Cooling System
The cooling system of your new vehicle is filled at the factory
with either a Type II Fully-Formulated Coolant (Purple), Type III
ELC - Extended Life Coolant (Red), or nitrite-free Shell Rotella®
Ultra ELC (YELLOW) coolant. The type of coolant depends upon
the engine manufacturer and the preference of the purchaser, if
optional coolants are allowed.
The Type II coolant must meet International® Type ll
specifications, such as the Fleetrite® Premium 50/50 with
SCA (P/N: ZJJSCA5550). The Type III coolant must meet
International® Type IlI specifications such as the Shell Rotella®
ELC - Extended Life Coolant (P/N 94042). Refer to the label
on the deaeration tank to determine the coolant type. If no
label is present, use Type II Fully-Formulated Coolant (Purple)
and maintain the Supplemental Coolant Additives (SCA’s)
accordingly. Consult the Engine Operation and Maintenance
Manual for coolant service life details.

To prevent personal injury or death from
hot coolant or steam use only the following
procedure to remove the pressure cap from
the deaeration tank. Allow the engine to cool
first. Wrap a thick, heavy cloth around the
cap. Depending on the type of cap, push down,
loosen cap slowly to its first notch position, or
unscrew cap slowly; then pause a moment to
allow pressure to release through the overflow
tube. After the pressure has been released, the
pressure cap may be removed.
WARNING
Do not exceed the pressure rating on the
deaeration tank. Ensure that the pressure rating
of the deaeration tank cap matches that listed
on the side of the tank, or the tank may burst,
causing property damage, personal injury, or
death.
