2001 Acura RL coolant level

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

Before Driving

Before you begin driving your Acura,
you should know what gasoline to use, and how to check the levels of
important fluids. You also need to
know how to properly store luggageor packages. The information in this
section will help you. If you plan to
add any accessories to your car,
please read the information in this section first. Break-in Period.............................. 168

Service Station Procedures

3. Insert it all the way back in its tube.

4. Remove the dipstick again and
check the level. It should be
between the upper and lower
marks.

If it is near or below the lower mark,
see Adding Oil on page 217 .
Engine Coolant Check

Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see Adding
Engine Coolant on page 221 for
information on adding the proper
coolant.
Refer to Owner Maintenance
Checks on page 215 for information
on checking other items in your
Acura.

Owner Maintenance Checks
You should check the following items at the specified intervals. If
you are unsure of how to perform any check, turn to the page given. Engine oil level — Check every
time you fill the fuel tank. See page 171.
Engine coolant level — Check the
radiator reserve tank every time
you fill the fuel tank. See page 172 .

Windshield washer fluid — Check the level in the reservoir monthly.
If weather conditions cause you to
use the washers frequently, check
the reservoir each time you stop
for fuel. See page 227 . Automatic transmission — Check
the fluid level monthly. See page
228.
Brakes — Check the fluid level
monthly. See page 230 . Tires — Check the tire pressure
monthly. Examine the tread for
wear and foreign objects. See page
245.

Lights — Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
turn signals, brake lights, and
license plate lights monthly. See

page 250.

Maintenance

Cooling System

Adding Engine Coolant
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system for leaks.
This coolant should always be a mixture of 50 percent antifreeze and
50 percent water. Never add straight
antifreeze or plain water.
Always use Honda All Season
Antifreeze/Coolant Type 2. This coolant is pre-mixed with 50 percent
antifreeze and 50 percent water. It
does not require any additional

mixing.

If it is not available, you may use
another major-brand non-silicate
coolant as a temporary replacement.
Make sure it is a high-quality coolant
recommended for aluminum engines.
However, continued use of any non-
Honda coolant can result in
corrosion, causing the cooling system to malfunction or fail. Have
the cooling system flushed and
refilled with Honda antifreeze/ coolant as soon as possible.
If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
1. Make sure the engine and radiator
are cool.

RESERVE TANK

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.

Cooling System

2. Turn the radiator rap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by pushing down and turning
counterclockwise. 4. The coolant level should be up to
the base of the filler neck. Add
coolant if it is low.

5. Put the radiator cap back on.

Tighten it fully.

6. Pour coolant into the reserve tank.

Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.

Do not add any rust inhibitors or
other additives to your car's coolingsystem. They may not be compatible
with the coolant or engine compo- nents.

11.Fill the reserve tank to the MAX
mark. Install the reserve tank cap.

12.Check the level in the radiator,

add coolant if needed.

13.Install the engine cover. First

tighten the two bolts on the front of the engine cover, then tighten
the three nuts on the engine cover.

14.Install the radiator cap, and

tighten it to the first stop.

15.Start the engine and let it run until

the radiator cooling fan comes on
at least twice. Then stop the
engine.

16.Remove the radiator cap. Pour

coolant into the. radiator up to the base of the filler neck and into the
reserve tank up to the MAX mark.

17.Start the engine and hold it at

1,500 rpm until the cooling fan comes on. Turn off the engine.
Check the coolant level in the
radiator and add coolant if needed.

18.Install the radiator cap, and

tighten it fully.

19.If necessary, fill the reserve tank

to the MAX mark. Install the
reserve tank cap.

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.
