I found this fix, on Alldata,TSB, when looking up the Radiator.
As you know the top radiator plastic nozzle will break off, over time, as well as the overflow tank connection, on the top of the radiator.
This fix, will enable you to get back on the road, without changing the entire Radiator.
Here are the part numbers

Part numbers
200-121-001 radiator extension nozzle
200-121-002 radiator connection to overflow tank

200-121-003 special glue Alldata says you need only one hour, for the glue to set, up and you're back on the road.

I'm not sure this "kit" is available any more from dealers. I bought one a long time ago. It worked, but not a forever fix. Eventually the "special glue" will soften and it will blow off. This could be a year. It could be a month.

After mine blew out several times, subsequently using different types of epoxy each time, it blew for about the 4th time, I happened upon a new, metal radiator at a shop that was too cheap to pass up. I put the old plastic rad aside, thinking I would eventually fix it and see if anyone wanted to buy it.

My thought was to drill small holes through the nozzle and broken part of the tank. Using a small pop rivit would give both a mechanical connection and the epoxy. I never got around to doing it and the old rad is still sitting in my basement.

I repaired mine using a pipe nipple and some epoxy. Worked good so far for 2 years.

it happened while my wife was driving, wondered why the little red light with the thermometer was blinking, but drove another 15-20miles before deciding to check it out and get towed...by that time the rad was cracked, time for a new one...
