Ok The Missus has a Fiat Bravo 1.4s 96. Without warning started over heating, with out cooling fan cutting in.
Water in the expansion tank luke warm, lots of pressure, radiator cold , the breather valve off the left hand side of the water pump when unscrewed slowly only lets out steam. The waterpump was replaced at 44,000 miles and the car has 47,000 but i'm sure these symptoms point towards a lack of circulation any ideas ?:bang:

Least the thermostat is a pretty minor job and you can always take it off, test it then put it back if it's working.

This is true , i guess to test it just wack it in hot water ?

Exactly, drop it in a pan and bring it to the boil. Watch for it opening around 80ish degrees. Nnot sure of exact temp but that may be stamped on it somewhere.

If it's failed closed then you'll see straight away once its off the car.

If you have steam on one side and cold water at the other then it certainly is a circulation problem.:)
I'd give the system another drain down and refill to get rid of any air in the system
THERMOSTAT
Feel the pipes either side of the thermostat and see if you can feel the the sudden surge of hot water when the thermostat opens a few mins after starting from cold. No need to take the thing out then, you can feel whether it opens

another bit of advice

dont use water in any fiat,

flush system totally when sorted and use the correct spec. antifreeze
otherwise there could be issues down the road
