Inspect and Clean Radiator Fins and Oil Cooler Fins

Be sure to put on protective goggles when handling
compressed air or high-pressure water in
inspection of the engine. Otherwise, your eyes
may be hurt by dust, scattered matters,
compressed air, high-pressure water or steam.

1. Blow out dust with compressed air (at 0.2 MPa or less)

from the fins.

Be careful not to damage the fins with compressed air.

2. Clean the fins with neutral detergent and city water if a

lot of dust adheres to the fins.

Use high-pressure water and compressed air at as
low pressure (0.2 MPa) as possible. Do not use a
wire brush to clean the fins. A wire brush may
damage the fins.
