To prevent rush formation and freezing of water
inside water jackets of crankcase and cylinder
head mix antifreezing agent as recommended.
Percentage of antifreeze agent in cooling system
which depends upon ambient temperature is
shown in following table :
Up to Ambient Heavy Duty Antifreeze

Recommended Antifreeze Agents
Volvoline
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 up to -40 C. Coolant
should be drained and replenished in the
recommended ratio every two years Or 1500 hrs
which ever is earlier.
LUBRICANTS
Please use only recommended brands of oil for
getting optimum engine performance and life.
There are several brands of lubricating oils in the
market. Only some of these oils have been
approved by us for use in S-3.8-G engine. The
lubricating oils approved by us is volvoline which
conform to following specification :
SAE API CF4 Engine Oils
The recommended oils have certain vital properties
that help to reduce the wear and tear of the
components. We have tested these oils for
thousands of hours in similar conditions your
equipments is likely to encounter. The optimum
period of use for each oil filling has been carefully
determined. Therefore, always use only the
approved oil. Strictly adhere to the engine oil and
oil filter cartridge change period specified by us. The
engine oil should be replace by at every 500 hrs
along with the engine oil filter cartridge and "O' ring.
The oils of two different specification should not
be mixed.
Do not use recycled oils even for topping up.
They have already lost their vital properties. The
adverse effect using reclaimed oil will not be seen
immediately, but the life of the components will
be greatly reduced.
It is difficult to recognise a poor quality oil.
Therefore, buy the recommended brands in sealed
tins only from authorised dealers.
The oil change periods recommended in
maintenance schedule should be adhered to.
Recommended grades of engine oils confirming to
SAE API CF4 and MB 228.1 specifications and
grade selected according to range of ambient
temperatures are to be as given below :
Coolant
Coolant reservoir is to be filled externally, upto ‘L’ level
with same coolant concentration.
Coolant is recommended to prevent corrosion of
engine & radiator and to increase boiling point of
water. An ethylene glycol (type JIS K 2234-94,
class 2)
During initial fill of coolant in the engine 5 liter
ethylene glycol is to be mixed with 5 liter of soft
water. And the mixture is to be poured in the
radiator. Please note that colour of the ethylene
glycol supplied along with engine is green.
50:50 water to ethylene glycol mixture is to be
used for top up.
Change Coolant during every D Check.
