Mazda 6 Service Manual: Service cautions
HANDLING INSUFFICIENT REFRIGERANT LEVEL
- If an insufficient refrigerant level is detected at troubleshooting,
do not charge (add) the refrigerant. Because an accurate amount of
refrigerant cannot be determined from the pressure indicated on the manifold
gauge, never charge the refrigerant. If there is too much or too little
refrigerant from the refilling, there may be secondary problems such as
damage to the refrigerant cycle parts, or a decrease of cooling performance.
Therefore, if it is determined that the refrigerant level is insufficient,
completely remove refrigerant from the refrigerant cycle and refill with
refrigerant to the specified amount.
HANDLING COMPRESSOR OIL
- Use only ATMOS GU10 compressor oil for this vehicle. Using a PAG oil
other than ATMOS GU10 compressor oil can damage the A/C compressor.
- Do not spill ATMOS GU10 compressor oil on the vehicle. A drop of
compressor oil on the vehicle surface can eat away at the paint. If oil gets
on the vehicle, wipe it off immediately.
- ATMOS GU10 compressor oil (PAG oil) has a higher moisture absorption
efficiency than the previously used mineral oil. If moisture mixes with the
compressor oil, the refrigerant system could be damaged. Therefore, install
caps immediately after using the compressor oil or removing refrigerant
system parts to prevent moisture absorption.
