Engine Coolant  
1Engine Coolant  
Specified coolant: Honda All Season Antifreeze/Coolant Type 2  
Removing the reserve tank cap while the  
engine is hot can cause the coolant to spray  
out, seriously scalding you.  
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. Add the engine coolant accordingly.  
Always let the engine and radiator cool  
down before removing the reserve tank

2. Check the amount of coolant in the reserve  
u If the coolant level is below the MIN  
mark, add the specified coolant until it  
reaches the MAX mark.  
If temperatures consistently below -30°C are  
expected, the coolant mixture should be changed to  
a higher concentration. Consult your Honda dealer  
for details about a suitable coolant mixture.  
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 aluminium 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  
3. Inspect the cooling system for leaks.  
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.
