Cooling System
1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counter- clockwise, without pressing downon 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. Addcoolant 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.

Cooling System

Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or engine components.
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 useGenuine Honda antifreeze/coolant.
Draining the coolant requires access
to the underside of the vehicle. Unless you have the tools and
knowledge, you should have this maintenance done by a skilled
mechanic. 1. Slide the heater temperature
control lever to maximum heat.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. Thecoolant will come out through the
hole in the splash cover.

the engine. Tighten it again whencoolant comes out in a steady
stream with no bubbles.
9. Refill the radiator to the base of the filler neck. Start the engineand let it run until it warms up (the
radiator cooling fan comes on at
least twice). 10. Turn off the engine. Check the
level in the radiator, add coolant if
needed. Install the radiator cap,
and tighten it fully.
11. Fill the reserve tank to the MAX mark. Install the reserve tank cap.

If Your Engine Overheats

The pointer of your vehicle's temperature gauge should stay in
the midrange under most conditions.It may go higher if you are driving up
a long steep hill on a very hot day. If
it climbs to the red mark, you shoulddetermine the reason.
Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine. Your vehicle 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 orspray 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 heating and cooling system 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, for 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.
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.
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.ProCarManuals.comMain Menu Table of Contents s t

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
