compressor 13412251 for Opel Astra J/Insignia A/Zafira C (P10/G09/P12) 2010-2018 1.6L

Our air conditioning compressor for 13412251 is made to the original drawing and goes straight on to OPEL ASTRA H, ASTRA H Estate and ASTRA H Estate Van without modification.

The compressor is driven by the engine belt through an electromagnetic clutch, and it is the only part of the system that does the work of moving refrigerant. The unit draws low pressure vapour from the evaporator, compresses it to high pressure, and discharges it to the condenser, which is the whole reason the cabin gets cold.

The fitment we have confirmed runs from 2004.01 to 2018.04, split across 12 references in the table, so check the chassis code against the list before you order.

The clutch coil is sealed against the engine bay environment and the pulley is aligned to the original belt line. The housing is die cast aluminium and the shaft seal is a double lip design rated for the pressures the system runs at, with the pulley and clutch fitted and tested.

Cold air that fades as the engine speed rises is a sign of a compressor that is worn internally rather than a refrigerant leak. Metal debris in the system means the compressor has failed internally, and the condenser and the expansion valve have to be flushed or replaced. A compressor that runs continuously and never cycles can be an overcharge or a failed control valve, not necessarily the compressor itself.

Flush the system and replace the receiver drier and the expansion valve whenever a compressor is replaced, or the debris will destroy the new unit. Add the oil charge specified for the application, and do not mix oil types between the old and the new compressor. Evacuate the system for at least 45 minutes before charging, and leak test at the ports after charging. Samples are available before a bulk order, and private label packing can be arranged.

The reference 13412251 is stamped on the box, so the part that arrives is the part that was quoted.
