well bro, not an expert with coolant but i wud say honda OEM coolant shud do quite well. see if u can get that one.
how do u plan on changing the coolant? when i did it, i used a very stupid method of doing it i.e. opening the clamp of hose pipe, starting the car for a few seconds to push the water out n refill the coolant.
however, just a day or two ago, i was lying under my car, working on something, n i think i saw a radiator discharge pipe at the bottom of the radiator. it was on the back of the radiator (the side facing engine) almost in front of the place where the engine meets the gearbox. a small plastic cap/cork sort of thing which can be screwed out to let the water out. try to do it this way. n rinse the radiator thoroughly before u pour in the new coolant. ratio of coolant n water is recommended to be kept at 50:50 but i like to keep coolant at 60: and water at 40: because u DO have to add water into the reserve tank from time to time n that way, the fluid gets too dilute if u dont put more coolant than water.
