2000 Acura RL radiator

Batter
y

If your car's battery is disconnected
or goes dead, the engine's computer
needs to "relearn" the idle control.
After replacing or recharging the battery:
1. Make sure the climate control sys- tem is off.
2. Start the engine and let it run until it warms up (the radiator cooling
fan comes on at least twice), and
let it idle for five more minutes.
Your audio system will also disable it-

self when the battery is disconnected

or goes dead. The next time you turn

on the radio you will see "Code" in

the frequency display. Use the Pre-
set buttons to enter the five-digit

code (see page 162 ).
Charging the battery with the cables
connected can seriously damage your
car's electronic controls. Detach the
battery cables before connecting the

battey' to a charger.

Ai
r Conditionin g Syste m

Your car's air conditioning is a sealed system. Any major maintenance,
such as recharging, should be done
by a qualified mechanic. You can do a couple of things to make sure the
air conditioning works efficiently.
Periodically check the engine's
radiator and air conditioning
condenser for leaves, insects, and dirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.

The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.
Run the air conditioning at least once
a week during the cold weather
months. Run it for at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the refrigerant.
If the air conditioning does not get as

cold as before, have your dealer

check the system. Recharge the
system with Refrigerant HFC-134a
(R-134a). (See Specifications on page 298.)

Whenever you have the air conditioning

system serviced, make sure the service

facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasing
refrigerant into the atmosphere can

damage the environment.

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 Emergenc y
Towin g on page 292).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page170). 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 to
add 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 cap
counterclockwise, 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 to
maximum (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
plai
n water. Remember to have
the cooling system drained and
refilled with the proper mixture as
soon as you can.
11. Put the radiator cap back
on
tightly. Run the engine and watch
the temperature gauge. If it goes
back t

o the red mark, the engine
needs repair. (See Emergenc y
Towin g o

n page 29
2.)
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.

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.
