Is it possible for a loose cap on the coolant overflow tank to cause the car to overheat? Also i noticed underneath the car coolant collects on the bottom of the radiator... could the radiator leak coolant?

  It is not vary likely that a loose coolant cap on an unpressurized coolant overflow tank will cause the engine to overheat as long as the coolant level is where is should be. Yes, a radiator leak can cause coolant to collect at the bottom of the radiator. I would recommend you have the cooling system on your 1997 Honda Civic pressure tested to be sure where the coolant leak is coming from before replacing any parts.
