Compressor HVAC: Service Precautions
PRECAUTIONS
Precaution for Service of Compressor
-
Plug all openings to prevent moisture and foreign matter from entering.
-
When the compressor is removed, store it in the same position as it is when mounted on the car.
-
When replacing or repairing compressor, follow "Maintenance of Oil Quantity in Compressor" exactly. See: Service and
Repair/Procedures.
-
Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with oil, wipe it off by using a clean waste cloth
moistened with thinner.
-
After compressor service operation, turn the compressor shaft by hand more than 5 turns in both directions. This will equally distribute
oil inside the compressor. After the compressor is installed, let the engine idle and operate the compressor for 1 hour.
-
After replacing the compressor magnet clutch, apply voltage to the new one and check for normal operation. [Gap between clutch disc
and pulley is 0.3 - 0.6 mm (0.012 - 0.024 in)]
