Will that flex seal stuff stop a slow leak on the tank of a radiator?

No. Google it. I looked this up awhile back when I had a pinhole leak. Ended up just replacing the radiator. Think it was about $120.

Maybe for a temporary fix. Certainly not permanently.

Good stuff. Highly recommend. Seals leaks and adds lubrication to the cooling system as well.

you'll be paying someone to change the heater core if you use that shite. Heater core change is way more costly than changing the radiator.

What kind of vehicle (year, make, model) are we talking about?

wrong. I usually don't recommend any fix it kind of crap to pour into a vehicle but that Barsleak is awesome and no it will not stop up a heater core. It actually comes in factory Corvettes since there is aluminum blocks and heads and the stuff keeps retarded leaks from happening.

Sounds like you are talking about the plastic reservoir... then yes.

If it's the actual radiator, on a Ranger, it's almost as cheap and easy to change it with a pick-n-pull one.

Is the leak on the radiator or the overflow tank?

The top of a plastic radiator get hotter than any part of the coolant system if there's air present aka a leak.

Less than 100 bucks for new radiator.

The stop leak may work for a while. Is the leak a pinhole from a rock or corrosion? How long until more corrosion leaks begin? How long until you are in the middle of no where and a large leak occurs, engine overheats, warps your cylinder head and leaves you on foot in 98 degree heat?
