ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36° C (-34° F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the “cold full” of “cold fill range” level in the
coolant reservoir. If the level falls below, refer to instructions in the
Adding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -36° C (-34° F).
•Boiling protection up to 129° C (265° F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “cold fill level” or within the “cold
fill range” as listed on the engine coolant reservoir (depending upon
application).
•Refer to the Scheduled Maintenance Guide for service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, refer toAdding engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
The cooling system in your vehicle is originally equipped with either:
•Green-colored Motorcraft Premium Engine Coolant, VC-4–A (U.S.) or
CXC-10 (Canada) meeting Ford specification ESE-M97B44–A or,
•Yellow-colored Motorcraft Premium Gold Engine Coolant, VC-7–A
(VC-7–B in Oregon), meeting Ford Specification WSS-M97B51–A1.
If you are unsure which type of coolant your vehicle requires, check your
coolant reservoir or contact your local dealer.
Note:Use of Motorcraft Cooling System StopLeak Pellets, VC-6,
darkens 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 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
Maintenance and Specifications
252

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 usealcohol, methanol, brine, extra inhibitors or additives in
the coolant system. These can cause engine damage.
•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled engine coolantsection).
Adding engine coolant
Only a qualified technician should add engine coolant to your
vehicle.If the coolant level is LOW or if there are any coolant system
problems, contact you local Lincoln dealer.
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.
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.
Recycled engine coolant
•Motorcraft Premium Engine Coolant (green-colored):For
vehicles equipped with this coolant, use only recycled engine coolant
produced by a Ford Motor Company approved process and meeting
specification ESE-M97B44–A.
•Motorcraft Premium Gold Engine Coolant yellow-colored):For
vehicles equipped with this coolant, do NOT use recycled engine
coolant since a Ford Motor Company approved recycling process is
not yet available.
Follow your community’s regulations and standards for disposing
and recycling of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toRefill capacitiesin this chapter.
Severe climates
If you drive in extremely cold (less than –36° C [–34° F]) or extremely
hot climates, it may be necessary to adjust the coolant concentration
levels.
Maintenance and Specifications
253

•Extreme cold:increase the coolant concentration above 50%.
NEVER increase the coolant concentration above 60%.
•Extreme hot:it is acceptable to decrease the coolant concentration
below 50%.NEVER decrease the coolant concentration below
40%.
The coolant concentration in severe climates must always be
between 40% and 60%.Coolant concentrations not within the
40%-60% range may cause engine damage.
Refer to the chart on the coolant container to ensure the coolant
concentration in your vehicle will provide adequate protection at the
temperatures in which you drive.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
and thesymbol
will illuminate.
•The “Service Engine Soon”
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature:
•The engine will completely shut down.
•Steering and braking effort will increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
Maintenance and Specifications
254

When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir capwhile the engine is
running or hot.
5. Restart the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
WHATYOU SHOULD KNOW ABOUTAUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel capto disengage in a collision, which may result in possible
personal injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Maintenance and Specifications
255

1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in
small amounts, continuously
checking the level until it reaches
the range between the MIN and
MAX lines. Be sure to put the cap
back on the reservoir.
BRAKE FLUID RESERVOIR
The fluid level will dropslowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the “MAX” line
that do not trigger the brake system
warning lampare within the normal
operating range, there is no need to
add fluid. If the fluid levels are outside of the normal operating range,
the performance of your brake system could be compromised, seek
service from your dealer immediately.
