check engine Acura TL 2002 3.2 Owner's Guide

If the temperature gauge stays at
the red mark, turn of f the engine.
Wait until you see no more signs
of steam or spray, then open the
hood.
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 there was no coolant in the
reserve tank, you may also have 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. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes
off.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks. Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). 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.
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. Put the radiator cap back on
tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See
on page .)

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or a moment, then
recovered. If the indicator stays on
with the engine running, it shows
that the engine has lost oil pressure
and serious engine damage is
possible. In either case, you should
take immediate action.Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
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 the light
does not go out within ten 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 .)
Letthecarsitforaminute.Open
the hood and check the oil level
(see page ). Although oil level
and oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during
cornering and other driving
maneuvers.

This indicator comes on f or a f ew
seconds when you turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the
engine’s emissions control systems
may have a problem. Even though
you may f eel no dif f erence in your
car’s perf ormance, it can reduce
your f uel economy and cause your
car to put out excessive emissions.
Continued operation may cause
serious damage.Youshouldalsohavethedealer
inspect your car if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving. If the indicator remains on past three
driving trips, or the f uel cap was not
loose or missing, have the car
checked by the dealer as soon as
possible. Drive moderately until the
dealer has inspected the problem.
Avoid full-throttle acceleration and
driving at high speed. If you have recently ref ueled your
car, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
and tighten it until it clicks several
times. Replace the fuel fill cap if it is
missing. Tightening the cap will not
make the indicator turn of f
immediately; it takes at least three
driving trips.

If you keep driving with the
malf unction indicator lamp on, you can
damage your car’s emissions controls
and engine. Those repairs may not be
covered by your car’s warranties.
00/12/25 14:42:01 31S0K630_296

Your car has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If your car’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.If possible, do not take your vehicle
f or a state emissions test until the
readiness codes are set. To check if
they are set, turn the ignition ON (II),
but do not start the engine. The
Malf unction Indicator Lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks 5 times, the readiness
codes are not set. Ref er to State
Emissions Testing f or more
inf ormation.(See page .)
