6.2, closed cooling?

Have you used an IR temp sensor to take reading of spots on the engine and exhaust to confirm its hot and not a faulty alarm?

Clogged heat exchanger (If there is closed cooling). Did you burn out an impeller? IF so, did you recover all the blades?

Try changing the alarm sender.

You said running at 180, so i assume your gauge sender is working. Same water stream, should read the same temp. Sounds like the sender is bad.
