Engine Cooling System
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.

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.

Changing of Engine Oil and Oil Filter Changing of Engine Oil and Oil FilterChanging of Engine Oil and Oil Filter Changing of Engine Oil and Oil Filter
Changing of Engine Oil and Oil Filter
Change the oil and oil filter at specified service intervals. (Engine oil and
oil filter may be changed earlier inline with recommendation given for
additional maintenance schedule under severe driving condition)
Changing of oil and oil filter requires access from underneath the vehicle.
Vehicle should be raised on a hydraulic lift of a service station or should
be on a service pit.
1 . Run the engine until it reaches normal operating temperature. Then
shut it off.
2. Remove oil sump guard.
3. Open the bonnet and remove engine oil filler cap. Remove the drain
plug of the oil sump from the bottom of the engine. Drain the oil into
an appropriate container.
4. Remove the oil filter with the help of special wrench. The removed
oil filter should not be reused and hence should be destroyed to
avoid recycling of the same. Used filter and oil should be disposed
in compliance with the current legislation.
5. Ensure cooler is tightened to it’s position.
6. Smear a little fresh engine oil on rubber gasket of new engine oil
filter. Hand tighten the engine oil filter fully and further 3/4 turn with
special tool.
Do not over tighten engine oil filter as this may damage oil filter and
oil may leak out.
7. Before filling in fresh oil in the engine, clean the drain plug..

6. Refit the drain plug using a new sealing washer. Tighten
drain plug to 5 mkg. torque.
7. Fill, recommended quantity of fresh engine oil in the crank
case and secure the oil filler cap in its place.
8. Start the engine and run for a few minutes. The engine oil
pressure indicator lamp should go ‘off ’ after starting the
engine.
9. Check for engine oil leakages.
10. Stop the engine and recheck engine oil level after a few
minutes. If necessary add oil to bring the level to the upper
mark on the dipstick.
