Important!
Do not loosen or open the radiator cap when coolant is hot.
Doing so may cause hot water or steam to splash out, resulting
in burn. When opening the radiator cap, be sure to confirm the
coolant is cold. Cover a thick cloth over the cap and loosen it
slowly to reduce pressure, then open the cap.
6.
Close the radiator cap firmly and run the engine at
approx. 2000 rpm. In addition, set the heater temperature
adjuster to the max position to circulate coolant in the
heater conduit system.
7.
Confirm that the temperature gauge reads half or more of
full scale and that the thermostat is activated.
Then continue idling 5 minutes more and switch off the
engine, and allow it to cool.
8.
After the engine cools down, check the coolant level and
refill it if necessary. When the level is lowered extremely,
check the coolant conduit system and reservoir hose for
leak.
9.
Pour coolant into the reservoir to MAX level.
Refill Coolant
Important!
After closing the cooling system, let engine run warm until
