COOLANT CHECK
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR
RESERVOIR
The engine coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add engine coolant up to the
ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
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 radiator filler hole, and the coolant
should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap. EG±330

COOLANT REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
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) Loosen the 2 drain plugs (for the engine and radiator), and
drain the coolant.
(c) Close the drain plugs.

2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
wUse a good brand of ethylene±glycol base coolant and
mix it according to the manufacturer's directions.
wUsing coolant which includes more than 50 %
ethylene±glycol (but not more than 70 %) is
recommended.
NOTICE:
wDo not use an alcohol type coolant.
wThe coolant should be mixed with demineralized water or
distilled water.
