Maintenance
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.
1.Remove the right-side engine compartment
cover.

2.Check the amount of coolant in the reserve
tank.
3.If the coolant level is below the MIN mark,
add the specified coolant until it reaches
the MAX mark.
4.Inspect the cooling system for leaks.

NOTICEYou 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 cooling system. They may not be compatible
with the coolant or with the engine components.4-cylinder models

Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.
uIf 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.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
uIf 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.
■
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.
1How 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.

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.
