Maintenance 257 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. Used engine coolant should be disposed of in an appropriate manner. Follow your community's regulations and standards for recycling and disposing of automotive fluids. 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. What You Should Know About Fail-Safe Cooling If the engine coolant supply is depleted, this feature allows the vehicle to be driven temporarily before incremental component damage is incurred. The fail-safe distance depends on ambient temperatures, vehicle load and terrain. How Fail-Safe Cooling Works If the engine begins to overheat, the engine coolant temperature gauge will move to the red (hot) area and: The coolant temperature warning light will illuminate.
