Where exactly is the coolant drain plug and drain bolt. P. 241 doesn't help. I can't seem to find it.
right side, left side?

Also shall i use honda coolant?

 

don't know

 

The coolent doesnt matter....just be sure you dont get the red kind. Get the green kind. Your manual has some specifics on which kind...what to avoid...etc. I got Prestone.

 

The coolant drain plug should be on the bottom passenger side, or middle of the radiator. I'm not sure, but this is where Honda usually puts them from previous experience.

I personally like to use Honda Pre-mix because it contains distilled water. Though, you could buy distilled water from the grocery store, and mix 50/50 with your favorite type of coolant.

Don't use regular tap water because it contains lots of crap (chlorine and other minerals) which will eventually clog the radiator core. Consider this a cheap investment.
