NOTE
Maximum recommended ELC concen-
tration is 60%
ELC and 40% water by
volume (a 60/40 coolant mixture). The
minimum recommended concentration
is 40%.

Condition
Perform a visual inspection of the coolant.
It should have no cloudiness or floating
debris. Determine the chemical inhibitor
concentration level by using an extended
life coolant specific test kit or test strips.
Inhibitor concentration level determines
corrosion protection. If you are concerned
about possible coolant quality,
contamination, or mechanical problems,
submit a coolant sample for analysis.
Improper maintenance may cause coolant
degradation and could result in damage to
the cooling system and engine
components. Consult your dealer or
the coolant manufacturer’
s representative
for recommended extended life coolant test
kits, test strips, and laboratory sample
procedures.
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 Coolant
Level on page 30. When adding coolant,
avoid mixing different brands and
formulations. If the coolant is mixed with
more than 25% of a different formulation,
engine 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.
Coolant Filter
Y
our engine is equipped with a coolant
filter designed to capture and remove
harmful deposits from the cooling system
to help prolong system life. It is a "blank
filter" and does not contain chemicals or
time-release additives. Replace it only with
a blank filter at the interval specified in the
Preventative Maintenance Schedule.
Never use filters that contain supplemental
coolant additives (SCAs) in an ELC-filled
system.
CAUTION
Use of non-genuine coolant filters can
cause severe engine damage.
