Do not remove radiator cap when engine is hot. It may spray hot
coolant on you causing serious injuries.
1. Ensure engine and radiator are cool.
2. Turn the radiator cap anti clockwise (without pressing it) until it
stops. This will relieve the pressure, if any in the cooling system.
3. Remove the radiator cap by pushing down and turning anti
clockwise.
4. The level of coolant should be upto the base of the filler neck.
Coolant should be added if it is low.
5. Secure the radiator cap in its place.
6. Add coolant into the auxiliary tank up to the high mark.
7. Put the cap back, on the auxiliary tank.

Topping of the coolant should be done in the auxiliary tank only.
Radiator cap should not be removed, if coolant is present in the
auxiliary tank.

If engine overheating occurs, there could be a fault in the
cooling system which may be on account of :
1. Less coolant in the cooling system or dirt/scale having
accumulated inside cooling water passages especially
in the radiator core.
2 . Choking of radiator passages due to foreign material or
damages.
3. Defective thermostat.
4. Defective coolant temperature sensor.
5 . Non operation of electrically operated fans (Controlled
by ECU).
6. Coolant leakage.
7. Radiator cap not sealing properly.
8 . A.C. condenser fan not working
9. Excessive refrigerant charging in the A.C. system.
10. No communication between auxiliary tank and radiator.

To prevent rust formation in the radiator use premixed
recommended anti-freeze coolant. This is sufficient to
operate the vehicle upto -40
oC.

The coolant refilling in the system is recommended to be
carried out through air evacuation and coolant filling method
for quick filling.
1 . Allow the engine to cool up to ambient temperature.
2 . Keep cabin heater valve (if applicable) at “ON” position
throughout the coolant refilling.

3. The complete cooling system should be drained (old coolant)
before refilling the system.
a. Remove radiator pressure cap
b. Drain the coolant from engine through the drain hole on
thermostat housing lower part. Drain coolant from radiator
through the radiator drain hole.
c. Refit the drain plugs on thermostat housing lower part and
the radiator.
d. Pour fresh water through the filler neck up to top and again
drain the water through the drain holes. This will ensure
removal of the old coolant from the system
e. After flushing out water, secure the drain plugs on radiator
and thermostat housing lower part properly with new
sealing washer.
f. Drain the auxiliary tank and refit the hoses.
4. Take the recommended coolant and water in 1:1 proportion
5. Carry out air evacuation and coolant filling on machine
( Vacuum filling)
( The machine setting to be done as follows,
Quantity to be filled: 6.1 lit approx, back pressure: 1.7 bar)
6. Fill the coolant in auxiliary tank up to “FIRST FILL / REFILL”
mark.
Manual Coolant refilling : Manual Coolant refilling :Manual Coolant refilling : Manual Coolant refilling :
Manual Coolant refilling :
If the air evacuation and coolant filling (vacuum filling) system is
not available, then alternate procedure is as mentioned below.1. Follow sr. no 1 to 4 indicated in Air evacuation and coolant
filling ( Vacuum filling) procedure.
2. Refill the coolant (coolant and water as per recommendation)
through radiator filler neck.
3. When coolant level comes up to radiator filler neck, wait and
allow air bubbles to escape from the system for 2 to 5 min.
Top up coolant in radiator filler neck when level drops.
4. Fill the coolant in the auxiliary tank up to “FIRST FILL / REFILL”
mark.
5. Start the engine and run at idle for 10 min. with open radiator
filler neck. Allow air to escape from the system.Top up coolant
slowly in the radiator filler neck while idling.
6. Stop the engine and allow air bubbles to escape from the
system. Top up coolant through radiator filler neck. Secure
the radiator pressure cap on radiator filler neck.
7. Start the engine and run in stationary condition at 2200 to
2500 rpm till thermostat opens and continue to run for 5
minutes. ( The radiator fans coming on is the indication of
opening the thermostat)
8. Stop the engine and allow it to cool. Open the radiator
pressure cap & top up coolant in radiator filler neck. Secure
the radiator pressure cap on the radiator filler neck.
9. Refill the coolant in the auxiliary tank till “first fill / Refill” level
mark.
10. The coolant refilling is complete now.
11. Ensure that there are no leakages in the completesystem.
