2019 LINCOLN NAVIGATOR coolant temperature

Coolant Change
At specific mileage intervals, as listed in thescheduled maintenance information, thecoolant should be changed. Add predilutedcoolant approved to the correct specification.See Capacities and Specifications (page418).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, your vehicle willhave limited power, will not be able tomaintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the coolingsystem is hot. Wait 10 minutes for thecooling system to cool down. Cover thecoolant reservoir cap with a thick cloth toprevent the possibility of scalding andslowly remove the cap. Failure to followthis instruction could result in personalinjury.

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 547).
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.
BODY STYLING KITS
The distance between the underside of yourvehicle and the ground is less than that ofother models. Drive with extreme care toavoid damage to your vehicle.
