HONDA S2000 2000 1.G Owners Manual

Engine Oil
The oil container may also display
the
API Certification seal. Make sure
it says
"For Gasoline Engines."
158 Maintenance
The SAE numbers tell you the oil's
viscosity or weight. Select the
oil for
your car according to this chart.
60
. 10 20
" ~ c" ' -c '
AnlbielltTertlperature
An oil with a viscosity of lOW-30 is
preferred for improved fuel economy
and year-round protection in your
Honda.
You may use a 5W-40 oil if
the temperature in your area goes
below oaF (
-20°C).
Synthetic Oil
You may use a synthetic motor oil if
it meets the same requirements
given for conventional motor
oil:
energy conserving, a service
classification of
SJ, and the proper
weight as shown on the chart. When
using synthetic
oil, you must follow
the
oil and filter change intervals
given
in the maintenance schedule.
Additives
Your Honda does not need any oil
additives. Purchasing additives for
the engine or transmission will not
increase your car's performance or
longevity.
It only increases the cost
of operating your car.

Changing the Oil and Filter
Always change the oil and filter
according to the time and distance
(miles/kilometers) recommenda­
tions
in the maintenance schedule.
The oil and filter collect contami­
nants that can damage your engine
if
they are not removed regularly.
Changing the
oil and filter requires
special tools and access from
underneath
the car. The car should
be raised on a service station-type
hydraulic lift for this service.
Unless
you have the knowledge and proper
equipment, you should have this
maintenance done by a skilled
mechanic.
1. Run the engine until it reaches
normal operating temperature,
then shut it off.
2. Remove the engine oil fill cap.
Remove the
oil drain bolt from the
bottom of
the engine. Drain the oil
into an appropriate container.

3. Remove the oil filter and let the
remaining
oil drain. A special
wrench (available from your
Honda dealer) is required to
remove the filter.
4. Install a new oil filter according to
instructions that come with it.

5. Put a new washer on the drain bolt,
then reinstall the drain bolt.
Tighten it to:
33 lbf.ft (45 N·m, 4.6 kgf·m)
6. Refill the engine with the recom­
mended
oil.
Engine oil change capacity
(including filter):
5.1 US qt (4.8 Q, 4.2 Imp qt)
7. Install the engine oil fill cap. Start
the engine. The oil pressure
indicator light should go out within
five seconds. If it does not, turn off
the engine and reinspect your
work.
8. Let the engine run for several
minutes and check the drain bolt
and
oil filter for leaks.
160 Maintenance
9. Turn off the engine, let it sit for
several minutes, then check the
oil
level. If necessary, add oil to bring
the level to the upper mark on the
dipstick.
NOTICE
Improper disposal of engine oil can be
harmful
to the environment. If you
change your own oil, please dispose
of
the used oil properly. Put it in a sealed
container and take it
to a recycling
center. Do not discard it
in a trash bin
or dump it on the ground.

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 Genuine Honda
Antifreeze/Coolant.
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.
Cooling System
If the reserve tank is completely
empty, you should also check the
coolant level
in the radiator.
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.
1. Make sure the engine and radiator
are cool.

2. Turn the radiator cap 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.
162 Maintenance
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 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 use
Genuine 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. Turn the ignition ON (II). Turn
the heater temperature control
dial fully clockwise.
Turn the
ignition off.
2. Open the hood. Make sure the
engine and radiator are cool to the
touch.
3. Remove the radiator cap.
Cooling System
4. Loosen the drain plug on the
bottom of the radiator. The
coolant will drain through the
splash guard. Remove the drain
bolt and washer from the engine
block.

6. When the coolant stops draining,
tighten the drain plug at
the
bottom of the radiator.
Apply non-hardening sealant to the
drain bolt threads, put a new
washer on the drain bolt, and
reinstall
the bolt in the engine
block. Tighten it securely.
Tightening torque:
61 lbf.ft (83 N·m I 8.5 kgf·m)
7. Mix the recommended antifreeze
with an equal amount of purified
or distilled water
in a clean
container.
The cooling system
capacity
is:
1.72 US gal (6.5 Q I 1.43 Imp gal)
8. Loosen the bleeder bolt on top of
the engine, and remove
the
bleeder cap near the engine oil fill
cap. Pour coolant into the radiator
up to the base of
the filler neck.
Tighten the bleeder bolt and
reinstall the bleeder cap when
coolant comes out in a steady
stream with no bubbles.

9. Start the engine and let it run for
about
30 seconds. Then turn off
the engine.

Maintenance

Check the level in the windshield
washer reservoir at least monthly
during normal usage. In bad weather,
when you use the washers often,
check the level every time you stop
for fuel.
The windshield washer reservoir is
located
in the rear of the engine
compartment on the passenger's side. Check
the reservoir's fluid level by
removing the cap and looking at the
level gauge attached to the cap.
Windshield Washers
Fill the reservoir with a good-quality
windshield washer fluid. This
increases the cleaning capability and
prevents freezing
in cold weather.
When you refill the reservoir, clean
the edges of
the windshield wiper
blades with windshield washer fluid
on a clean cloth. This will help to
condition
the blade edges.
NOTICE
Do not use engine antifreeze or a
vinegar/water solution
in the
windshield washer reservoir.
Antifreeze can damage your car's paint,
while a vinegar/water solution can
damage the windshield washer pump.
Use only commercially-available
windshield washer fluid.
