Overview
The Sunair CO-6248CA is a CP16 TM/CP-style A/C compressor engineered for heavy-duty vehicle climate systems. It features an ear-mount body for secure bracket alignment and a PV8 serpentine clutch measuring 119 mm (4.69 in) to match common OE belt routing and speed. A 12 V electromagnetic coil with a single bullet terminal simplifies electrical hookup. Compatible with R134a refrigerant and PAG 46 oil, this unit integrates cleanly into standard fleet service practices.

Performance and compatibility
The PV8, 8-rib pulley delivers robust belt engagement suitable for high-accessory-load environments, while the 119 mm diameter helps maintain proper compressor speed and system performance. The CP16 architecture aligns with widely used TM/CP-style installations across heavy-duty trucks and related platforms. Cross-reference coverage with leading aftermarket and OE suppliers helps streamline sourcing for mixed fleets and simplifies standardization.

Service notes
Verify mount style, pulley diameter, groove profile (PV8), and coil voltage (12 V) prior to installation. Use PAG 46 oil and charge with R134a per the vehicle manufacturer’s specification. Best practice is to replace the receiver-drier/accumulator and orifice tube or expansion valve, flush the system, and evacuate before charging. Follow OEM torque procedures and electrical polarity for the bullet terminal connection.
