Maintenance and care If you must remove the coolant reservoir cap, follow these steps to avoid personal injury: 1. Before you remove the cap, turn the engine off and let it cool. 2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise until pressure begins to release. 3. Step back while the pressure releases. 4. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. Change your engine coolant according to the appropriate schedule listed in the Scheduled Maintenance Guide. Before adding engine coolant, check the color of the coolant in your vehicle. For vehicles with green coolant, use Ford Premium Cooling System Fluid E2FZ-19549-AA (in Canada, Motorcraft CXC-8-B) or an equivalent premium engine coolant that meets Ford specification ESE-M97B44-A. Do not add orange coolant or recycled coolant to your vehicle originally equipped with conventional green coolant. For vehicles with orange coolant, use Ford Extended Life Engine Coolant F6AZ-19544-AA or a DEX-COOL௡ equivalent that meets Ford specification WSS-M97B44-D. Do not add conventional green coolant or recycled coolant to your vehicle originally equipped with orange coolant. Do not use alcohol or methanol antifreeze or any engine coolants mixed with alcohol or methanol antifreeze. Do not use supplemental coolant additives in your vehicle. These additives may harm your engine cooling system. The use of an improper coolant may void your warranty of your vehicle's engine cooling system. Recycled engine coolant Ford Motor Company recommends that Ford and Lincoln-Mercury dealers use recycled engine coolant produced by Ford-approved processes. For vehicles with green coolant, not all coolant recycling processes produce coolant which meets Ford specification ESE-M97B44-A, and use of such coolant may harm engine and cooling system components. 212
