INSPECTION

1.

CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR

The engine coolant level should be between the ”LOW” and ”FULL” lines, when the engine is cold.
If low, check for leaks and add engine coolant up to the ”FULL” line.
2.

CHECK ENGINE COOLANT QUALITY

(a)

Remove the radiator cap from the water outlet.

CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b)

There should not be any excessive deposits of rust or scale around the radiator cap or water outlet
filler hole, and the coolant should be free from oil.

If excessively dirty, clean the coolant passages and replace the coolant.
(c)

Reinstall the radiator cap.
