1. Insufficient coolant in the cooling system or dirt/scales
having accumulated inside the cooling water passages
especially in the radiator core.
2. Choking or damage of radiator passages.
3. Defective thermostat.
4. Non operation of electrically operated fan. (40 Amp. fuse
blown)
5. Coolant leakage.
6. Auxiliary tank cap not sealing properly.
7. A.C. condenser fan not working.
8. Excessive refrigerant charging in the A.C. system.
9. Improper bleeding of the cooling system.
Prevention of Rust Formation :
To prevent rust formation, use the branded premixed engine
coolant in the radiator.
This is sufficient to operate the car upto -40
0
C.
Fuel Sedimenter (CR-4): (if fitted)
The water accumulated should be drained if the water in
fuel sedimenter lndicator in the cluster glows during engine
running.
Fuel sedimenter (If fitted) is the equipment fitted in fuel
system to separate Water contents from diesel and to
prevent the water from entering the Fuel System.
CAUTION
Water ingress in fuel system can result in system failure.
A water sensor is fitted in the sedimenter to indicate to
the driver that the sedimenter has to be drained. Check
if water in fuel sedimenter indicator lamp in instrument
cluster is ‘ON’ (if fitted).
NOTICE
If the water in fuel indicator comes ON, immediately take
the vehicle to an Authorised service station.
Limp - home mode operation :
When water gets accumulated in water
sedimenter, “water in fuel indicator lamp”
on instrument cluster remains ON
continuously.
