1998 HONDA PRELUDE radiator

Air Conditioning System
Your vehicle's air conditioning is a sealed system. Any major mainte-
nance, 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 255.)

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.

Replacing a Parking Light Bulb
1. Open the hood. The front parking light is next to the headlight bulb.
If you need to change a bulb on
the passenger's side, remove the radiator reserve tank by pulling it
out of its holder.
2. Remove the socket from theheadlight assembly by turning itone-quarter turn counterclockwise. 3. Pull the bulb straight out of its

socket.

Push the new bulb straight into
the socket until it bottoms.
4. Insert the socket back into the headlight assembly. Turn itclockwise to lock it in place.
5. Turn on the parking lights to make sure the new bulb works.
6. (Passenger's side) Reinstall the radiator reserve tank.

If Your Engine Overheats

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 Towing on
page 250).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page 124). 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 pushingdown, 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 comesoff. 10. Start the engine and set the
temperature control lever to
maximum. 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 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 to the red mark, the engine
needs repair. (See Towing on
page 250.)
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.ProCarManuals.comMain Menu Table of Contents s t
