Maintenance and Specifications Note: Automotive fluids are not interchangeable; do not use engine coolant or windshield washer fluid outside of its specified function and vehicle location. Adding coolant When adding coolant, make sure it is a 50/50 mixture of coolant and distilled water. Add the mixture to the coolant reservoir(s), when the engine is cool, until the appropriate fill level is obtained. If you have to add more than 1.0 quart (1.0 liter) of coolant per month, have your dealer check the cooling system. Your cooling system may have a leak. Operating an engine with a low level of coolant can result in engine overheating and possible engine damage. Note: If coolant is added to bring the level within the COLD FILL RANGE when the engine is not cold, the system will remain underfilled. WARNING: Do not add coolant when the engine is hot. Steam and scalding liquids released from a hot cooling system can burn you badly. Also, you can be burned if you spill coolant on hot engine parts. WARNING: Do not put coolant in the windshield washer fluid container. If sprayed on the windshield, coolant could make it difficult to see through the windshield. • Do not mix coolants. Add the coolant type originally equipped in your vehicle. Refer to Maintenance product specifications and capacities in this chapter for the proper coolant type. Note: Do not use stop leak pellets or cooling system sealants/additives as they can cause damage to the engine cooling and/or heating systems. This damage would not be covered under your vehicle's warranty. • A large amount of water without engine coolant may be added to the engine cooling system only, in case of emergency, to reach a vehicle service location. Avoid this procedure if delivery to the service location requires heavy engine loads. In this instance, the cooling system(s) must be drained, chemically cleaned with Motorcraft௡ Engine Cooling System Iron Cleaner, and refilled with a 50/50 mixture of coolant and distilled water as soon as possible. Water alone (without coolant) can cause damage from corrosion, overheating or freezing. DO NOT use this method for the secondary cooling system. The secondary cooling system operates close to ambient temperature, and is susceptible to freezing in any subfreezing environment, in the absence of coolant. 47 2011 Diesel (eco) Supplement, 5th Printing USA (fus)

Note:
Automotive fluids are not interchangeable; do not use engine
coolant or windshield washer fluid outside of its specified function and
vehicle location.
Adding coolant
When adding coolant, make sure it is a 50/50 mixture of coolant and
distilled water. Add the mixture to the coolant reservoir(s),
when the
engine is cool
, until the appropriate fill level is obtained.
If you have to add more than 1.0 quart (1.0 liter) of coolant per month,
have your dealer check the cooling system. Your cooling system may
have a leak. Operating an engine with a low level of coolant can result in
engine overheating and possible engine damage.
Note:
If coolant is added to bring the level within the COLD FILL
RANGE when the engine is not cold, the system will remain underfilled.
WARNING:
Do not add coolant when the engine is hot. Steam
and scalding liquids released from a hot cooling system can burn
you badly. Also, you can be burned if you spill coolant on hot engine
parts.
WARNING:
Do not put coolant in the windshield washer fluid
container. If sprayed on the windshield, coolant could make it
difficult to see through the windshield.
•
Do not mix coolants. Add the coolant type originally equipped
in your vehicle.
Refer to
Maintenance product specifications and
capacities
in this chapter for the proper coolant type.
Note:
Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
•
A large amount of water without engine coolant may be added to the
engine cooling system only, in case of emergency, to reach a vehicle
service location. Avoid this procedure if delivery to the service location
requires heavy engine loads. In this instance, the cooling system(s)
