Impala V6-3.4L VIN E (2000)
Refrigerant: Service and Repair
REFRIGERANT RECOVERY AND RECHARGING
TOOLS REQUIRED
^
J 39500-B A/C Refrigerant Recovery, Recycling and Recharging (ACR4) System
^
J 41810 Pure Guard 2
^
J 41810-100A Active Flow Control Valve
CAUTION:
^
Avoid breathing the A/C Refrigerant 134a (R-134a) and the lubricant vapor or the mist. Exposure may irritate the eyes, nose, and throat.
Work in a well ventilated area. In order to remove R-134a from the A/C system, use service equipment that is certified to meet the
requirements of SAE J 2210 (R-134a recycling equipment). If an accidental system discharge occurs, ventilate the work area before
continuing service. Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
^
For personal protection, goggles and gloves should be worn and a clean cloth wrapped around fittings, valves, and connections when
doing work that includes opening the refrigerant system. If R-134a comes in contact with any part of the body severe frostbite and
personal injury can result. The exposed area should be flushed immediately with cold water and prompt medical help should be obtained.
NOTE:
^
R-134a is the only approved refrigerant for use in this vehicle. The use of any other refrigerant may result in poor system performance or
component failure.
^
To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
^
Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity
mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
^
R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, as they are incompatible with each other. If the
refrigerants are mixed, compressor failure is likely to occur. Refer to the manufacturer instructions included with the service equipment before
servicing.
The J 39500-B removes the Refrigerant - 134a from the vehicle's A/C system. The recovery procedure uses one filtering cycle. The evacuation procedure
uses an automatic multiple pass filtering cycle. These filtering cycles ensure a constant supply of clean, dry refrigerant for the A/C system charging.

Refrigerant System Capacity
For the amount of Refrigerant - 134a needed for A/C system (recharging). Refer to System Capacities.
Refrigerant System Oil Charge Replenishing
If refrigerant oil was removed from the A/C system during the recovery process, add the same amount of refrigerant oil to the system in the recharging
process. The refrigerant oil must be replenished if the oil loss is due to component replacement or abrupt loss. Refer to Refrigerant Oil Distribution
Specifications.
