Is it possible to repair a radiator leak on a Buick 2003 lasabre

NO! don't pour that crap in it,won't work. new radiator required if it's got a hole in it. compare prices below....if rust is in it,coolant flush/back flush required before new radiator installed. https://www.rockauto.com/en/catalog/buick,2003 ,lesabre,3.8l+v6,1410343,cooling+system,radiator,2172 https://www.autozone.com/cooling-heating-and-climate-control/radiator
