27. Dispose of all fluids according to local regulations and mandates.
Note: Cleanliness is an important factor. Before the removal procedure, the exterior of the
component should be thoroughly cleaned. This will help to prevent dirt from entering the internal
mechanism.
Note: Put identification marks on all lines, on all hoses, on all wires, and on all tubes for
installation purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this
helps to keep contaminants from entering the system.
