Oil Check

For a proper oil level reading, the dipstick must be 
inserted with the flat side of the dipstick handle 
facing the oil fill cap.

The amount of oil consumed depends on how the 
vehicle is driven and the climatic 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 
new.

Cooling System

This coolant is premixed with 50% antifreeze and 50% water. Do not add any

Checking the Coolant

1

Cooling System

Genuine Acura engine coolant is a 50/50 mixture of 
antifreeze and water that can withstand freezing at 
temperatures as low as about -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-Acura coolant can result in 
corrosion, causing the cooling system to malfunction 
or fail. Have the cooling system flushed and refilled 
with Acura antifreeze/coolant as soon as possible.

Do not add rust inhibitors or other additives to your 
vehicle’s cooling system. They may not be compatible 
with the coolant or with the engine components.
