Coolant Extender
Add extended life coolant extender, if
necessary, according to the corrosion
inhibitor concentration required. DO NOT
add coolant extender to nitrite-free coolant.
Checking Coolant Level
Check the coolant level daily. See
CAUTION
When adding coolant, avoid mixing dif-
ferent brands and formulations. If the
coolant is mixed with more than 25%
of a different formulation (for example,
mixing OAT and NOAT coolants), en-
gine corrosion damage could occur. If
mixing exceeds 25% of total system
volume, it is recommended to flush
and refill the system completely with
one type of coolant.
Cooling System Sealing Additives
and Soluble Oils
OK
1
1.
Do not use soluble oils or sealing
additives.
CAUTION
The use of sealing additives or soluble
oils in the cooling system can cause
damage to the engine. These additives
can plug various areas of the radiator,
EGR system and oil cooler. The plug-
ging of the cooling system can hamper
heat transfer, causing internal engine
damage. DO NOT use sealing addi-
tives or soluble oils in the cooling sys-
tem. The use of sealing additives can
•
Build up in coolant low-flow
areas
•
Plug the radiator and oil cooler
•
Damage the water pump seal
•
Damage heat transfer surfaces
•
Damage seals and hoses
•
Corrode brass and copper
Failure to comply may result in equip-
ment or property damage.
