uuMaintenance Under the HooduEngine Coolant  
Engine Coolant  
1Engine Coolant  
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2  
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-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  
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.  
Reserve Tank  
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.  
1. Check the amount of coolant in the reserve  
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.

1. Make sure the engine and radiator are  
Removing the radiator cap while the  
engine is hot can cause the coolant to spray  
out, seriously scalding you.  
Radiator Cap  
2. Turn the radiator cap counterclockwise to  
relieve any pressure in the cooling system.  
Do not push the cap down when turning.  
3. Push down and turn the radiator cap  
counterclockwise to remove it.  
Always let the engine and radiator cool  
down before removing the radiator cap.  
4. The coolant level should be up to the base  
of the filler neck. Add coolant if it is low.  
5. Put the radiator cap back on, and tighten it  
6. Pour coolant into the reserve tank until it  
reaches the MAX mark. Put the cap back  
on the reserve tank.  
Pour the fluid slowly and carefully so you do not spill  
any. Clean up any spills immediately; they can  
damage components in the engine compartment.
