Maintenance and Specifications
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.
• Add antifreeze/coolant that meets the material and design
specifications for your vehicle. Refer to Lubricant specifications
in this chapter.
Note: Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification, WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
• Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, with the factory-filled coolant.
Mixing Motorcraft Specialty 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, 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.
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 the proper mixture of coolant and
water to the "FULL COLD" level. For all other 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 of a vehicle with
an overflow system, follow these steps to add engine coolant.
