For more information refer to the Cummins manual.

Routine Maintenance Recommendations:

1. Check the SCA concentration level every 15,000 miles/6 months.
2. Change the coolant filter every 15,000 miles/6 months.
3. Drain and flush the system every 240,000 miles/2 years, and
refill with a heavy-duty coolant (50/50 mix of water and
antifreeze).
4. Always use antifreeze. In addition to freeze protection, antifreeze
is essential for overheat and corrosion protection.
5. The supplemental coolant additive (SCA) is required.
6. Freeze point should be measured every 15,000 miles/6 months.
Fully formulated products contain SCA and are
required to protect the cooling system from fouling,
solder blooming and general corrosion. The cooling
filter is required to protect the coolant system from
abrasive materials, debris and precipitated coolant
additives.
Supplement coolant additives, or equivalent, are
used to prevent cylinder liner pitting, corrosion and
scale deposits in the cooling system. Use the correct
Fleetguard coolant filter to maintain the recommended
SCA concentration in the system by changing the
service filter at each oil drain interval.
NOTE: The correct filter is determined
by the total cooling system capacity and
oil drain interval. Refer to the Coolant
Capacity Specifications in this section.
CAUTION: Insufficient concentration of
the coolant additives will result in
cylinder liner pitting and engine failure.
The SCA concentration must not fall
below 1.2 units or exceed 3 units per
gallon of cooling system capacity.
