Its either going to be a gasket, a freeze plug, or a hose that is leaking. You were pretty vague on its location and the miles on your motor..

Either way, all the above are easy to fix if you have tools and a manual.

There is stuff you pour in the radiator called Bars Leaks. It is a powder. Use that brand specifically. Pour two tubes in. If it doesn't stop your leak, I'll eat my hat!

And you will most likely be replacing you heater core if you don't disconnect the lines from it. Most stop leak products have a tendency to clog the heater core and it usually has to be replaced. So if you do use a stop leak product, be sure to disconnect the hoses going to the heater core.

Also, that product will not stop a hose leak, and if it does it won't stop it for long.

If you use any of these products, you have to realize that you basically band-aiding the vehicle. It could run for years or for a few days before the problem reappears. Fix it right if you can

I've been using Bars Leaks on various vehicles for more than 20 years and it has never failed me...

I've had this same problem recently, and could not see exactly where it was coming from. It seemed to be coming from near the water pump and I suspected a leaking gasket (none of the hoses were leaking and the thermostat was not the problem). I had been putting off the repair, until now. My wife was driving yesterday when the Jeep started making sounds and water pouring out all over. I did not get to hear it, but have now removed the pump and it looks like it's done for. I am in the process of replacing it, hoping it's the problem and the leak will be gone too.

I also have an oil leak from the same area, possibly coming from around the timing chain cover gasket. While I'm this far into it, I am going to replace that as well, although removing the bolt for the pulley is kicking my #@*. Also considering replacing the front oil seal?
