I spoke with an instructor of mine who has worked with Honda for many years. Honda Genuine coolant is highly recommended. Regular Prestone type anti-freeze will work fine but Honda Genuine coolant will last longer and will not wear away at seals nearly as much as anything else.

Honda Genuine coolant is different than your normal anti-freeze. You will notice the color is a much darker green. It even smells different. It is much safer for aluminum components. It does not contain the silicates that most others do. These silicates act as an abrasive on the seals.

I know it's expensive ($11 a gallon, pre-mixed) but it's worth it. Every one to two years drain and fill the radiator and overflow. One gallon should be enough for this. With this basic maintenance you should have no problems at all with the cooling system.
