Honda Civic: Engine Coolant - Maintenance Under the Hood - Maintenance - Honda Civic Owners ManualHonda Civic: Engine Coolant

Specified coolant: Honda Long Life Antifreeze/Coolant Type 2

This 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.

NOTICE
2.4 ℓ engine models
You will need a more concentrated coolant if you are driving in extremely cold temperature below −31°F (−35°C). Consult your Honda dealer for details about a suitable coolant mixture.

All models
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.
