1996 Toyota Corolla 4 cyl Four Wheel Drive Manual

I put 50/50 coolant into radiator and coolant bottle ; coolant bottle and radiator (drips/leaks) out from under neath car just as air conditong water? Need maintenance ; car runs great no overheating ; no milky water in engine oil? But afraid to keep driving car as such; hoping busted hose or radiator problem; not engne problem ; problem seemed to start as cool weather at night and hot weather during day, using heater and air conditioning simultaneously ; both are working fine ;
