2001 Acura RL coolant temperature

Gauges

Outside Temperature Indicator
This indicator displays the outside temperature in Fahrenheit in U.S.
models, and in Centigrade inCanadian models.
The temperature sensor is located in the front bumper. Therefore, the
temperature reading can be affected
by heat reflection from the road sur-
face, engine heat, and the exhaust
from the surrounding traffic. This can cause the temperature reading
not to be correct when your speed is
under 19 mph (30 km/h).
In certain weather conditions,
temperature readings near freezing (32°F, 0°C) could mean that ice is
forming on the road surface.
Temperature Gauge

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 near

the upper white mark. If it reaches
the red (Hot) mark, pull safely to the
side of the road. Turn to page 283 for

instructions and precautions on

checking the engine's cooling
system.
Fuel Gauge

This shows how much fuel you have. It is most accurate when the car 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 gauge stays at the same fuel level reading after you turn off the
ignition. When you add fuel, the
gauge slowly changes to the new
reading after you turn the ignitionswitch back ON (II).

Instruments and Controls

Cooling System
Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only use Honda All Season Antifreeze/Coolant Type 2. Use of any non-
Honda coolant or plain water can
result in corrosion and deposits in
the cooling system.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance done by a skilled mechanic.
1. Turn the ignition ON (II). Turn
the heater temperature control
dial to maximum heat (climate
control to 90°F/32°C). Turn off
the ignition. Open the hood. Make
sure the engine and radiator are
cool to the touch.

2. Remove the radiator cap.
3. Loosen the drain plug on the
bottom of the radiator. The
coolant will come out through the
hole in the splash cover.

If Your Engine Overheats
The pointer of your car's tempera- ture gauge should stay in the mid-
range under most conditions. It may
go higher if you are driving up a longsteep hill on a very hot day. If it
climbs to the red mark, you should

determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.
Your car can overheat for several
reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the climate control and all other accessories. Turn on the
hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turnoff the engine.
3. 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, forexample), 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.

Taking Care of the Unexpected

NOTICE

Steam and spray from an

overheated engine can

seriously scald you.

Do not open the hood if steam

is coming out.

If Your Engine Overheats
4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 296 ).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page172 ). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have toadd coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator capcounterclockwise, without pushing
down, to the first 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. 10.Start the engine and set the
temperature control dial tomaximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained andrefilled with the proper mixture assoon as you can.
11. 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 Emergency
Towing on page 296 .)
12.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.

Taking Care of the Unexpected
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.
