Normalised or not the gauge will still go into the red well before the engine seizes up and you will still have time to pull up and shut the engine down.
You may be unlucky and bugger the head gasket/gaskets but it won't seize the engine if you keep an eye on the gauge and pull up in time.

Warranty and consumer law are different things. A hose which won't last the warranty period is not fit for purpose.

I lost coolant in an older vehicle and i was watching the gauge and it definitely did not go into the red zone. Nor the second time when the first repair failed. From memory it pinged, then conked, and i pulled over. Amazingly perhaps there was no damage. Bodgy repaired the leak both times, refilled with water and drove fine. Lucky.

If the coolant sensor is in coolant the gauge will go into the red zone with increasing temp - however if coolant is lost or is low so the sensor is not in the coolant the gauge will continue to read normal despite increasing temps.

Not all i know on a d2 if you lose your coolant the gauge will drop and read cold in the blue[bighmmm]
The sensor gets it`s reading from the coolant so if there isn`t any coolant there is zero reading [wink11]

Not always, I’ve known several that dropped coolant, stayed in the normal zone and that was the end of the head & gasket.

opposite experience. the gauge shows hot when its lost coolant and its been hot

The simple solution to this dodgy temp gauge issue is to install an audible low coolant alarm which will prevent any damage happening due to a loss of coolant event.
I hear that some of the new cars now have these fitted as standard equipment.

not sure about new cars but my 02 commodore has a low coolant alarm as standard.

One of my brothers ran the Uluru park for quite a few years.

The numerous 70 series they used had both a big red light mounted on the dash, and an audible, low coolant alarm.

The engines in the vehicles were still destroyed regularly from lack of coolant....[bighmmm]
