if shes got water then its a air lock problem...look for a bleed screw on the pipework..it will look like a plastic screw into the pipe with a flathead screwdriver top.......remove filler cap for water bottle...start car and top up water bottle right top top......undo this bleed screw....the trick is that if the waters bubbling out then leave it...you want there to be a continuous stream of water to emerge from this hole........you dont have to remove the screw completely...just enough for the air to escape......once you have a steady stream do the screw back up!!!!!!the problem is you have to expel the air to enable the system to function properly....dont for get to top up any coolant fluid lost in the bottle......*****WARNING***** try to do this when car is cold as where youre undoing the bleed screw if shes hot you have a good chance of scalding yourself so please be careful......good luck..............if you cannot locate the bleed screw look on www.fiatboo.co.uk all about fiats...you can post the question there as to where its located....
