Precautions for removal work

q

If the coolant contains antifreeze, dispose of it correctly as chemicals.

q

After disconnecting hoses or tubes, cover them or fit plugs to prevent dirt or dust from entering.

q

When draining oil, prepare a container of adequate size to catch the oil.

q

Check the match marks showing the installation position, and put match marks in the necessary places
before removal to prevent any mistake when assembling.

q

To prevent any excessive force from being applied to the wiring, always hold the connectors when dis-
connecting the connectors. Do not pull the wires.

q

Attach the tags to wires and hoses to show their installation position to prevent any mistake when in-
stalling.

q

Check the number and thickness of the shims, and keep them in a safe place.

q

When slinging component, be sure to use lifting equipment of ample strength.

q

When using forcing screws to remove any component, tighten the forcing screws uniformly and alter-
nately.

q

Before removing any unit, clean the surrounding area and fit a cover to prevent any dust or dirt from
entering after removal.
