4. Initial coolant filling through pressure cap
opening.
Opening EGR hose and top hose of heater
core.
Filling coolant through pressure cap
opening till coolant is visible in the EGR
hose. Refit EGR hose.
Keep filling coolant till coolant is visible in
the heater hose. Refit the heater hose.
Fill the no loss tank till the max level.
5. Start the engine and maintain engine 3000
rpm.
Close the pressure cap & start the engine
in idle condition for a few seconds. Rev up
& maintain engine speed at 3000±100 rpm.
Radiator fan switch ‘ON’ for the first time
once coolant temperature reaches the fan
trigger threshold.
Continue the de-aeration process until
completion of two heat cool cycles of
radiator fan (i.e. Radiator fan turns ‘ON’ &
‘OFF’ for two times).
Allow engine to cool down until coolant
temperature reaches ambient temperature.
6. Fill coolant after vehicle cool down.
After cool down, observe drop in coolant
level in no loss tank & if required fill coolant
until max mark.
Also open pressure cap & fill coolant till the
neck is full if required.
De-aeration process is now complete.
7. Step to be follow during de-aeration process
