Coolant Recommendations
and Specifications
The cooling system in your vehicle
was factory filled with Extended Life
Coolant (ELC) that meets or exceeds
all ASTM D 6210 requirements.
PACCAR recommends only using a
50/50 mixture of distilled water and
ELC when cooling system service
is required. A 50/50 mixture of ELC
and distilled water will provide freeze
protection down to -34°F (- 36.7°C),
which is adequate for most locations
in North America. For extremely cold
operating conditions, a 60/40 mixture
(coolant/water ratio) can be used to
provide freeze protection down to
-62°F (-52.2°C).
Your engine is also equipped with a
Coolant Filter designed to capture
and remove harmful deposits from the
cooling system to help prolong system
life.
Checking Coolant Condition
To ensure the Extended Life Coolant
(ELC) in your vehicle always provides
maximum freeze protection, perform
the following tests:
1. Check the coolant color at every
maintenance interval. It should be
a bright red with no signs of debris
or any oil.
2. Test the freeze point at least two
times a year. A refractometer or
test strips can be used to measure
the protection level.
3. Keep the cooling system at full
levels by topping-up using ELC
pre-diluted to 50/50 blend.
