490 uu Maintenance Under the Hood u Engine Coolant
Maintenance Engine Coolant This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolan t level every time you refuel or you
charge the High Voltage battery. Check the re serve tank first. If it is completely
empty, also check the coolant level in the radiator. Add the engine coolant
accordingly.
1. Make sure the engine and radiator are
cool.
2. Check the amount of c oolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■ Reserve Tank 1 Engine Coolant NOTICE
Genuine Honda engine coolan t is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about −31°F (−35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Honda Clarity Plug-In Hybr id dealer for details.
If Honda antifreeze /coolant is not available, you may
use another major brand of 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 anti freeze/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.Reserve
