uuMaintenance Under the HooduEngine Coolant
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.
2Engine Compartment Covers P. 233
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.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2■
Reserve Tank
1Engine Coolant
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

Manual Transmission Fluid
Specified fluid: Acura Manual Transmission Fluid (MTF)
1Manual Transmission Fluid
If Acura MTF is not available, you may use the API
certificated SAE 0W-20 or 5W-20 viscosity motor oil
as a temporary measure.
Replace with MTF as soon as possible. Motor oil does
not contain the proper additives for the transmission
and continued use can cause decreased shifting
performance and lead to transmission damage.
