Engine Coolant  
Adding Engine Coolant  
Always use Honda Long-life Anti-  
freeze/Coolant Type 2. This coolant  
is pre-mixed with 50 percent  
antifreeze and 50 percent distilled  
water. Never add straight antifreeze  
or plain water.  
If the reserve tank is completely  
empty, you should also check the  
coolant level in the radiator.  
RESERVE TANK  
Removing the radiator cap  
while the engine is hot can  
cause the coolant to spray out,  
seriously scalding you.  
If Honda antifreeze/coolant is not  
available, you may use another  
major-brand non-silicate coolant as a  
temporary replacement. Make sure 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

radiator cool down before

4. The coolant level should be up to  
the base of the filler neck. Add  
coolant if it is low.  
6. Pour coolant into the reserve tank.  
Fill it halfway between the MAX  
and MIN marks. Put the cap back  
on the reserve tank.  
RADIATOR CAP  
Pour the coolant slowly and  
carefully so you do not spill any.  
Clean up any spill immediately; it  
could damage components in the  
engine compartment.  
Do not add any rust inhibitors or  
other additives to your vehicle’s  
cooling system. They may not be  
compatible with the coolant or  
engine components.  
5. Put the radiator cap back on, and  
tighten it fully.  
1. Make sure the engine and radiator  
are cool.  
2. Relieve any pressure in the cooling  
system by turning the radiator cap  
counterclockwise, without  
pressing down.  
3. Remove the radiator cap by  
pushing it down and turning it  
counterclockwise.
