coolant temperature HONDA CR-V 2002 RD4-RD7 / 2.G Owners Manual

This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise
from the bottom white mark to about
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to the
upper white zone. If it reaches the
red (Hot) mark, pull saf ely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system.
The temperature sensor is located in
the f ront bumper. Theref ore, the
temperature reading can be af f ected
by heat ref lection f rom the road sur-
f ace, engine heat, and the exhaust
f rom the surrounding traf f ic. This
can cause the temperature reading
not to be correct when your speed is
under 19 mph (30 km/h).
This shows how much f uel you have.
It is most accurate when the vehicle
is on level ground. It may show
slightly more or less than the actual
amount when you are driving on
curvy or hilly roads.
The needle returns to the bottom
after you turn off the ignition. The
gauge shows the f uel level reading
immediately af ter you turn the
ignition switch back ON (II).
When the outside temperature goes
down below 37°F (3°C) the f irst
time, the temperature reading blinks
about ten times to show you the
outside temperature is low. In certain
weather conditions, temperature
readings near f reezing 32°F (0°C)
couldmeanthaticeisformingonthe

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

Turn the temperature control dial
all the way to the lef t.

Select and Fresh Air mode.
Set the f an to the desired speed.
The outside air intakes f or the
heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.
It is best to leave the system in Fresh
Air mode under almost all conditions.
Keeping the system in Recirculation
mode, particularly with the A/C of f ,
can cause the windows to fog up.
Switch to Recirculation mode when
you are driving through smoky or
dusty conditions, then switch back to
Fresh Air mode when the condition
clears. This section covers how to set up the
system controls f or ventilation,
heating, cooling, dehumidif ying, and
def rosting.
The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
The f low-through ventilation system
draws in outside air, circulates it
through the interior, then exhausts it
through vents near the tailgate.1.

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.

it climbs to the red mark, you should
determine the reason.

Wait until you see no more signs

Your vehicle can overheat for several

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.
