CM COMPRESSOR A/C Receiver Drier for Kenworth T660 T800 W900 C500 - OE K251571 Direct-Fit, Moisture & Contaminant Protection

CM COMPRESSOR A/C Receiver Drier compatible with Kenworth T660, T800, W900, C500 (OE# K251571) is a direct-fit replacement component designed to trap moisture and contaminants from your truck’s air-conditioning refrigerant circuit.

If your Kenworth’s A/C has been opened for service, shows reduced cooling efficiency, or you’re rebuilding the system, replacing the receiver drier is a recommended step. This aftermarket unit matches the OE mounting and connection points for a trouble-free swap on popular Kenworth models and helps protect the compressor and expansion components by capturing water, acids and particulate before they circulate.

What role does this receiver drier play in a Kenworth A/C system?

The receiver drier stores and filters refrigerant while removing moisture and small debris. It sits downstream of the condenser and upstream of the expansion valve, serving as a short-term reservoir and desiccant housing to keep the system dry and clean.

• Captures moisture to prevent ice and corrosion in the system
• Filters particles that could clog expansion components
• Provides temporary refrigerant storage for steady flow

Will this unit fit my truck models and the OE K251571 specification?

This receiver drier is manufactured to be compatible with Kenworth models listed and to align with OE# K251571 mounting and connector layout. It’s supplied as a direct-replacement option for technicians and owners seeking a like-for-like swap.

• Compatible models: Kenworth T660, T800, W900, C500
• Matches OE mounting and service connection locations
• Suitable when replacing after system repairs or compressor replacement

How should I install and maintain the replacement receiver drier?

Installation is straightforward for a qualified technician: evacuate the system, remove the old drier, transfer or replace any brackets, install the new unit, and follow refrigerant service procedures. After installation, perform a leak check and proper evacuation before charging the system.

• Evacuate A/C system fully before removal
• Replace O-rings and follow torque recommendations for fittings
• Vacuum and leak-test the system before refrigerant recharge

How will replacing the receiver drier affect A/C performance?

A fresh receiver drier helps restore consistent refrigerant flow and reduces the risk of moisture-related faults, which can improve cooling steadiness and prolong component life. It won’t fix unrelated mechanical issues, but it removes one common failure point in documented service procedures.

• Reduces moisture and contamination that degrade cooling efficiency
• Helps prevent expansion valve and compressor blockages
• Supports longer service intervals when installed correctly

Who is this for? This CM COMPRESSOR receiver drier is intended for fleet managers, independent diesel technicians, and Kenworth owners performing A/C repairs or overhauls. It’s a practical replacement part when servicing the condenser, compressor, or when the system has been opened to service—particularly on T660, T800, W900 and C500 chassis that require the OE# K251571 layout. If you need a like-for-like aftermarket component to restore system reliability and protect costly A/C elements, this receiver drier is a straightforward, service-oriented choice.
