Radiator problem

Hi accord lovers I need help i have crack in under the dadiator cap and I want to get it fix temporary till i buy new radiator and it is plastic radiator any idea to do that and I'm thankfull for ur help.

The problem with using any off the counter plastic repair kits is that the thermal expansion factor of the repair kit must match the source material exactly or the patch will pop off. On top of that, the radiator is under pressure so any flexible repair material will probably leak. You could leave the radiator cap loose and drive carefully until you get a new one.
