2000 Mercury Mystique cooling

Controls and features
32• DEF – Distributes outside air
through the windshield defroster
ducts. It can be used to clear ice or
fog from the windshield. If the
temperature is about 10°C (50°F)
or higher, the air conditioner will
automatically dehumidify the air to
reduce fogging.
Operating tips
• In humid weather, select DEF
before driving. This will reduce
fogging on your windshield. After a
few minutes, select any desired
position.
• To reduce humidity buildup
inside the vehicle, don’t drive with
the climate control system in the
OFF position.
• Don’t put objects under the front
seat that will interfere with the
airflow to the back seats.
• Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield under the
hood).
• If your vehicle has been parked
with the windows closed during hot
weather, the air conditioner will do
a much faster job of cooling if you
drive for two or three minutes with
the windows open. This will force
most of the hot, stale air out of the
vehicle. Then operate your air
conditioner as you would normally.

3. Park the booster vehicle close to
the hood of the disabled vehicle,
making sure the two vehicles do
nottouch. Set the parking brake
on both vehicles and stay clear of
the engine cooling fan and other
moving parts.
4. Check all battery terminals and
remove any excessive corrosion
before you attach the battery
cables. Ensure that vent caps are
tight and level.
5. Turn the heater fan on in both
vehicles to protect from any
electrical surges. Turn all other
accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster
cable to the positive (+) terminal of
the discharge battery.
Note:In the illustrations,
“lightning bolts” are used to
designate the assisting (boosting)
battery.

Maintenance and care
163 Precautions when servicing
your vehicle
Be especially careful when
inspecting or servicing your
vehicle. Here are some general
precautions for your safety:
• Do not work on a hot engine.
The cooling fan is automatic
and may come on at any
time. Always disconnect the
negative terminal of the battery
before working near the fan.
• If you must work with the engine
running, avoid wearing loose
clothing or jewelry that could get
caught in moving parts. Take
precautions with long hair.
• Do not work on a vehicle with the
engine running in an enclosed
space, unless you are sure you have
enough ventilation.
• Keep all lit cigarettes, open
flames and other lit material away
from the battery and all fuel related
parts.
If you disconnect the battery, the
engine must “relearn” its idle
conditions before your vehicle will
drive properly, as explained under
Battery in this chapter.

The importance of engine
coolant
Engine coolant provides freeze
protection, boil protection, cooling
efficiency and corrosion protection
to the engine and cooling
components. In order to obtain
these protections, the engine
coolant must be maintained at the
proper concentration and fluid
level in the coolant reservoir.
Your vehicle was factory-filled with
a 50/50 engine coolant and water
concentration. If the concentration
of coolant falls below 40 % or rises
above 60 %, the engine parts could
become damaged or not work
properly. A 50/50 mixture of
coolant and water provides the
following:
• Boiling protection up to 265°F
(129°C).
• Freeze protection down to -34°F
(-36°C).
• Protection against rust and other
forms of corrosion.
• Enables calibrated gauges to
function properly. Cooling system - engine coolant

Maintenance and care
174Checking 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
water, which equates to a freeze
point of -34°F (-36°C). 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“ or
“cold fill range“ level in the coolant
reservoir. If the level falls below,
add coolant per the instructions in
the Adding engine coolant
section.
Adding engine coolant
When adding engine 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 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.
The coolant system in your vehicle
is filled with Ford Premium Engine
Coolant E2FZ-19549-AA
(Motorcraft CXC-8-B in Canada) or
equivalent meeting Ford
specification ESE-M97B44-A.
To maintain the integrity of the
coolant and the cooling system
and maintain the warranty on
the cooling system:
•Add the type of coolant
originally equipped in your
vehicle. If you are unsure which
type of coolant your vehicle
requires, contact your local dealer.
•Do not mix the factory-filled
coolant with an orange-colored
EXTENDED LIFE COOLANT
such as F6AZ-19544-A, meeting
WSS-M97B44-D. Mixing of Ford
Premium Engine Coolant with an
extended life product can result in
degraded corrosion protection.
31MMCen 24.6.99 15:30 Uhr Seite 174

Maintenance and care
175 • 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 or
methanol 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 the bottle label
states compliance with Ford
specification ESE-M97B44-A.
