Maintenance and Specifications ENGINE AND SECONDARY COOLING SYSTEM COOLANT Checking engine coolant Note: For best results, coolant concentration should be tested with a refractometer such as Rotunda tool ROB75240 available from your dealer. Ford does not recommend the use of hydrometers or coolant test strips for measuring coolant concentrations. 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. Note: Automotive fluids are not interchangeable; do not use engine coolant/antifreeze or windshield washer fluid outside of its specified function and vehicle location. 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 Guide. The coolant concentration should be maintained at 50%. 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. 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. If the level is below the MIN mark, add engine coolant immediately see Adding coolant in this chapter. Adding coolant WARNING: Do not add coolant when the engine is hot. Steam and scalding liquids released from a hot cooling system can burn you badly. Also, you can be burned if you spill coolant on hot engine parts. WARNING: Do not put coolant in the windshield washer fluid container. If sprayed on the windshield, coolant could make it difficult to see through the windshield. 47 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)
