7. Inspecting and changing the
cooling water
Danger
●
Do not open the radiator cap while the engine
is running or immediately after the engine
stops. Stop the engine and wait until the
engine has cooled down before opening the
cap. Otherwise, hot water gushes out and you
may be burnt.
Inspection
Open the bonnet and check if the water level in
the reserve tank is between the upper and
lower limits. If the water level is too low, supply
antifreeze from the water filler port of the
reserve tank.
Replacement
(1) Remove the radiator cap, loosen the drain
plug and drain the water in the radiator
completely.
(2) Loosen the drain cock on the right side of
the engine and drain the water in the
engine.
(3) Wash the radiator inside in city water until
no dust or rust comes out.
* By supplying water mixed with radiator
detergent, idling the engine for more than
15 minutes and discharging the water, the
radiator inside can be more completely
cleaned.
(4) Tighten the drain plug, supply antifreeze to
the specified level, and add fresh water until
overflowing.
(5) Install the radiator cap, start the engine to
mix the antifreeze and fresh water.
<Handling of antifreeze>
Antifreeze acts to decrease the water freezing
temperature. Depending on the mixture ratio of
antifreeze, the freezing temperature varies. In
cold districts, select a safety density referring to
the table below. The antifreeze at the time of
factory shipment is based on the external
atmospheric temperature of –30
℃
.
