259-7244 Denso 10S17C A C Compressor — Cat 3066 307D

This Denso 10S17C A/C compressor is the heart of the vehicle's air conditioning system, responsible for circulating refrigerant to cool the cabin. It operates under high pressure, converting low-pressure refrigerant gas into a high-pressure liquid, and is built with durable materials to withstand demanding conditions. Operators will notice a lack of cool air, unusual noises from the compressor pulley, or a burning smell if this unit fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most immediate symptom of a failing A/C compressor is a significant reduction or complete loss of cool air from the vents. You may also hear loud grinding or rattling noises originating from the front of the engine. If left unaddressed, a seized compressor can cause the drive belt to break, disabling other essential engine accessories.

Installation Tip

Before installing, ensure the A/C system has been thoroughly flushed to remove any debris or old refrigerant oil. Never run the compressor without proper lubrication and refrigerant charge, as this will cause immediate damage.

Service Note

It is highly recommended to replace the A/C receiver drier and expansion valve (or orifice tube) when replacing the compressor.
