Maintenance and Specifications • use of fuels with sulfur content other than ultra-low sulfur diesel (ULSD) • use of high-sulfur diesel fuel ENGINE AND SECONDARY COOLING SYSTEM COOLANT Checking engine coolant The concentration (freeze point protection), additive strength (corrosion inhibitor), and level of coolant should be checked at the mileage intervals listed in the scheduled maintenance information. The coolant concentration should be maintained at 50/50 coolant and water, which equates to a freeze point of -36°C (-34°F). Coolant concentration testing is possible with a hydrometer or antifreeze tester (such as the Rotunda Battery and Antifreeze Tester, 0014-R1060). The level of coolant should be maintained within the COLD FILL RANGE in the coolant reservoirs. If the level falls below, add coolant per the instructions in the Adding coolant section. Your vehicle was factory-filled with a 50/50 coolant and water concentration. If the concentration of coolant falls below 40% or above 60%, the engine parts could become damaged or not work properly. A 50/50 mixture of coolant and water provides the following: • freeze protection down to -36°C (-34°F). • boiling protection up to 129°C (265°F). • protection against rust and other forms of corrosion. • an accurate temperature readout from the engine coolant gauge. When the engine is cold, check the level of coolant in the reservoirs. See Identifying components in the engine compartment for the location of the engine and secondary cooling system reservoirs. • The coolant should be within the COLD FILL RANGE in the coolant reservoirs. • Refer to the scheduled maintenance information for service interval schedules. • Be sure to read and understand Precautions when servicing your vehicle in your Owner's Guide. If the coolant has not been checked at the recommended interval, the engine or secondary coolant reservoir may become low or empty. If either reservoir is low or empty, add coolant to the reservoir(s).

ENGINE AND SECONDARY COOLING SYSTEM COOLANT
Checking engine coolant
The concentration (freeze point protection), additive strength (corrosion
inhibitor), and level of coolant should be checked at the mileage intervals
listed in the
scheduled maintenance information.
The coolant
concentration should be maintained at 50/50 coolant and water, which
equates to a freeze point of -36°C (-34°F). Coolant concentration testing
is possible with a hydrometer or antifreeze tester (such as the Rotunda
Battery and Antifreeze Tester, 0014–R1060). The level of coolant should
be maintained within the COLD FILL RANGE in the coolant reservoirs. If
the level falls below, add coolant per the instructions in the
Adding
coolant
section.
Your vehicle was factory-filled with a 50/50 coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.
A
50/50 mixture of coolant and water provides the following:
•
freeze protection down to -36°C (-34°F).
•
boiling protection up to 129°C (265°F).
•
protection against rust and other forms of corrosion.
•
an accurate temperature readout from the engine coolant
gauge.
When the engine is cold, check the level of coolant in the reservoirs. See
Identifying components in the engine compartment
for the location of
the engine and secondary cooling system reservoirs.
•
The coolant should be within the COLD FILL RANGE in the coolant
reservoirs.
•
Refer to the
scheduled maintenance information
for service interval
schedules.
•
Be sure to read and understand
Precautions when servicing your
vehicle
in your
Owner’s Guide.
If the coolant has not been checked at the recommended interval, the
engine or secondary coolant reservoir may become low or empty. If
either reservoir is low or empty, add coolant to the reservoir(s). Refer to
Engine and secondary cooling system refill procedure
in this chapter.
