MAINTENANCE SPECIFICATIONS
Topping Up the Engine Oil
1.
If checking the engine oil just
after stopping the engine, wait 15
minutes for the oil to drain back
into the oil pan before checking
the fluid level.
2.
Top up with oil, if necessary, via
the filler opening. Use the correct
grade in the correct quantity.
3.
After topping up, wait one minute
and check the oil level again.
4.
Reinstall the oil fill cap and twist
to lock it in place.

dations and Specifications” on
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 may be equipped with
an optional 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.
