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, spilling coolant on hot engine parts can burn you.|
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.
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 you loosen the cap slightly.
Do not add coolant further than the MAX mark.
When the engine is cold, check the concentration and level of the coolant at the intervals listed in the scheduled maintenance information. See
Make sure that the coolant level is between the MIN and MAX marks on the coolant reservoir.
Coolant expands when it is hot.The level may extend beyond the MAX mark.
Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -30°F (-34°C) and -34°F (-37°C). Coolant concentration should be checked using a refractometer. We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentration.
Adding Engine Coolant
Never remove the coolant reservoir cap while the engine is running or hot.|
Automotive fluids are not interchangeable. Do not use coolant or windshield washer fluid outside of its specified function and vehicle location.
Do not use stop leak pellets, cooling system sealants, or non-specified additives as they can cause damage to the engine cooling or heating systems.Resulting component damage may not be covered by the vehicle Warranty.
It is very important to use prediluted coolant approved to the correct specification in order to avoid plugging the small passageways in the engine cooling system. See
Capacities and Specifications
Do not mix different colors or types of coolant in your vehicle. Mixing of engine coolants or using an incorrect coolant may harm the engine or cooling system components and may not be covered by the vehicle Warranty.
If prediluted coolant is not available, use the approved concentrated coolant diluting it to 50/50 with distilled water. See
Capacities and Specifications.
Using water that has not been deionised may contribute to deposit formation, corrosion and plugging of the small cooling system passageways.
Coolants marketed for all makes and models may not be approved to Ford specifications and may cause damage to the cooling system. Resulting component damage may not be covered by the vehicle Warranty.
If the coolant level is at or below the minimum mark, add prediluted coolant immediately.
To top up the coolant level do the following:
- Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
- Add prediluted coolant approved to the correct specification. See
Capacities and Specifications.
- Add enough prediluted coolant to reach the correct level.
- Replace the coolant reservoir cap, turn it clockwise until you feel a strong resistance.
- Check the coolant level in the coolant reservoir the next few times you drive your vehicle. If necessary, add enough prediluted engine coolant to bring the coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of engine coolant per month, have your vehicle checked as soon as possible. Operating an engine with a low level of coolant can result in engine overheating and possible engine damage.
During normal vehicle operation, the coolant may change color from orange to pink or light red. As long as the coolant is clear and uncontaminated, this color change does not indicate the coolant has degraded nor does it require the coolant to be drained, the system to be flushed, or the coolant to be replaced.
In case of emergency, you can add a large amount of water without coolant in order to reach a vehicle service location. Water alone, without coolant, can cause engine damage from corrosion, overheating or freezing. When you reach a service location, you must have the cooling system drained and refilled with prediluted coolant approved to the correct specification. See
Capacities and Specifications.
Do not use the following as a coolant substitute:
- Any coolant mixed with alcohol or methanol antifreeze.
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 coolant.
We do not recommend the use of recycled coolant as an approved recycling process is not yet available.
Dispose of used engine coolant in an appropriate manner. Follow your community’s regulations and standards for recycling and disposing of automotive fluids.
If you drive in extremely cold climates:
- It may be necessary to increase the coolant concentration above 50%.
- A coolant concentration of 60% provides improved freeze point protection. Coolant concentrations above 60% decrease the overheat protection characteristics of the coolant and may cause engine damage.
If you drive in extremely hot climates:
- You can decrease the coolant concentration to 40%.
- Coolant concentrations below 40% decrease the freeze and corrosion protection characteristics of the coolant and may cause engine damage.
Vehicles driven year-round in non-extreme climates should use prediluted coolant for optimum cooling system and engine protection.
At specific mileage intervals, as listed in the scheduled maintenance information, the coolant should be changed. Add prediluted coolant approved to the correct specification. See
Capacities and Specifications
Fail-safe cooling allows you to temporarily drive your vehicle before any incremental component damage occurs. The fail-safe distance depends on ambient temperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolant temperature gauge moves toward the red zone:
A warning lamp illuminates and a message may appear in the information display.
If the engine reaches a preset over-temperature condition, the engine automatically switches to alternating cylinder operation. Each disabled cylinder acts as an air 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 engine temperature, causing the engine to completely shut down. Your steering and braking effort increases in this situation.
When the engine temperature cools, you can re-start the engine. Have your vehicle checked as soon as possible to minimize engine damage.
When Fail-Safe Mode Is Activated
Fail-safe mode is for use during emergencies only. Operate your vehicle in fail-safe mode only as long as necessary to bring your vehicle to rest in a safe location and seek immediate repairs. When in fail-safe mode, your vehicle will have limited power, will not be able to maintain high-speed operation, and may completely shut down without warning, potentially losing engine power, power steering assist, and power brake assist, which may increase the possibility of a crash resulting in serious injury.|
Never remove the coolant reservoir cap while the engine is running or hot.
Your vehicle has limited engine power when in the fail-safe mode, drive your vehicle with caution. Your vehicle does not maintain high-speed operation and the engine may operate poorly.
Remember that the engine is capable of automatically shutting down to prevent engine damage. In this situation:
- Pull off the road as soon as safely possible and switch the engine off.
- If you are a member of a roadside assistance program, we recommend that you contact your roadside assistance service provider.
- If this is not possible, wait a short period for the engine to cool.
- Check the coolant level. If the coolant level is at or below the minimum mark, add prediluted coolant immediately.
- When the engine temperature cools, you can re-start the engine. Have your vehicle checked as soon as possible to minimize engine damage.
Driving your vehicle without repair increases the chance of engine damage.
Engine Coolant Temperature Management (If Equipped)
To reduce the risk of crash and injury, be prepared that the vehicle speed may reduce and the vehicle may not be able to accelerate with full power until the coolant temperature reduces.|
If you tow a trailer with your vehicle, the engine may temporarily reach higher a temperature during severe operating conditions, for example ascending a long or steep grade in high ambient temperatures.
At this time, you may notice the coolant temperature gauge moves toward the red zone and a message may appear in the information display.
You may notice a reduction in vehicle speed caused by reduced engine power. In order to manage the engine coolant temperature. Your vehicle may enter this mode if certain high-temperature and high-load conditions take place. The amount of speed reduction depends on vehicle loading, grade and ambient temperature. If this occurs, there is no need to pull off the road. You can continue to drive your vehicle.
The air conditioning may automatically turn on and off during severe operating conditions to protect the engine from overheating. When the coolant temperature decreases to the normal operating temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully into the red zone, or if the coolant temperature warning or service engine soon messages appear in your information display, do the following:
- Pull off the road as soon as safely possible and shift the transmission into park (P).
- Leave the engine running until the coolant temperature gauge needle returns to the normal position. After several minutes, if the temperature does not drop, follow the remaining steps.
- Switch the engine off and wait for it to cool. Check the coolant level.
- If the coolant level is at or below the minimum mark, add prediluted coolant immediately.
- If the coolant level is normal, restart the engine and continue.
