it all depends on how big the hole is. but i would not suggest ever using a "leak stopper" unless it is an absoulue emergency, they always cause problems down the road which can get very expensive. I agree with that fella above...If you MUST use something use a table spoon of black pepper. This stuff is a miracle worker and its not AS detrimental to the other components of the cooling system. My grandaddy showed me this "indian trick" on an old Dodge car with a crack in the water pump....It ran fine for several years answer i agree with not using stop leak it makes the problem worse down the road the black pepper solution i have used many times in engines fro 4 cylanders all the way up to 450 horsepower truck engines most laugh but it is fool proof and will come out of engine when u dump radiator other than that, replace heater core they are not expensive

You have to remove the entire dash to get to the heater core. It is a job that makes even the most experienced mechanics cringe. What is the problem. If it is not putting out warm air you can back flush it. If it is leaking put some Alumaseal in your radiator. It won't clog up your cooling system, but will stop a leak in the heater core. I think it's a couple of bucks at your auto parts store. Don't put any of that Bar's leaks in the system. It WILL clog up your radiator. Stay away from the liquid gooey kind of leak fixer. Use only Alumaeal. After putting it in let your car fully heat up and turn on the heater maximum to get it to work.

Yes, the leak definitely sounds like a leaking heater core. Sometimes they are easy to replace, and sometimes they are difficult. You can try some radiator stop leak in the radiator but most of the time they have to be replaced. If you do it yourself, get a good repair manual from an auto parts store. It will have the instructions on how to replace it.

If it is just plain water, then you have either a leaking windshield or more than likely a stopped up A/C drain line. Look under the car passenger side and find the drain line and unclog it. If, on the other hand you have coolant leaking, then you have a leaking heater core, which must be replaced. Taste and smell the liquid. If it smells and taste sweet it is coolant and not just water.
