Adding Engine Coolant - Ford Explorer Sport Trac Owner's Manual

Adding engine coolant

When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir, when the
engine is cool, until the appropriate fill level is obtained.
Do not add engine 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.
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 Motorcraft Premium Gold Engine Coolant or equivalent
meeting Ford specification WSS-M97B51-A1. Refer to
Maintenance product specifications and capacities 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, or DEX-COOL brand with the
factory-filled coolant. Mixing Motorcraft Specialty Orange Engine
Coolant or any orange-colored extended life product such as
DEX-COOL brand 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.
