Installation Notes and Tips

Before installation, drain the shipping oil and refill the compressor with the correct amount and type of PAG 100 oil for the vehicle application. Replace the O-rings during service, verify the system is clean, and confirm the refrigerant charge is R134A before returning the Jaguar HVAC system to operation. Check belt alignment, connector fit, and clutch engagement during final testing.
