facing the oil fill cap.
The amount of oil consum ed depends on how the
vehicle is driven and the cl imatic and road conditions
encountered. The rate of oil consumption can be up
to 1.05 US quart (1 liter) per 625 miles (1000 km).
Consumption is likely to be higher when the engine is

■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 coo ling 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.
