■Checking the Coolant
1Cooling System
NOTICE
Genuine Acura engine cool ant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout -31°F (-35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Acura NSX dealer for details.
If Acura antifreeze/coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Ac ura coolant can result in
corrosion, causing the cooling system to malfunction
or fail. Have the cooling system flushed and refilled
with Acura antifreeze/cool ant as soon as possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. Th ey may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the reserve tank 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 reserve tank
cap.

uuCleaning uExterior Care
Maintenance
If you get gasoline, oil, engine coolant, or battery fluid on resi n coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lo se their luster or appear burn ished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.

Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
turn the power system off once the
temperature gauge pointer goes down.
u If the cooling fan is not operating,
immediately turn the power system off.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
2 Checking the Coolant P. 396
uIf the coolant level in the reserve tank is
low, or no coolant in the tank, check that
the radiator is cool. Cover the reserve
tank cap with a heavy cloth and open the
cap. Add coolant until it reaches the
MAX mark, and put the cap back on.
■Last thing to do
Once the engine has cooled sufficiently, turn the power system on and check the
temperature gauge. If the temperature gauge pointer has gone down, resume
driving. If it has not gone down, contact an authorized Acura NSX dealer for repairs.
