I bought a new A/C compressor and I heard that it needs to first be injected with oil then you can add the Freon. Can you please tell me where it goes? The oil and the freon? I bought the hose to connect, but the auto parts person said that you need to add it to the low side not the pressure side. I don't know where that is located. The hose nozzle does not fit the top side under the hood and I don't know where the other side is located. Please help!

Thank you very much!

Hello

Air Conditioning (A/C) System Recovery, Evacuation and Charging
WARNING:A/C refrigerant can be extremely hazardous and failure to follow the equipment manufacturers instructions may result in personal injury.

WARNING:Jaguar Cars Limited recommend the use of a charging station to carry out recover, evacuation and charging of the refrigerant system. Follow the manufactures equipment procedures and instructions. Failure to follow these instructions may result in personal injury.

CAUTION:The A/C refrigerant analyzer must be used before the recovery of any vehicle's A/C refrigerant. Failure to do so puts shop bulk refrigerant at risk of contamination. If the vehicle A/C refrigerant is contaminated, refer the customer to return to the repair facility that carried out the last A/C repair. If the customer wishes to pay the additional cost, use the A/C recovery equipment that is designated for recovering contaminated A/C refrigerant. All contaminated A/C refrigerant must be disposed of as hazardous waste. For all equipment, follow the equipment manufacturers procedures and instructions.

CAUTION:Do not add R-12 refrigerant to an A/C system that requires the use of R-134a refrigerant. These two types of refrigerant should never be mixed. Doing so may cause damage to the A/C system.

Connect the charging station. For additional information, refer to the manufactures equipment instructions.
Recover the refrigerant. For additional information, refer to the manufactures equipment instructions.
Carry out the required repair procedure. Refer to AIR CONDITIONING
Add the required amount of oil to the A/C system depending on the repair procedure.
Refrigerant Oil Adding
Evacuate the A/C system. For additional information, refer to the manufactures equipment instructions.
Check the A/C system for a sufficient vacuum. For additional information, refer to the manufactures equipment instructions.
Charge the A/C system with refrigerant.
Check the A/C system for correct operation.

Trace the compressor lines back to locate the high and low side fittings, you only recharge from the high side !

A new replacement A/C compressor contains 150 ml (5 oz.) refrigerant oil. If the amount of oil drained from the removed A/C compressor is between 90 and 150 ml (3 to 5 oz.), pour the same amount plus 28 ml (1 oz.) of clean oil into the new A/C compressor. If the amount of oil drained from the old A/C compressor is greater than 150 ml (5oz.), pour only 150 ml (5 oz.) of clean refrigerant oil into the new A/C compressor. If the amount of refrigerant oil drained from the old A/C compressor is less than 90 ml (3 oz.), pour 90 ml (3 oz.) of clean refrigerant oil into the new compressor.
When replacing components of the air conditioning refrigerant system, add oil to the replacement components.

5oz of oil are contained in the new compressor. The air conditioning system requires a total of 7oz of oil.
