You need to explain more on where exactly the coolant is leaking. There are several possible reasons why your coolant is leaking. If it's from your main hoses that lead to and from the engine or radiator, you need to check the condition the hoses are in. If they're in a decent condition, it's not that. If it's leaking around where the hoses are connecting, it's probably not tight enough, or there is possibly a clog in your coolant line. Also get your radiator checked. If it's leaking into the passenger compartment, it's most likely the heater core.
