it should be in the owner's manual, it being a DIY... the manual should also warn, that it may be opened only with caution, and when engine is not hot. as in, first thing in the morning, if i may suggest.
some autorithies say that because today's engine blocks are metal alloys, coolant is the prefered liquid. it has anti-oxidation additives.
but i confess, i also used to use plain water.
the only water drip allowed, sir, are from the condensed water around the aircon's tubings, and from the evaporator drain under the dashboard (it has a plastic tubing draining out under the car or engine bay.) . dripping from the radiator or overflow reservoir, is not a good sign.
good luck.
