Engine Coolant 4-cylinder models NOTICE You will need a more concentrated coolant if you
are driving in extremely cold temperature below
-31 °F (-35 °C). Consult your Acura dealer for details
about a suitable coolant mixture.
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 possible.
Do not add rust inhibitors or other additives to
your vehicle's coolant system. They may not be
compatible with the coolant or with the engine
components.
Engine CoolantThis 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.Specified coolant: Honda Long Life Antifreeze/Coolant Type 2

Maintenance
Radiator NOTICE 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.
6-cylinder models 1. Remove the radiator cap cover. All models 2. Make sure the engine and radiator are
cool.
3. Turn the radiator cap counterclockwise and
relieve any pressure in the coolant system.
Do not press the cap down when turning.
4. Push down and turn the radiator cap
counterclockwise to remove it.
5. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
6. Put the radiator cap back on, and tighten
it fully.
7. Pour coolant into the reserve tank until it
reaches the MA X mark. Put the cap back
on the reserve tank.
WARNING
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.

Handling the Unexpected
Last thing to do
Once the engine has cooled sufficiently, restart it and check the temperature
gauge.
If the temperature gauge needle has gone down, resume driving. If it has not
gone down, contact a dealer for repairs.
How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure
only. Have a dealer flush the system with proper
antifreeze as soon as possible.
Next thing to do
1. Check that the cooling fan is operating
and stop the engine once the temperature
gauge needle comes down.
If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks. If the coolant level in the reserve tank
is low, add coolant until it reaches the
MA X mark. If there is no coolant in the reserve tank,
check that the radiator is cool. Cover
the radiator cap with a heavy cloth and
open the cap. If necessary, add coolant
up to the base of the filler neck, and put
the cap back on.
