Why would water be leaking from the engine of a Honda Civic?

check your water pump..it might be bad it could be your water pump, or it might be a leak in your radiator. check those first. If the water is green or orange, it is probably coolant, check water pump seal, radiator, radiator hoses, and maybe the heater core. If the water is clear and comes out when the A/C is on, it's condensation from the air conditioning. A/C condensation is perfectly normal.
