Cooling System
Adding Engine Coolant

If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line. Inspect the cooling system for leaks.
This coolant should always be a mixture of 50 percent antifreeze and50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
Antifreeze/Coolant. If it 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.
However, continued use of any non-
Honda coolant can result in
corrosion, causing the coolingsystem to malfunction or fail. Have
the cooling system flushed and refilled with Honda antifreeze/
coolant as soon as possible. If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.

Maintenance

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.

Cooling System

1. Make sure the engine and radiator
are cool.
2. Turn the radiator cap counter- clockwise, without pressing downon it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by pushing down and turning
counterclockwise.
4. The coolant level should be up to
the base of the filler neck. Addcoolant if it is low.
5. Put the radiator cap back on. Tighten it fully.
6. Pour coolant into the reserve tank. Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
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.

Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the timeand distance recommendations in
the maintenance schedule. Only use Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to the underside of the vehicle. Unless you have the tools and
knowledge, you should have this maintenance done by a skilled
mechanic.
1. Turn the ignition ON (II). Turn
the heater temperature controldial fully clockwise. Turn the
ignition off.
Open the hood. Make sure the
engine and radiator are cool to the

touch.
