1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug to drain coolant.
3) Remove reservoir tank, which is on the side of radiator, and drain.
4) Tighten plug securely. Also reinstall reservoir tank.
5) Fillup radiator with coolantand bleed air by removing air bleeder plugs while cool engine running.
CAUTION:
Failure to bleed air causes engine overheat.
NOTE: Connect proper hoses to air bleeder pipe and reservoir tank to prevent coolant from spilling out.
6) After bleeding airfrom bleederpipes, connect bleederplugs and clamp them securely.
7) Add coolant as necessary until coolant level reaches the filler throat of radiator. Reinstall radiator cap.
8) Add coolant to reservoir tank so that its level aligns with Full mark. Then, reinstall cap aligning arrow marks on the tank and cap.
NOTE: When installing reservoir tank cap, align arrow marks on the tank and cap.
CAUTION: When changing engine coolant, use mixture of 50% water and 50% ANTIFREEZE/ANTICORROSION COOLANT for the market where ambient temperature falls lower than-16C(3F) in winter, and mixture of 70% water and 30% ANTIFREEZE/ANTICORROSION COOLANT for the market where ambient temperature doesn't fall lower than-16℃(3F).
Even in a market where no freezing temperature is anticipated, mixture of 70% water and 30% ANTIFREEZE/AN-TICORROSION COOLANT should be used for the purpose of corrosion protection and lubrication.
