ce

Cooling System

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. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve

tank.

u

If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.

Cooling System

NOTICE

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 a 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.

WARNING

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.
