Engine Coolant Change
WARNING:
To help avoid danger of being burned, do not remove degas-
sing tank cap while engine and radiator are still hot. Scald-
ing fluid and steam can be blown out under pressure if cap
is taken off too soon.
CAUTION:
When changing engine coolant, use mixture of 50% water
and 50% ethylene-glycol base coolant (Anti-freeze/Anti-
corrosion coolant) for the market where ambient tempera-
ture falls lower than – 16_C (3_F) in winter and mixture of
70% water and 30% ethylene-glycol base coolant for the
market where ambient temperature doesn't fall lower than
–16_C (3_F).
Even in a market where no freezing temperature is antici-
pated, mixture of 70% water and 30% ethylene-glycol base
coolant should be used for the purpose of corrosion protec-
tion and lubrication.
1) Remove degassing tank cap when engine is cool.
2) Loosen radiator drain plug (1) to drain coolant.
3) Tighten drain plug securely.
4) Fill cooling system with specified coolant through degassing
tank filler inlet, up to "FULL" level mark (2) on degassing tank (1).
5) Loosen bleed screw on thermostat cap to bleed air and tighten
it after confirmation of overflow.
6) Run engine with replenishing coolant, until radiator upper hose
is hot.
7) Add coolant as necessary until coolant reaches "FULL" level
mark on degassing tank.
Reinstall degassing tank cap (3).
