Maintenance • frequent low-speed operation, consistent heavy traffic less than 25 mph (40 km/h) • operating in severe dust conditions • operating the vehicle off road • towing a trailer over 1,000 miles (1,600 km) • sustained, high-speed driving at Gross Vehicle Weight Rating (maximum loaded weight for vehicle operation) • 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 the engine coolant The concentration, additive strength and level of coolant should be checked at the mileage intervals listed in the scheduled maintenance information. Be sure to read and understand Precautions when servicing your vehicle in your Owner's Manual. When the engine is cold, check the level of coolant in the reservoirs. See Under Hood Overview for the location of the engine and secondary cooling system reservoirs. 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. Note: The engine coolant should be between the MIN and MAX marks (within the COLD FILL RANGE), as listed on the engine coolant reservoirs. Note: Coolant expands when it is hot. The level may extend beyond the MAX mark. If the level is below the MIN mark, add engine coolant immediately see Adding coolant in this chapter. Note: For best results, coolant concentration should be tested with a refractometer such as Rotunda tool 300- ROB75240 available from your dealer. Ford does not recommend the use of hydrometers or coolant test strips for measuring coolant concentrations. The coolant concentration should be maintained within 48% to 50%, which equates to a freeze point between -30 °F and -34 °F. Note: Automotive fluids are not interchangeable; do not use engine coolant/antifreeze or windshield washer fluid outside of its specified function and vehicle location. 52 2013 Diesel (67l) Supplement, 1st Printing USA (fus)

ENGINE AND SECONDARY COOLING SYSTEM COOLANT
Checking the engine coolant
The concentration, additive strength and level of coolant should be
checked at the mileage intervals listed in the
scheduled maintenance
information.
Be sure to read and understand
Precautions when
servicing your vehicle
in your
Owner’s Manual.
When the engine is cold, check the level of coolant in the reservoirs. See
Under Hood Overview
for the location of the engine and secondary
cooling system reservoirs. 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.
Note:
The engine coolant should be between the MIN and MAX marks
(within the COLD FILL RANGE), as listed on the engine coolant reservoirs.
Note:
Coolant expands when it is hot. The level may extend beyond the
MAX mark.
If the level is below the MIN mark, add engine coolant immediately see
Adding coolant
in this chapter.
Note:
For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300– ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30 °F and -34 °F.
Note:
Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
