FORD 2013 Explorer v.4 - Manual (Page 339)

Adding Engine Oil
Note: Do not remove the filler cap when the engine is running.
Note: Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
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
WARNING: Do not allow the fluid to touch your skin or eyes.
If this happens, rinse the affected areas immediately with plenty
of water and contact your doctor.
WARNING: Make sure that the level is within the COLD FILL
RANGE.
Note: Coolant expands when it is hot. The level may extend beyond the
COLD FILL RANGE.
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 Rotunda tool 300-ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentration.
Note: Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
The concentration and level of engine coolant should be checked at the
intervals listed in scheduled maintenance information.
If the level is below the COLD FILL RANGE, add coolant immediately.
