FWIW I shredded a water pump belt on the highway last year. 90F+ day with AC running. By the time I noticed & pulled over safely I'd hit 260F. My engine is fine, no head gasket issues, and I'm turbocharged too.

A proper coolant flush was called for as the boiling stirred up deposits. One might even call it a therapeutic overheat.
