U7 Important operation (in case of 100% Engine
V Coolant change) procedure for filling with
Engine Coolant
• Fill
with Engine Coolant (EC) to the radiator
filler neck.
• Fill with EC to the "MAX" line on the reservoir.
• Start the engine with the radiator cap removed
and bring
to operating temperature by running
engine at
2,500-3,000 revolution per minute
for 30 minutes.
• By EC temperature gauge reading make sure
that the thermostat is open.
• If air bubbles come up to the radiator filler
neck, replenish with EC repeat until the EC
level does not drop any further. Install the
radiator cap and stop the engine.
• Replenish EC to the "MAX" line on the reser­
voir and leave as it is until the engine gets cool.
• After the engine gets cool, start the engine and
make sure there is no
water running noise
heard
from the heater core while the engine
runs
at 3000 revolution per minute.
• Should water running noise be heard, repeat
the same procedure from the beginning.
