2015 LINCOLN NAVIGATOR heating

•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 Specifications for 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%.
• 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.

Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and foreign material contamination should be inspected
immediately by a qualified expert, such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
every month or at six month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure.
Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary.
Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if
necessary.
Parking brake for proper operation.
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag, safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as
necessary.
