engine coolant LINCOLN MKZ HYBRID 2019 User Guide

When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 486).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We do not recommendthe use of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
WARNING: Do not add engine coolantwhen the engine is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Never remove the coolantreservoir cap when the engine is running orhot.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use prediluted coolantapproved to the correct specification in orderto avoid plugging the small passageways inthe engine cooling system. See Capacitiesand Specifications (page 357). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 353).Using water that has not been deionizedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 353).
3.Add enough prediluted coolant to reachthe correct level.

Maintenance

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:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
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 cooling system.
3. Refill with prediluted coolant as soon aspossible.
Water alone, without coolant, can causeengine damage from corrosion, overheatingor 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.

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing
Maintenance

If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of the coolantand may cause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
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 (page353).
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 coolanttemperature gauge moves toward the redzone:
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 in asafe location and seek immediate repairs.When in fail-safe mode, your vehicle will havelimited power, will not be able to maintainhigh-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
WARNING: Never remove the coolantreservoir cap when the engine is running orhot.

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 of crashand injury, be prepared that the vehiclespeed may reduce and the vehicle may notbe able to accelerate with full power until thecoolant temperature reduces.
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 pull off the road. You cancontinue to drive your vehicle.
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. Pull off the road as soon as safelypossible and shift the transmission intopark (P).

Maintenance

2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop after severalminutes, 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
Note:Transmission fluid should be checkedby an authorized dealer. If required, fluidshould be added by an authorized dealer.
Have an authorized dealer check and changethe transmission fluid at the correct serviceinterval. See Maintenance (page 298). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,(i.e., if the transmission slips or shifts slowly)or if you notice some sign of fluid leakage.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.
BRAKE FLUID CHECK
WARNING: Do not use any fluid otherthan the recommended brake fluid as thiswill reduce brake efficiency. Use of incorrectfluid could result in the loss of vehiclecontrol, serious personal injury or death.
WARNING: Only use brake fluid froma sealed container. Contamination with dirt,water, petroleum products or other materialsmay result in brake system damage or failure.Failure to adhere to this warning could resultin the loss of vehicle control, seriouspersonal injury or death.
WARNING: Do not allow the fluid totouch your skin or eyes. If this happens, rinsethe affected areas immediately with plentyof water and contact your physician.
WARNING: A fluid level between theMAX and MIN lines is within the normaloperating range and there is no need to addfluid. A fluid level not in the normal operatingrange could compromise the performanceof the system. Have your vehicle checkedimmediately.
To avoid fluid contamination, the reservoircap must remain in place and fully tight,unless you are adding fluid.
