FORD 2001 F-550 v.1 - Manual (Page 199)

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.
The cooling system in your vehicle is filled with green-colored Motorcraft
Premium Engine Coolant meeting Ford Specification ESE-M97B44–A. To
determine your vehicle’s coolant type (color), check your coolant
reservoir.
To maintain the integrity of the coolant and the cooling system
and maintain the warranty on the cooling system:
• Add Motorcraft Premium Engine Coolant (green-colored),
VC-4–A (US) or CXC-10 (Canada), or the type of coolant
originally equipped in your vehicle. If you are unsure which type
of coolant your vehicle requires, check your coolant reservoir or
contact your local dealer.
• Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Speciality Orange Engine Coolant, VC-2 (US) or
CXC-209 (Canada), meeting Ford specification WSS-M97B44–D
with the factory-filled coolant. Mixing Motorcraft Speciality Orange
Engine Coolant or any orange-colored extended life product with your
factory filled coolant can result in degraded corrosion protection.
• A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
• Do not use alcohol, methanol or 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.
• Do not mix with recycled coolant unless from a Ford-approved
recycling process (see Use of Recycled Engine Coolant section).
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
