Engine Coolant

Diesel models
Specified coolant:
Honda All Season 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 first. If it is completely empty, also check the coolant level in the radiator. Add the engine coolant accordingly.

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.
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 aluminium 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.

Reserve Tank

  1. Make sure the engine and radiator are cool.
  2. Check the amount of coolant in the reserve tank.
    • 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.


  1. Make sure the engine and radiator are cool.
  2. Turn the radiator cap 1/8 turn anticlockwise and relieve any pressure in the coolant system.
  3. Push down and turn the radiator cap anticlockwise to remove it.
  4. The coolant level should be up to the base of the filler neck. Add coolant if it is low.
  5. Put the radiator cap back on, and tighten it fully.

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.
