•
Engine Coolant Level –
Check/Correct:
With the engine off and
temperature cool:
°
Check coolant level. It should
be visible through the clear
plastic surge tank.
°
Add coolant as necessary by
removing the pressure cap on
the neck of the surge tank or
sight glass.
°
Replacement or top up
coolant should have the same
antifreeze concentration and
corrosion inhibitor content
as the original coolant in the
cooling system.
°
Always dilute antifreeze to
the correct concentration
based on freeze protection
before adding it to the cooling
system. Adding or using 100%
antifreeze in a cooling system
may result in cooling system
plugging and overheating
problems.
•

NOTE
It is recommended to top up DEF
when refueling.
See Engine Af-
tertreatment Systems Operator’s
Manual for DEF information.
