Engine shield
Some vehicles may be equipped with an aero-shield under the engine.
This shield needs to be removed for service, including oil and filter
changes. It is secured with four quick release fasteners.

ENGINE OIL CHECK
Note:Check the level before starting the engine.
Note:Make sure that the level is between the MIN and MAX marks.
1. Make sure that your vehicle is on level ground.
2. Turn the engine off and wait 10 minutes for the oil to drain into the
oil pan.
3. Remove the dipstick and wipe it with a clean, lint-free cloth. Replace
the dipstick and remove it again to check the oil level.
If the level is at the MIN mark, add oil immediately.
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. SeeCapacities and
Specificationsfor more information.
3. Wipe off any spilled oil.
4. 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 inScheduled 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.

USA(fus)

If the level is below the COLD FILL RANGE, add coolant immediately.
SeeAdding Engine Coolantin 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. 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.
Adding Engine Coolant
WARNING: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.
WARNING: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.
WARNING: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 the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets, cooling system sealants or additives
as they can cause damage to the engine cooling or heating systems. This
damage would not be covered under your vehicle’s warranty.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.

•DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of engine coolants may harm
your engine’s cooling system. The use of an improper coolant may
harm engine and cooling system components and may void the
warranty.
•In case of emergency, a large amount of water without engine coolant
may be added in order to reach a vehicle service location. In this
instance, the cooling system must be drained, chemically cleaned with
Motorcraft Premium Cooling System Flush, and refilled with engine
coolant as soon as possible. Water alone (without engine coolant) can
cause engine damage from corrosion, overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the engine
coolant.
Unscrew the cap slowly. Any pressure will escape as you unscrew the
cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specificationsfor more information.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
318Maintenance
2015 Explorer(exp)
Owners Guide gf, 2nd Printing, September 2014
USA(fus)

•A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant concentrations above 60% will decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
freeze and corrosion protection characteristics of the engine coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme climates should use prediluted
engine coolant for optimum cooling system and engine protection.
Engine Fluid Temperature Management (If Equipped)
WARNING:To reduce the risk of collision and injury, be prepared
that the vehicle speed may reduce and the vehicle may not be able
to accelerate with full power until the fluid temperatures reduce.
Your vehicle has been designed to pull a trailer, but because of the added
load, the vehicle’s engine may temporarily reach higher temperatures
during severe operating conditions such as ascending a long or steep
grade while pulling a trailer in hot ambient temperatures.
At this time, you may notice your engine coolant temperature gauge
needle move toward the H and the POWER REDUCED TO LOWER
TEMP message may appear in the information display.
You may notice a reduction in the vehicle’s speed caused by reduced
engine power. Your vehicle has been designed to enter this mode if
certain high temperature/high load conditions take place in order to
manage the engine’s fluid temperatures. The amount of speed reduction
will depend on the vehicle loading, towing, grade, ambient temperature,
and other factors. If this occurs, there is no need to pull off the road.
The vehicle can continue to be driven while this message is active.
The air conditioning may also cycle on and off during severe operating
conditions to protect overheating of the engine. When the engine coolant
temperature decreases to a more normal operating temperature, the air
conditioning will turn on once again.
