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. 189 F-650/750 (TBC) , enUSA, First Printing MaintenanceE211403 A B C E211404 165 4 32 7
WARNINGS 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 Scheduled Maintenance (page 316). Note: Make sure that the coolant level is between the MIN and MAX marks on the coolant reservoir. Note: 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 Coolant WARNING Never remove the coolant reservoir cap while the engine is running or hot. Note: Automotive fluids are not interchangeable. Do not use coolant or windshield washer fluid outside of its specified function and vehicle location. Note: 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 (page 258). 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. Note: 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. For vehicles with overflow coolant systems with a non-pressurized cap on the coolant recovery system, add coolant to the coolant recovery reservoir when the engine is cool. Add prediluted coolant to the maximum level. For all vehicles which have a coolant degas system with a pressurized cap, or if it is necessary to remove the coolant pressure relief cap on the radiator, follow these steps to add engine coolant: 1. Turn the engine off and let it cool. 2. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap. 3. Fill the coolant reservoir slowly with prediluted engine coolant to within the minimum and maximum range on the engine coolant reservoir. If you removed the radiator cap in an overflow system, fill the radiator until 190 F-650/750 (TBC) , enUSA, First Printing Maintenance
the coolant is visible and the radiator is almost full. If coolant is added to bring the level within the minimum and maximum range when the engine is not cold, the system may remain underfilled. 4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong resistance. 5. 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 proper level. Note: If prediluted coolant is not available, use the approved antifreeze concentrate diluting it to 50/50 with distilled water. See Capacities and Specifications (page 258). Using water that has not been deionised may contribute to deposit formation, corrosion or plugging of the small cooling system passageways. 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. Note: 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. Note: 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, flushed and refilled using the correct specification prediluted coolant or antifreeze concentrate. See Capacities and Specifications (page 258). Do not use the following as a coolant substitute: • Alcohol. • Methanol. • Brine. • 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. Recycled 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. 191 F-650/750 (TBC) , enUSA, First Printing Maintenance
Severe Climates 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 engine coolant for optimum cooling system and engine protection. Coolant Change At specific mileage intervals, as listed in the scheduled maintenance information, the coolant should be changed. The information display may display a message to change coolant at this time. Add prediluted coolant approved to the correct specification. See Capacities and Specifications (page 252). Engine-driven Cooling Fan (Fan Clutch) Your vehicle is equipped with an engine driven cooling fan drive (also called a fan clutch). This fan drive changes the fan speed to match the vehicle ’s changing cooling air flow requirements. Fan speed, fan noise level and fuel consumption all will increase based on the driving conditions that include trailer towing, hill climbing, heavy loads, high speed and high ambient temperature, individually or in combination. The fan drive is designed to provide the minimum fan speed (and resulting minimum fan noise and fuel consumption) required to meet the ever changing vehicle cooling air flow requirements. You will hear the amount of fan noise increasing and decreasing as the engine power requirements and vehicle driving conditions change as you drive. This is to be expected as being normal to the operation of your vehicle. High levels of fan noise might also be heard when your engine is first started, and should normally decrease after driving for a short time. Fail-Safe Cooling 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. 192 F-650/750 (TBC) , enUSA, First Printing Maintenance
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 WARNINGS 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: 1. Pull off the road as soon as safely possible and switch the engine off. 2. If you are a member of a roadside assistance program, we recommend that you contact your roadside assistance service provider. 3. If this is not possible, wait a short period for the engine to cool. 4. Check the coolant level. If the coolant level is at or below the minimum mark, add prediluted coolant immediately. 5. When the engine temperature cools, you can re-start the engine. Have your vehicle checked as soon as possible to minimize engine damage. Note: Driving your vehicle without repair increases the chance of engine damage. Engine Coolant Temperature Management (If Equipped) WARNING 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. 193 F-650/750 (TBC) , enUSA, First Printing Maintenance
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: 1. Pull off the road as soon as safely possible and shift the transmission into park (P). 2. 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. 3. Switch the engine off and wait for it to cool. Check the coolant level. 4. If the coolant level is at or below the minimum mark, add prediluted coolant immediately. 5. If the coolant level is normal, restart the engine and continue.

Engine and Secondary Cooling System Refill Procedure The following procedure should be used when refilling the engine or secondary cooling systems after it has been drained or become extremely low: 1. Before you remove the cap, turn the engine off and let it cool. 2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise until pressure begins to release. 3. Step back while the pressure releases. 4. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. 5. Slowly add prediluted engine coolant to the coolant reservoir until the coolant level is within the minimum and maximum range as listed on the reservoir. 6. Reinstall the pressure relief cap. 7. Start and run the engine at 2000 rpm for 2 minutes. 8. Shut engine off, and remove the pressure relief cap as previously outlined. 9. If required, add prediluted engine coolant to the coolant reservoir until the coolant level is within the minimum and maximum range as listed on the reservoir. 10. Engine cooling system: Repeat Step 5 until the coolant level has stabilized (is no longer dropping after each step) and the upper radiator hose at the radiator is warm to the touch (indicating that the engine thermostat is open and coolant is flowing through the radiator). 196 F-650/750 (TBC) , enUSA, First Printing Maintenance
11. Check the secondary cooling system. Repeat Step 5 until the coolant level has stabilized (is no longer dropping after each step) and the lower passenger side of the secondary radiator is warm to the touch (indicating secondary thermostat is open and coolant is flowing through the entire system). 12. Reinstall the pressure relief cap. Shut the engine off and let it cool. 13. Check the coolant level in the reservoir before you drive your vehicle the next few times. 14. If necessary, add prediluted engine coolant to the coolant reservoir until the coolant level is within the minimum and maximum range as listed on the reservoir. After any coolant has been added, check the coolant concentration. Recycled 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. Severe Climates 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 engine coolant for optimum cooling system and engine protection. Checking Coolant Corrosion Inhibitor Additive Strength At specific mileage intervals as listed in the scheduled maintenance information chapter, the coolant corrosion inhibitor additive should be checked. An information message may display in the optional information display at this time. The purpose of checking is to verify the correct engine coolant concentration (freeze point protection) and corrosion inhibitor additive level (strength) of the coolant for maximum engine performance and protection. Three products are available to confirm the life and health of the coolant, one tool, a test kit and a coolant inhibitor additive: 197 F-650/750 (TBC) , enUSA, First Printing Maintenance
