Coolant Replenishment
Replenish the cooling system with coolant.
When radiator is emptied (for coolant change, etc.):
After filling with coolant up to the inlet port level, put the
radiator cap on and idle the engine for 5 to 6 consecutive
minute. Then remove the radiator cap and check and see
the coolant level. If the coolant is short, add to the radiator
as well as to the reserve tank.
If the reserve tank coolant level is lower than MIN,
replenish coolant to the reserve tank only.
In case there is no coolant in the reserve tank, make sure
of a drop in coolant temperature and add coolant through
the radiator inlet port. Then remove the cap and check the
coolant level after idling the engine for 5 to 6 consecutive
minutes.
Then add coolant into reserve tank fill up to full level.
