Engine Coolant
This coolant is premixed with 50% an tifreeze 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.
3. Inspect the cooling system for leaks.
Specified coolant: Ho nda Long Life Antifreeze/Coolant Type 2

1Engine Coolant
NOTICE
Genuine Honda engine coolan t 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 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-Honda coolant can result 
in corrosion, causing the cooling system to 
malfunction or fail. Have  the cooling system flushed 
and refilled with  Honda antifreeze/coolant as soon as 
possible.
Do not add rust inhibitors  or other additives to your 
vehicle’s cooling system. Th ey may not be compatible 
with the coolant or with the engine components.
3WARNING
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.
