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.
