uuMaintenance Under the Hood uEngine Coolant
Maintenance
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
■Reserve Tank
1Engine Coolant
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 a dealer for 
details.
If Honda 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-Acur a coolant can result in 
corrosion, causing the cooling 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. They may not be compatible 
with the coolant or with the engine components.
