Oil Charge Additions


Compressor oil level should be checked whenever the A/C system is discharged for repair or due to a malfunction. To ensure proper oil level after system service, proceed as follows:
1. Discharge system and repair as needed. If compressor is replaced, ensure that oil level in replacement compressor is the same as the oil level in the defective compressor. If the evaporator or condenser is replaced, add 1 ounce of oil to each component prior to installation.
2. Evacuate and recharge system, then operate A/C until pressure gauge readings stabilize (approximately 10 minutes).
3. Stop engine and perform "Oil Level Check."
