tor by a vacuum. Thus, the radiator is kept filled with coolant to the desired level
at all times, resulting in increased cooling efficiency. the coolant level should be
at or above the appropriate mark on the reservoir tank when the system is cold.
• Check the coolant level daily or when refueling.
• Drain and flush the coolant system every 60,000 miles or two years, and
refill with a heavy-duty coolant (50/50 mix of water and anti-freeze).
• If the coolant is below the MIN mark, the low coolant alarm will sound and
the low coolant light will appear on the dash. You will need to stop and
check for coolant loss, before driving.
• The coolant level to remain between the MAX and MIN level in the reser-
voir.
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/3 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 essen-
tial for overheat and corrosion protection.
5. The supplemental coolant additive (SCA) is requires with the ISM.
6. Freeze point should be measured every 15,000 mile/6 months
Fully formulated products contain SCA and are required to pro-
tect the cooling system from fouling, solder blooming and general
corrosion. The cooling filter is required to protect the coolant sys-
tem from abrasive materials, debris and precipitated coolant addi-
tives.
Supplement coolant additives, or equivalent, are used to prevent
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. Maintain the correct concentra-
tion 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
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.
Use the correct Fleetguard coolant filter to maintain the recommended SCA
concentration in the system. Maintain the correct concentration by changing the
