Extended life engine coolant
The cooling system in your vehicle is filled with yellow-colored
Motorcraft Premium Gold Engine Coolant meeting Ford Specification
WSS-M97B51–A1.
•Add Motorcraft Premium Gold Engine Coolant
(yellow-colored), VC-7–A (VC-7–B in Oregon).
Note:Use of Motorcraft Cooling System Stop Leak Pellets, VC-6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•
Do not add/mix extended life coolants such as Motorcraft
Speciality Orange Engine Coolant, VC-2 (U.S.) or CXC-209
(Canada), meeting Ford specification WSS-M97B44–D, with the
factory-fill coolant, Motorcraft Premium Gold Coolant meeting
Ford Specification WSS-M97B51–A.Mixing Motorcraft Speciality
Orange Engine Coolant or any equivalent extended life engine coolant
with this factory-fill 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 (seeUse of Recycled Engine Coolantsection).
Coolant condition inspection
Engine cooling systems should be checked twice a year to assure proper
glycol/water concentrations. a 50/50 mixture is recommended and
provides freeze protection in weather conditions as low as–36°C (-34°F)
as well as optimum corrosion protection. For vehicle operating in
extremely cold climate, a concentration of 60% ethylene glycol will
provide freeze protection in weather conditions as low as–51°C (-59°F).
Concentrations greater than 60% glycol are not recommended.

Fan clutches
Your vehicle’s cooling system is equipped with a viscous fan clutch.
•The fan clutch helps control cooling, increase performance, improve
fuel economy and reduce noise.
•The fan clutch is controlled by bimetallic spring sensors. Do not
tamper with these sensors as this may change their calibration or keep
the fan clutch from operating at all.
Stay clear of the fan/fan area while the engine is running or
possible personal injury may occur.
WINDSHIELD WASHER FLUID
Inspect the solution level in the
washer reservoir when insufficient
solution is sprayed.
Use 3.8L (4.0 quarts) of windshield
washer fluid that meets the Ford
specification listed. Refer to
Lubricant specificationsin this
chapter.
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
Do not put engine coolant in the washer fluid reservoir. Engine
coolant can severely reduce visibility if sprayed on the
windshield.
