Recommended Antifreeze Agents
The specification for low silicate antifreeze which
meets ASTM 4985 test (GM6038M spec) criteria.
Note :
1. Engine is supplied with Premix Coolant as
First Fill.
2. Mixing of other brands with
Antifreeze
Coolant is not recommended.
Before adding the antifreeze agent into the
cooling system.
i.Inspect the cooling system for leakages and
clean it thoroughly.
Certain precautions have to be taken to enable
the cooling system to function properly at very low
ambient temperatures. To attain the recommended
working temperature of the engine faster, it is
necessary to use a radiator blind.
In view of the grave risk of damage due to frost,
the cooling system of the engine should be filled
with recommended quantity of antifreezing agent.
Percentage of antifreeze agent in cooling system
which depends upon ambient temperature is shown
in following table :

Before adding the antifreeze agent into the
cooling system.
i.Inspect the cooling system for leakages and
clean it thoroughly.
ii.Inspect the thermostat and replace if found
defective.
It is advisable to attach a warning sign to
the radiator neck reading.
"Antifreeze Solution is effective upto -
40
0
C. Do not drain off cooling system'
It is recommended that the entire cooling
system should be drained and filled with fresh
mixture of antifreeze agent and water in the
ratio of 50:50 for ambient temperature of upto
-40
0
C Coolant should be drained and
replenished in the recommended ratio every
two years Or 2400 hrs. which ever is
earlier.
Electrical System
At low ambient temperatures particular care
should be taken for electrical system. Useful
instructions on this subject are given below.
A full state of charge in battery should be
maintained by carefully servicing and reduced
current consumption. Below ambient temperatures,
the starting capacity of a battery is seriously
affected.
The specific gravity of the electrolyte should
be raised from 1.21 to 1.28 when operating at
temperatures below -15
0
C. The battery should
be removed and stored in a warm place when not
in operation. While reconnecting the battery,
observe polarity and care should be taken to
check that the terminals are kept clean and free
from oxide. A run down battery should be
charged. Do not add distilled water to discharged
or cold battery.
