Engine Coolant
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1. Check the amount of coolant in the reserve
tank.
2. If the coolant level is below the MIN mark,
add the specified coolant until it reaches
the
MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2

NOTICE
If temperatures consistently below -22°F (-30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Consult a dealer for more
information.
If Acura antifreeze/coolant is not available, you may
use another major brand 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.
