Envoy 2WD V6-4.3L VIN W (1998)
Refrigerant: Description and Operation
Caution: Avoid breathing A/C Refrigerant-134a and lubricant vapor and mist. Exposure may irritate eyes, nose, and throat. To remove R-134a
from the A/C system, use service equipment certified to meet the requirements of SAE J2210 (R-134a recycling equipment). If accidental system
discharge occurs, ventilate the work area before resuming service. Additional health and safety information may be obtained from the
refrigerant and lubricant manufacturers.
Important:
-
Do not mix R-12 refrigerant and R-134a refrigerant, even in the smallest amounts. R12 and R-134a are incompatible with each other. If the
refrigerants are mixed, compressor failure is likely to occur.
-
Use only the specified lubricant (PAG) for the R-134a A/C system and R-134a components. If you use lubricants other than those specified,
compressor failure is likely to occur. Coat all the fittings and the O-ring seals with clean 525 viscosity refrigerant oil in order to provide a
leak-proof seal and in order to aid in assembly and disassembly.
-
Do not store or heat the refrigerant containers above 52°C (125 °F).
-
Do not heat a refrigerant container with an open flame. If the container must be warmed, place the bottom of the container in a pail of warm
water.
-
Do NOT intentionally do the following to the refrigerant containers:
-
Drop
-
Puncture
-
Incinerate
-
Refrigerant will displace oxygen. Work in well ventilated areas in order to prevent suffocation.
-
Do NOT introduce compressed air to any refrigerant container or refrigerant component. Contamination will occur.
-
If you must carry a container of DOT CFR Refrigerant-134a in a vehicle, do not carry the refrigerant in the passenger compartment.
All of the Refrigerant-134a disposable, blue containers are shipped with a heavy metal screw cap in order to protect the valve and the safety plug of the
container from damage. Replace the cap after each use of the container in order to continue the protection.
