Maintenance • Do not use alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze (coolant). Alcohol and other liquids can cause engine damage from overheating or freezing. Do not add extra inhibitors or additives to the coolant. These can be harmful and compromise the corrosion protection of the engine coolant. 3. Close the inverter system controller coolant reservoir cap. Whenever you add coolant, check the coolant level in the inverter system controller coolant reservoir the next few times you drive the vehicle. If necessary, add enough prediluted coolant to bring the inverter system controller coolant level to the proper level. • Adding Engine Coolant Unscrew the engine coolant reservoir cap slowly. Any pressure will escape as you unscrew the cap. 2. Use a funnel to add prediluted engine coolant to the engine coolant reservoir. Make sure that the level is between the MIN and MAX marks on the engine coolant reservoir. Use prediluted engine coolant meeting the Ford specification. See Capacities and Specifications (page 265). 3. Close the engine coolant reservoir cap. Whenever you add coolant, check the coolant level in the engine coolant reservoir the next few times you drive the vehicle. If necessary, add enough prediluted engine coolant to bring the engine coolant level to the proper level. 1. 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 an authorized Ford 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 an authorized Ford 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. Adding Inverter System Controller Coolant 1. Open the inverter system controller coolant reservoir cap. 2. Use a funnel to add prediluted coolant to the inverter system controller coolant reservoir. Make sure that the level is between the MIN and MAX marks on the inverter system controller coolant reservoir. Use prediluted coolant meeting the Ford specification. See Capacities and Specifications (page 265). 215 C-MAX (CCG)
