engine overheat HONDA CR-V 2002 RD4-RD7 / 2.G Owners Manual

The manual transmission is syn-
chronizedinallforwardgearsfor
smooth operation. It has a lockout so
you cannot shift directly from Fifth
to Reverse. When shif ting up or
down,makesureyoupushtheclutch
pedal down all the way, shift to the
next gear, and let the pedal up
gradually. When you are not shif ting,
do not rest your f oot on the clutch
pedal. This can cause your clutch to
wear out faster.Come to a full stop before you shift
into Reverse. You can damage the
transmission by trying to shift into
Reverse with the vehicle moving.
Push down the clutch pedal, and
pause f or a f ew seconds bef ore
shif ting into Reverse, or shif t into
one of the f orward gears f or a
moment. This stops the gears so
they won’t ‘‘grind.’’
When slowing down, you can get
extra braking f rom the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes f rom
overheating while going down a
steep hill. Bef ore downshif ting,
make sure engine speed will not go
into the tachometer’s red zone in the
lower gear.

Rapid slowing or speeding-up
can cause loss of control on
slippery surfaces. If you crash,
you can be injured.
Use extra care when driving on
slippery surfaces.

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.

discussed below.If the automatic transmission shifts

page ). When climbing hills, closely watch

vehicle misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over. Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
If you have an automatic
transmission, use the Over drive
(O/D) mode when towing a trailer
on level roads. Turn of f the Over

If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
place by pressing on the accelerator,
as this can cause the automatic
transmission to overheat.

Taking Care of the Unexpected
T aking Care of t he Unexpect ed307

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.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
(climbing a long, steep hill on a
hot day with the A/C running, f or
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.
The pointer of your vehicle’s
temperature gauge should stay in
the midrange under most conditions.
Itmaygohigherif youaredrivingup
a long steep hill on a very hot day. If
it climbs to the red mark, you should
determine the reason.
Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f the heating and cooling
system and all other accessories.
Turn on the hazard warning
indicators.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.
Your vehicle can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indicationmaybethetemperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
In either case, you should take
immediate action. 1.

If Your Engine Overheats
T aking Care of t he Unexpect ed323
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your 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 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. 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.Start the engine and set the
temperature control dial to
maximum. 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 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. 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 .)
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.

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

removing the radiator cap.
