Maintenance and Specifications distilled water. Use distilled water. If distilled water is unavailable, water meeting the requirements of Rotunda 328-00007, is sufficient for vehicle use. Using water that fails to meet the requirements can lead to coolant passage scaling and degrade the engine's durability and performance. • Rotunda 328-00008 (Antifreeze Coolant ELC Contamination Kit) - Evaluates the coolant concentration (freeze point protection) and additive strength (corrosion inhibitor) for overall coolant health. Note that the first step is to verify that the vehicle's coolant concentration is in the window of 40 - 60%. If the concentration falls outside of that window, the evaluation of the corrosion inhibitor strength will not be valid. If the report results in a pass the cooling system does not show excessive contamination. No action is required. If the report results as insufficient, the corrosion inhibitor (additive) strength of the coolant is too low. Add entire contents of one bottle of Motorcraft Specialty Orange Engine Coolant Revitalizer to the coolant reservoir. 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 with distilled water and coolant concentrate (Motorcraft Specialty Orange Engine Coolant). • 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 with distilled water and coolant concentrate (Motorcraft Specialty Orange Coolant). 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. 50 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
