Ensure that the engine is stopped. Ensure that the
battery disconnect switch is in the OFF position.

The clearance between the cover (2) and the fan (1)
will require checking. The gap between the edge of
the cover and the tip of the fan blade (A) must be
checked in four equally spaced positions. The fan
blade should be as central as possible in the cover.
The minimum fan tip clearance is 2 mm
(0.07874 inch). If it is not possible to achieve the
minimum fan tip clearance, inspect the radiator
mounts. Refer to this Operation and Maintenance
Manual, "Engine Mounts - Inspect" for further
information.

Adjusting, "Cleanliness of Fuel System
Components" for detailed information on the
