Note: Do not use stop leak pellets or cooling system sealants or
additives as they can cause damage to the engine cooling and heating
systems. Your vehicle's warranty does not cover this damage.
Note: During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require draining the engine coolant,
flushing the system, or replacing the engine coolant.
• DO NOT MIX different colors or types of coolant in your vehicle.
Make sure the correct coolant is used. Mixing of engine coolants may
harm your engine's cooling system. The use of an improper coolant
may harm engine and cooling system components and may void the
warranty. Use prediluted engine coolant meeting the Ford
specification. See the Capacities and Specifications chapter for
more information.
• In case of emergency, you may add a large amount of water without
engine coolant in order to reach a vehicle service location. In this
instance, drain the cooling system, chemically clean it with Motorcraft
Premium Cooling System Flush, and refill it with engine coolant as
soon as possible. Water alone (without engine coolant) can cause
engine damage from corrosion, overheating or freezing.
• Do not use alcohol, methanol, brine or any engine coolants mixed
with alcohol or methanol antifreeze (coolant). 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 engine
coolant.
Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specifications for more information.
Whenever you add coolant, 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.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-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.
