What type of coolant for a 99 Honda shadow 750?

Just pick some up at your Honda dealer. You want the right product for the water pump.

Answer#2: You can use the pre-mix Honda or Spectro MC coolant which is a premium product that lowers temp. To save money buy Prestone anti freeze at Wal- Mart (the one that mixes with any color anti freeze). Then also buy a gallon distilled water and mix and you will have 2 gallons 50/50 for about $10.
