Description
Used A/C compressor Sanden SD6V12 1439F (1439) designed as a direct-fit replacement for many PSA Citroën and Peugeot vehicles. This unit is supplied as a used part with a functional warranty and is commonly identified by part numbers 9646273380, 6453KS and additional number 6453LN. The compressor provides reliable pressurisation of refrigerant to deliver effective cabin cooling.
The compressor is compatible with typical R134a air conditioning systems and requires PAG 46 oil. Recommended oil charge for this unit is 135 ml. Common failure modes include shaft seal leaks, clutch wear, bearing failure and contamination from system debris. Typical symptoms of a failing compressor are reduced cooling performance, unusual grinding or rattling noises, clutch slipping or visible refrigerant/oil leaks.
Installation should be carried out by a qualified technician or experienced DIY mechanic. Typical replacement steps: safely recover refrigerant using the correct equipment; disconnect battery; remove drive belt and electrical connectors; unbolt and remove the old compressor; replace O-rings and seals with parts lubricated with PAG 46; install the new compressor, refill with specified oil volume (135 ml), evacuate and recharge the system to the manufacturer’s refrigerant specification; finally check for leaks and verify operation. Replace the receiver-drier/desiccant and any contaminated lines if the system shows signs of contamination.
Regular maintenance of the cooling system, correct belt tension and timely replacement of the receiver-drier will help extend compressor life. When searching for a suitable replacement, always verify fitment by part number to ensure compatibility with your specific vehicle variant.
