CLEANING OF COOLING SYSTEM
Wait until the temperature falls below 50°C before
draining.
Draining procedure
Drain the cooling system. Use a drain pan with a
capacity of 20 litres.
Prolonged and repeated contact with used
antifreeze can cause skin disorders or other
body injury.
System flushing & filling
Mix 0.5 kg of sodium carbonate with water for
preparing flushing mixture.
Fill the system slowly.
Wait 2 or 3 minutes to allow air to be vented and
add mixture to bring the level to the top.
Do not install the radiator cap.
Operating procedure
Operate the engine for 5 mins. with the flushing
mixture temperature above 80°C.
Shut the engine off and drain the cooling system.

RECOMMENDATIONS
Quality of Lubricating oil is one of the key drive
factors to decide the performance, durability and
total cost of operation of diesel engine. Hence we
have always been recommending the best available/
suitable engine oil to be used in our engine.
Cummins strongly recommends the use of
SAE 15W40 lub oil with API, CF4 classification
for all Cummins engines to get the various
advantages and optimum performance from
the engine.
This oil should have a minimum TBN of 10.5.
NOTE
Above limits are for reference only and exact
applicable values can be obtained from the
respective oil manufacturer against specific
brand of oil.
The responsibility of meeting oil quality lies
with the oil manufacturer and Cummins will
not be responsible for problems occurring on
engines due to poor quality of oil.
If in doubt about the lub oil quality, contact
lub oil manufacturing company and get the oil
analysed in laboratories.
CAUTIONS
Beware of spurious oils in the market. Bad
quality of lubricating oil is detrimental to
engine performances. Hence, oil should
always be procured from the original
manufacturer or the authorized distributors.
Lubricating oil to be used on the engine must
meet all the qualities as per manufacturer’s
specifications. Cummins recommends audit
checks of fresh engine oil to ensure the
quality of oil. Facility to check suitability of oil
for using it in the engine is available with
Cummins Service Network.
Do not intermix different brands of oil since
two different brands may not be compatible
with each other. It is therefore recommended
that the brand which is used for initial fill,
should only be used for top-up.
However, in case of non-availability of specific
brand, different brand of oil may be used at
the time of oil change. In that case, drain all
the existing oil and flush the lub oil system
with new brand oil and then charge the
system with new brand oil.
COOLANT RECOMMENDATIONS
Cummins recommends, use of Premix Coolant, for
engine cooling. This is ‘Ready to Use’ type Coolant &
is available
