Maintenance and Specifications necessary, add enough 50/50 concentration of engine coolant and distilled water to bring the liquid level to the proper level. If you have to add more than 1.0 quart (1.0 liter) of engine coolant per month, have your dealer check the engine cooling system. Your cooling system may have a leak. Operating an engine with a low level of coolant can result in engine overheating and possible engine damage. Recycled engine coolant Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles originally equipped with Motorcraft Premium Gold 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. Coolant refill capacity To find out how much fluid your vehicle's cooling system can hold, refer to Refill capacities in this section. Fill your engine coolant reservoir as outlined in Adding engine coolant in this section. Severe climates If you drive in extremely cold climates (less than -34° F [-36° C ]): • It may be necessary to increase the coolant concentration above 50%. • NEVER increase the coolant concentration above 60%. • Increased engine coolant concentrations above 60% will decrease the overheat protection characteristics of the engine coolant and may cause engine damage. • Refer to the chart on the coolant container to ensure the coolant concentration in your vehicle will provide adequate freeze protection at the temperatures in which you drive in the winter months. If you drive in extremely hot climates: • It is still necessary to maintain the coolant concentration above 40%. • NEVER decrease the coolant concentration below 40%. 336 2005 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
