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. Check the engine oil level. 2. If the engine oil level is not within the normal range, add engine oil that meets Ford specifications. See Capacities and Specifications (page 359). 3. Remove the engine oil filler cap and use a funnel to pour the engine oil into the opening. 4. Wipe off any spilled oil. 5. Recheck the engine oil level. Make sure the oil level is not above the normal operating range on the engine oil level dipstick. 6. Install the engine oil level dipstick and ensure it is fully seated. 7. Fully install the engine oil filler cap by turning the filler cap clockwise until three clicks are heard or until the cap is fully seated. WARNINGS To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure. Steam and hot liquid can come out forcefully when you loosen the cap slightly. Do not add coolant further than the MAX mark. 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 518). Note: Make sure that the coolant level is between the MIN and MAX marks on the coolant reservoir. 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. Maintain coolant concentration 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. ENGINE COOLANT CHECK 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, spilling coolant on hot engine parts can burn you. Do not put engine coolant in the windshield washer fluid container. If sprayed on the windshield, engine coolant could make it difficult to see through the windshield. 303 F-150 (), enUSA, First Printing
