Maintenance and care concentration. It may take several drains and additions to obtain a 50/50 coolant concentration. Whenever coolant has been added, the coolant level in the coolant reservoir should be checked the next few times you drive the vehicle. If 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 liter (1.0 quart) 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 recommends the use of a recycled engine coolant produced by Ford-approved processes in vehicles originally equipped with Motorcraft Premium Engine Coolant (green-colored). However, not all coolant recycling processes produce coolant that meets Ford specification ESE-M97B44-A. Use of such coolant may harm the engine and cooling system components. 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 the Capacities and specifications chapter. Fill your engine coolant reservoir as outlined in Adding engine coolant in this chapter. Severe climates If you drive in extremely cold climates (less than -36° C [-34° F]): • It may be necessary to increase the coolant concentration above 50%. • NEVER increase the coolant concentration above 60%. 183
