My coolant resevoir is low, puddles of coolant only on top of radiator on 1992 Honda Accord

There is NO signs of leakage anywhere lower than the radiator top

try repl rad cap to start with it may not be holding pressure anymore
I put new cap on . Could it be thermostat? Thanx
Top tank on radiator is cracked? Dry it off and WATCH it as pressure builds in the system. OH! The power of observation!
I will check this. Thanx
your honda has a plastic tank...tank meets the aluminium core at the edges...that part between the tank and core is known for leaking...replace radiator.
I will check this. Thanx
You're very welcome Mr Jim Malcolm.
