Can Fiero radiator be fixed with sealant fluids?

[Timantt1]

I have -88 Fiero GT, today I saw a wet spot under the car, and I found out that the radiator is leaking from the left side of the vehicle.

I suppose I need a new radiator.

Anyway, they sell these "stop-leak radiator sealant" fluids. Have anyone tried them to Fiero, and are they even safe to use due the unusual cooling system.

Just want to know if it's safe to test any of those sealants for temporary repair.

No, Stop leak will mess up the car. It will seal the leak, But also clog radiator core tubes and heater core tubes. It's easier and cheaper to pull the radiator out and have it cleaned and repaired at a shop. They will acid dip it, repair the crack and repaint it. My original one cost about $50 to do it.
