NOTE (K24Z7 engine):
* Always use Honda Long Life Antifreeze/Coolant Type 2. 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. Do not add water.
* If the vehicle is regularly driven in very low temperatures (under -31 °F,-35 °C) a 60 % concentration of coolant should be used.
