Maintenance 287 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 Ford specifications. See Capacities and Specifications for more information. 3. Replace the filler cap. Turn it until you feel a strong resistance. ENGINE COOLANT CHECK Checking the Engine Coolant The concentration and level of engine coolant should be checked at the intervals listed in Scheduled Maintenance Information. Note: Make sure that the level is at the FULL COLD level or within the COLD FILL RANGE in the coolant reservoir. Note: Coolant expands when it is hot. The level may extend beyond the COLD FILL RANGE. If the level is below the COLD FILL RANGE, 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 (-34°C) and -34°F (-37°C). Note: For best results, coolant concentration should be tested with a refractometer such as Robinair Coolant and Battery Refractometer 75240. We do 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/antifreeze or windshield washer fluid outside of its specified function and vehicle location. 2015 Taurus Owners Guide gf, 1st Printing, April 2014 USA (fus)
