Replace the radiator. An aftermarket radiator can be had for less than $140. I wouldn’t cut the hoses, you can disconnect them from the radiator and connect them together with a piece of steel tubing to get by for a while.
Plastic side tank radiators don’t last forever and replacing it now may save you from an inconvenience in the future. It may be due to the local enviroment but recently I’ve replaced a few 2004-2006 Toyota radiators with cracked plastic tanks, even $500. radiators don’t last forever.
