Maintenance and Specifications Recycled engine coolant Ford Motor Company does not recommend the use of recycled engine coolant since a Ford-approved recycling process is not yet available. Always dispose of used automotive fluids in a responsible manner. Follow your community's regulations and standards for recycling and disposing of automotive fluids. Coolant refill capacity To find out how much fluid your vehicle's cooling system can hold, refer to Maintenance product specifications and capacities in this chapter. If your vehicle is equipped with a diesel engine, refer to the Maintenance product specifications and capacities section of your diesel supplement. Fill your engine coolant reservoir as outlined previously in the Adding engine coolant section. Severe climates If you drive in extremely cold climates: • It may be necessary to have a Ford authorized dealer increase the coolant concentration above 50%. • A coolant concentration of 60% will provide improved freeze point protection. Engine coolant concentrations above 60% will decrease the overheat protection characteristics of the engine coolant and may cause engine damage. If you drive in extremely hot climates: • It may be necessary to have a Ford authorized dealer decrease the coolant concentration to 40%. • A coolant concentration of 40% will provide improved overheat protection. Engine coolant concentrations below 40% will decrease the corrosion/freeze protection characteristics of the engine coolant and may cause engine damage. Vehicles driven year-round in non-extreme climates should use prediluted engine coolant for optimum cooling system and engine protection. 383 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
