What glue for the rad stopped the leak there Tom?
I know all too well it is not a permanent repair, but didn't have time to buy one, parts stores all closed, so had to go go go go
But Loctite Epoxy Plastic bonder . 3450 PSI rating
For PVC, Polycarbonates, Acrylics, ABS, FRP, and other plastics.
Cleaned it well with Jax Wax engine / tire etc cleaner, washed it down.
