Hoping diagnoses nothing, guessing it is a thermostat diagnoses nothing. The dash thermometer does nothing and never did by design.
5 minutes to boil needs compression testing to find if head gasket is bad. Instant 'boiling' after start may not be actual boiling but exhaust gas getting into the coolant. An uncapped coolant reservoir can tell that.

Good.
Not telling to do it, but if I were you, would totally eliminate the thermostat by hooking a hose directly from the lower radiator outlet to the coolant pump suction and engine outlet to radiator inlet discarding the bypass hose.
If your new thermostat disappointingly behaves bad when installed, come back.

Dunno if anyone mentioned it but if you're dropping the money for new T-stat now is the time to do the Extinct tstat mod. Its where you're going to end up anyways so may as well be now

@Maxwell_land A good compression test only eliminates bit head gasket failures, small crack related failures that open only after warmth will pass a lot of the time but still over-pressure your cooling systems.

My head gasket failure would have passed a compression fine, cold. But I never over heated, just over pressured.
