Burst Coolant Hose
Driving along in my 3.9l RV8 kit car at the weekend one of the heater matrix takeoff hoses burst off the front cover. I assume the resultant pressure
pumped the water from the system. I have a emergency coolant light which came on (admittedly I didn't see it come on and it may have been on
for 5min but I doubt more) and I looked down at the temp gauge which read 100c. The emergency light comes on at 95c. I pulled over and switched off
immediately. I refitted the hose. I refilled the system with water from a local and it took 6 litres. Drove home and it didn't miss a beat.
I warmed the car up on the driveway the following day and it didn't miss and beat and sounded fine. It behaved as normal. I haven't
driven it yet. I might have got away with this but what should I be looking out for. Obviously I am worried about head gaskets and possibly worse.

I'd be inclined to carry out a compression test if you have the tester - might show you more about the internal engine health. Other than that
a service with filters would be my only other course of action - most engines will be OK for a short period without coolant in them, the oil
circulates a lot of heat around the engine.

You don't need to do anything other than keep an eye on coolant oils. If the head gaskets are damaged it might not show up for months,
likewise the other problem that sometimes occurrs piston ring problems.
If after some running you do have lingering doubts about the head gaskets your local MOT station can do a quick test by sniiffing the coolant header
tank with their exhaust gas tester.
A compression test or even a cylinder leakdown test won't reveal anything. For a head gasket to blow to the extent to show on a compression
test their would be other major symptoms.

Noted - I was kind of working with what I have at home! Agreed, if the head gaskets have issues it may not display for a while.

Not that worried if the gaskets are gone. If I had to take it to Land Rover to get it fixed then I'd be worried. It won't cost a lot to
change the gaskets and I can do it myself. Time I have, cash I don't. I am more concerned with things that will cost me a lot financially.

Although it doesn't sound as if there's any major cooking of components I would be inclined to replace the thermostat just in case....

Can the Thermostat be damaged by overheating?

Oh yes - ask me how I know.....
IIRC they use wax as a sensing medium and excess heat can solidify it = jammed shut or mal-functioning.
For what they cost....

If it was my car, I'd just carry on using it and be thankful you've dodged a bullet. For the temp gauge to be still reading 100*c you
must've still had water around the sender at that point.

If the thermostat is damaged the normal runnning temp goes up --- if no change to running temo there is; no damage to the stat.

Mine hit 110/115 degrees for about 10 mins on the motorway last summer after the coolant pipe came off - I had HGF shortly after and it now smokes
like a trooper when revved after sitting a while on tickover so guess some seals went somewhere along the way or there was piston ring damage - I
'll drive it until I can't suffer the embarrassment any more or until it fails completely and then take it apart to see if I can fix it
myself - if not, I'll source another engine and stick that in/get it set up again.
At worst, it's a couple of hundred quid plus some time (with some luck you'll get a decent replacement) - or increase the budget and get a
new crated unit. 
Sigs are uncool.
