2009 Mercury Grand Marquis water pump

MULTI-FUNCTION LEVER
Windshield wiper:Rotate the end
of the control away from you to
increase the speed of the wipers;
rotate towards you to decrease the
speed of the wipers.
Windshield washer:Press the end
of the stalk:
•briefly: causes a single swipe of
the wipers without washer fluid.
•a quick press and hold: the
wipers will swipe three times with
washer fluid.
•a long press and hold: the wipers and washer fluid will be activated for
up to five seconds.
Courtesy wipe feature:One extra wipe will happen a few seconds
after washing the front window to clear any water that is dripping down
from the top of the windshield caused by the washing.
Note:Do not operate the washer when the washer reservoir is empty.
This may cause the washer pump to overheat. Check the washer fluid
level frequently. Do not operate the wipers when the windshield is dry.
This may scratch the glass, damage the wiper blades and cause the wiper
motor to burn out. Before operating the wiper on a dry windshield,
always use the windshield washer. In freezing weather, be sure the wiper
blades are not frozen to the windshield before operating the wipers.
Windshield wiper/washer features
When the windshield wipers are turned on during daylight, and the
headlamp control is in the autolamp position, the exterior lamps will turn
on after a brief delay and will remain on until the wipers are turned off.

however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
WARNING:If you are driving down a long or steep hill, shift to
a lower gear. Do not apply your brakes continuously, as they may
overheat and become less effective.
Under normal operating conditions, brake dust may accumulate on the
wheels. Some brake dust is inevitable as brakes wear and does not
contribute to brake noise. The use of modern friction materials with
emphasis on improved performance and environmental considerations
can lead to more dust than in the past. Brake dust can be cleaned by
weekly washing with soapy water and a soft sponge. Heavier deposits can
be removed with Motorcraft Wheel and Tire Cleaner (ZC-37–A).
Anti-lock brake system (ABS)
This vehicle is equipped with an anti-lock braking system (ABS). A noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle’s
anti-lock brake system. If the vehicle has continuous vibration or shudder
in the steering wheel while braking, the vehicle should be inspected by
an authorized dealer.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The

the advantage of an ABS equipped

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
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 H (hot) area.
•Theservice engine soon
indicator light will illuminate.
•The message center (if equipped) will display COOLANT OVER
TEMPERATURE.
•The
symbol 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, causing steering and braking
effort to increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
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 an authorized dealer.
