Installation Notes and Tips

Verify the vehicle’s refrigerant system uses R134A and confirm PAG 46 oil specification before installation. Match the pulley groove count, outside pulley diameter, and connector layout to the original compressor on the vehicle. Replace the seal ring as required during service and inspect the rest of the A/C system for contamination, leaks, or restricted flow before charging.

Quality Assurance

Bosch subjects this compressor line to release testing that includes endurance, performance, vibration, leak, salt spray, and noise evaluation. The result is an OE-focused replacement built to meet the dimensional and functional requirements of the original application.
