CAUTION: Do not use metal tools to remove the O-ring seals. They can cause axial scratches across the O-ring seal grooves resulting in refrigerant leaks.
CAUTION: Do not use a screwdriver or similar tool to remove the A/C tube lock coupling spring; this can cause axial scratches across the O-ring seal grooves resulting in refrigerant leaks.
CAUTION: Maintain low speed drill rotation when inserting or removing the cleaning tool to prevent axial scratches which may cause future leaks.
CAUTION: Use only new green O-ring seals. The use of any O-ring seals other than specified may result in intermittent leakage during vehicle operation.
