DCI 'Engine Overheating' Warning, then fine again

[bobby_the_one]

Received this vehicle at about 7:30 this morning at 7:40 the STOP light illuminated with the warning 'Engine Overheating'. (Its my girlfriends old car and she has never had any problems)

I pulled over, turned the engine off, waited 5 mins and then fired her up again. She ran fine for the next 10 miles, with temp just below half way./

When i got to work i checked:

Water Level - fine
Under the oil cap - fine

My question, what else should i check? The warning light obviously came on for a reason. Sensor to check maybe? Any advice?

Water pump may have broken up internally thus not pumping coolant around.

Or a dodgy sensor. Does it smell like its got red hot ?

No, everything seems normal? You may be right, it could be a sign that the water pump is on its way .. Thanks for your reply.
