A/C COMPRESSOR MAINTENANCE FOR STORED VEHICLES
When a vehicle is stored for a long period, the volume of oil in the A/C compressor may decrease due to oil flow into the condenser, pipes, etc..
If the A/C system is turned on at high engine RPM after a long storage period, A/C compressor damage may result.
To minimize the possibility of damage to the A/C compressor while storing a vehicle, perform the following recommended procedure at least once a
month to lubricate the compressor.
