2008 Acura MDX engine

If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.Fill the f uel tank. Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Leave the parking brake off. Put
the transmission in Park.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all. If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run. Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
Check these things:
Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page .
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. See on page . 421

´ ´ Start your vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.
The numbers in the illustration show
you the order to connect the jumper
cables.
Connect one jumper cable to the
positive ( ) terminal on your
vehicle’s battery. Connect the
other end to the positive ( )
terminal on the booster battery. Once the vehicle is running,
disconnect the negative cable f rom
your vehicle, then f rom the
booster battery. Disconnect the
positive cable f rom your vehicle,
and then from the booster battery.
Keep the ends of the jumper cables
away from each other and any metal

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
The pointer of your vehicle’s
temperature gauge should stay in
the midrange under most conditions.
If it climbs to the red mark, you
should determine the reason (hot
day, driving up a steep hill, etc.).
If the vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
Saf ely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn of f the
all accessories, and turn on the
hazard warning indicators.

If the temperature gauge stays at
the red mark, turn of f the engine.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (seeon page ).
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.Start the engine and set the
climate control to AUTO at ‘‘Hi.’’
Add coolant to the radiator up to
the base of the f iller neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
ref illed with the proper mixture as
soon as you can.
Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(see on page).
This indicator should never come on
when the engine is running. If it
starts flashing or stays on, the oil
pressure has dropped very low or
lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see a ‘‘CHECK
ENGINE OIL LEVEL’’ message on
the multi-information display when
this indicator comes on.
If the charging system indicator
comes on brightly when the engine
is running, the battery is not being
charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM’’ message on
the multi-information display (see
page ).
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
