Maintenance and Specifications additive level (strength) of the coolant for maximum engine performance and protection. Three products are available for ensuring the life and health of the coolant: one tool, a test kit and a coolant inhibitor additive: • Rotunda tool ROB75240 available from your dealer - recommended refractometer to test coolant concentration. • Rotunda 328-00008 (Antifreeze Coolant ELC Contamination Kit) - Evaluates the corrosion inhibitor additive strength. Note the first step is to verify the vehicle's coolant concentration is in the correct range of 40 - 60%. Coolant concentrations outside this range will not provide valid test results. If the report results in a pass (i.e., the cooling system does not show excessive contamination/the corrosion inhibitor additive strength is sufficient), no action is required. If the report results as insufficient (does not pass), the corrosion inhibitor additive strength of the coolant is too low. If the ENGINE COOLING SYSTEM corrosion inhibitor additive strength is low, add 48 fluid oz. of Motorcraft Specialty Orange Engine Coolant Revitalizer. If the SECONDARY COOLING SYSTEM corrosion inhibitor additive strength is low, add 16 fluid oz. of Motorcraft Specialty Orange Engine Coolant Revitalizer. The coolant can be recharged with this additive up to two times before the coolant must be changed-out. When exchanging the full coolant volume, the system must be flushed and refilled per the instructions in the Workshop Manual. • Motorcraft Specialty Orange Engine Coolant Revitalizer - Additive to boost the corrosion inhibitor level based upon the test results of the Antifreeze Coolant ELC Contamination Kit. The revitalizer may be added two times over the life of the coolant. If additional dosages are required, the cooling system must be flushed and refilled per the instructions in the Workshop Manual. Refer to Maintenance product specifications and capacities in this chapter for the proper coolant and additive specifications. Coolant change At specific mileage intervals, as listed in the scheduled maintenance information, the coolant should be changed. The optional message center, if equipped, will also display the message COOLANT CHANGE REQUIRED at this time. Refer to Maintenance product specifications and capacities in this chapter for the proper coolant. 52 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)
