Engine High Temperature Warning
5 minutes into my drive home I realised the temperature gauge was at 12 o'clock, the red light on and the "High Temperature" message. A few seconds later the message disappeared and the gauge dropped instantly to normal 9 o'clock, and stayed there for the rest of the journey, about 15 minutes.
A blip? The initial signs of a failing thermostat? Any ideas?

My first thought would be an airlock following such an incident

I've just remembered there was a bang or pop seconds before I saw the warning. I assumed it was something falling out a tree onto the roof, but could it be connected?

When she is cool see what the coolant level looks like in the expansion tank - is it normal ?

A slight hiss and no sign of any coolant through the top (you can't see anything through the side where the min max is, which means there's nothing there or the plastic is too opaque to see if there is).

Like Trikey says, look at the bottom of the header tank, with the cap off. You will see some ‘fins’ at the bottom. The water should just be above the bottom of the fins. The bottom, NOT at the top of the fins.

Coolant level: clarification
Quote:
Tenesmus; you've indicated that your expansion tank is empty. You need to fill it to the MAX marker and urgently investigate the reason for the coolant loss. Begin by checking inside the 'V'. Simon

Thanks chaps. I haven't had a chance to do anything except top it up to just above the MIN (didn't take much) and put the container in the boot.
I'll be disappointed if it's the thermostat (assuming that's why you mentioned checking in the V), it's already been replaced twice.

I had one replaced in 2016, the next in 2020, now it'll be another. Fortunately they are pretty cheap.
