NOTE:

Use Honda Long Life Antifreeze/Coolant Type 2, and if necessary add Honda Extreme Cold Weather Antifreeze/Coolant Type 2 (concentrate). Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail.

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 °F ( -30 °C)), a 60 % concentration of coolant should be used.

Operation	Vehicle Usage (Desired Mixture)	Current Mixture	Coolant Drain	Add Amount of Honda Extreme Cold Weather Antifreeze/Coolant Type 2 (100 % concentrate)	Then add Honda Long Life Antifreeze/Coolant Type 2 (50/50)
Coolant Change	Normal Area (50/50)	50/50 60/40 unknown	Drain radiator, engine block, and reservoir	None	Top off the cooling system
	Very Cold Area (60/40)	50/50 unknown	Drain radiator, engine block, and reservoir	About 1.3 L (44 fl oz)
	Very Cold Area (60/40)	60/40	Drain radiator, engine block, and reservoir	About 1.2 L (41 fl oz)
Engine Overhaul	Normal Area (50/50)	-	-	None
Engine Overhaul	Very Cold Area (60/40)	-	-	About 1.2 L (41 fl oz)
Coolant Winterizing	Very Cold Area (60/40)	50/50	Drain about 2.0 L (68 fl oz) from radiator	About 1.2 L (41 fl oz)
Coolant Winterizing	Very Cold Area (60/40)	unknown*	Drain radiator, engine block, and reservoir	About 1.2 L (41 fl oz)

*: When you want to winterize the coolant with the minimum amount of coolant change but the current coolant concentration in the vehicle is unknown, you must drain all coolant from the cooling system.
