• Honda Long Life Antifreeze/Coolant Type 2 is a mixture of 50 % antifreeze and 50 % water.

  Honda Extreme Cold Weather Antifreeze/Coolant Type 2 is a 100 % concentration coolant. Do not add water to either coolant.

• If the vehicle is regularly driven in very low temperatures (below -22 ºF (-30 ºC) ), a 60 % concentration of coolant should be used.
