Ahh. When that was done, I wonder whether the cooling system was filled and bled according to the specific MG Rover procedure. If not, you may well have some air remaining which is known to cause level variations at the very least.

You assume but of course you don't know and neither do I so the sensible assumption is that they didn't. You can rectify that now. Drain your cooling system and refill and bleed it according to the MGR procedure. I can post it for you if you like.

That tells us that you have a fault. The KV6 should run below 100 degrees C. I suggest that you perform the 'demist test' immediately. With the engine running from cold, press the 'windscreen demist' button on the air con./heater control panel. Now get out of the car and walk to the radiator grille. Is the fan running continuously?

Whilst you're there, can you see a rectangular silver resistor on the fan shrouding at about the two o'clock position?

Charlie, you must take action immediately on this. Your engine is getting too hot. Please report back.

So should your first answer, Simon, say YES it's possible.--( Heat soak condition. )

Thank you for raising this point Jon. Charlie didn't ask if it was "possible", he said "should the fan keep going", questioning whether this is to be expected on a properly functioning engine.
The clue is actually in my first response:

You'll see from the RAVE chart posted by T-Cut that Charlie's coolant temperature had apparently increased beyond 112 degrees (the trigger point for maximum fan speed). That is a clear sign of overheating. The cause of this is currently under investigation.

So the answer to Charlie's original question ...

... remains no. The engine should not have reached such a high temperature in the first place. There is a fault.

I hope that makes more sense but please get back to me if it's still not clear.

Sorry if this is a silly question but on my kv6, and with this very hot weather should the fan keep going after the engine has been switched off?....................

If you have a look at data provided by T-Cut it is what the system is designed to do. ;)
