While it's possible that the heater core is leaking, it's probably a hose. Are you certain that it's coolant? When the AC compressor is on, either during the summer or when the defroster is running, you will get condensation dripping from that area. it is a large coolant leak. just not sure what line it is coming from.. there is alot of lines in the leak area. can the core be taken out under the dash or does the dash have to be removed. thanks for the help

Why is your coolant leaking?

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.
