Don't waste your time trying to plastic weld it with rod. It won't last. Permatex makes a patch kit that works on radiator plastics.
permatex epoxy putty for gas tanks ..and rads ,,,looks like a cigar
from a ,melted water bottle
Gorilla glue
I need to plastic weld a crack in it so I need to know what material it's made of to get the proper plastic rod.
