CO 4546 Sanden SD7H15 Compressor Assembly

It’s a compressor assembly designed to restore cooling performance in a vehicle air conditioning compressor system. This Sanden SD7H15 compressor is commonly used in truck applications where reliable A/C operation is critical. Matching the correct part number and port/pulley specs helps ensure proper fit and function.

Confirm the part number and cross-references (including UAC CO 4546) against your existing unit or your vehicle’s OEM/aftermarket interchange. Also compare key specifications like 6 grooves, 122 mm pulley diameter, and 21 mm suction port diameter. If your truck uses a Sanden SD7H15 compressor with the same configuration, it’s typically a match.

It’s best practice to address system contamination and wear items when installing a truck A/C compressor. Many technicians replace the receiver/drier or accumulator and the expansion device, and flush the lines to protect the new compressor assembly. Using the correct refrigerant oil amount and verifying there are no leaks helps the Sanden SD7H15 compressor last longer.
