Over heating issues disco 2
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.

@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.

Thanks for the info it was a good read but I am tight on money at the moment and am trying to cover a variety of little issues at the moment down the road I will be sure to make these necessary adjustments
