Maintenance Only use oils certified for gasoline engines by the American Petroleum Institute (API). An oil with this trademark symbol conforms to the current engine and emission system protection standards and fuel economy requirements of the International Lubricants Specification Advisory Council (ILSAC), comprised of U.S. and Japanese automobile manufacturers. 1. Remove the filler cap. 2. Add engine oil that meets the Ford specifications. See Capacities and Specifications (page 327). 3. Replace the filler cap. Turn it until you feel a strong resistance. Note: Coolant expands when it is hot. The level may extend beyond the MAX mark Note: If the level is at the MIN mark, below the MIN mark, or empty, add coolant immediately. See Adding Engine Coolant in this chapter. The coolant concentration should be maintained within 48% to 50%, which equates to a freeze point between -30°F degrees (-34ºC) and -34ºF (-37ºC). Note: For best results, coolant concentration should be tested with a refractometer such as Rotunda tool 300-ROB75240 available from your authorized dealer. Ford does not recommend the use of hydrometers or coolant test strips for measuring coolant concentrations. Note: Automotive fluids are not interchangeable. Do not use engine coolant or antifreeze or windshield washer fluid outside of its specified function and vehicle location. OIL CHANGE INDICATOR RESET To reset the oil monitoring system after an oil change, See General Information (page 101). ENGINE COOLANT CHECK Checking the Engine Coolant When the engine is cold, check the concentration and level of the engine coolant at the intervals listed in the scheduled maintenance information. See Scheduled Maintenance (page 436). Note: Make sure that the level is between the MIN and MAX marks on the coolant reservoir. Adding Engine Coolant WARNINGS Do not add engine coolant when the engine is hot. Steam and scalding liquids released from a hot cooling system can burn you badly. Also, you can be burned if you spill coolant on hot engine parts. 270 MKZ (CC9)
