2018 LINCOLN NAVIGATOR coolant level

4. Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have your vehiclechecked as soon as possible. Operating anengine with a low level of coolant can resultin engine overheating and possible enginedamage.
Note:If your vehicle has orange coolant,during normal vehicle operation, the coolantmay change color from orange to pink orlight red. As long as the coolant is clear anduncontaminated, this color change does notindicate the coolant has degraded nor doesit require the coolant to be drained, thesystem to be flushed, or the coolant to bereplaced.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location. Inthis instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon aspossible.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling process isnot yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60% providesimproved freeze point protection. Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause engine damage.

Maintenance

Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait a short periodfor the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).

Maintenance

2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperature doesnot drop, follow the remaining steps.
3. Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restart theengine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer checkand change the transmission fluid at thecorrect service interval. See ScheduledMaintenance (page 552).
The automatic transmission does not havea transmission fluid dipstick.
Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes. Your transmission doesnot consume fluid. However, if thetransmission slips, shifts slowly or if younotice a sign of leaking fluid, contact anauthorized dealer.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.

Cooling system
•Protect against freezing temperatures.
•When removing your vehicle fromstorage, check coolant fluid level.Confirm that there are no cooling systemleaks and that fluid is at therecommended level.
Battery
•Check and recharge as necessary. Keepconnections clean.
•If storing your vehicle for more than 30days without recharging the battery, werecommend that you disconnect thebattery cables to maintain battery chargefor quick starting.
Note:It is necessary to reset memoryfeatures if battery cables are disconnected.
Brakes
•Make sure the brakes and parking brakerelease fully.
Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure all linkages, cables, levers andpins under your vehicle are covered withgrease to prevent rust.
•Move vehicles at least 25 ft (7.5 m) every15 days to lubricate working parts andprevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out ofstorage, do the following:
•Wash your vehicle to remove any dirt orgrease film build-up on window surfaces.
•Check windshield wipers for anydeterioration.
•Check under the hood for any foreignmaterial that may have collected duringstorage such as mice or squirrel nests.
•Check the exhaust for any foreignmaterial that may have collected duringstorage.
•Check tire pressures and set tire inflationper the Tire Label.
•Check brake pedal operation. Drive yourvehicle 15 ft (4.5 m) back and forth toremove rust build-up.
•Check fluid levels (including coolant, oiland gas) to make sure there are no leaks,and fluids are at recommended levels.
•If you remove the battery, clean thebattery cable ends and check fordamage.
Contact an authorized dealer if you have anyconcerns or issues.

MAINTENANCE
Intelligent Oil-Life Monitor
Your vehicle is equipped with an IntelligentOil-Life Monitor that determines when youshould change the engine oil based on howyour vehicle is used. By using severalimportant factors in its calculations, themonitor helps reduce the cost of owning yourvehicle and reduces environmental waste atthe same time.
This means you do not have to remember tochange the oil on a mileage-based schedule.Your vehicle lets you know when an oilchange is due by displaying a message inthe information display.
The following table provides examples ofvehicle use and its impact on oil changeintervals. It is a guideline only. Actual oilchange intervals depend on several factorsand generally decrease with severity of use.
