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 ELCt
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 ELC test kits, test strips,
and laboratory sample procedures.
Coolant Extender
Add ELC 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. 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 can 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
Your engine may be equipped with a
coolant filter. 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 your engine's
operator's manual. Never use filters that
contain supplemental coolant additives
(SCAs) in an ELC-filled system. Consult
your engine operator's manual for
information on the coolant filter and service
procedures.
CAUTION
Use of non-genuine PACCAR coolant
filters can cause severe engine dam-
age.
