When the housing was replaced,was a new stat fitted as the new part does not come with new stat.There is a coolant temp sensor but it is the same unit that provides temp info to the engine management system(unlikely to be faulty).The hexagonal brass temp sensor hooked up next to battery is an official modification by Ford to bring the cooling fans on under extreme under bonnet temps,so nothing to worry about.hth

If it,s an auto box,then I think this would make it a 1600,not a 2 litre?

Just a bit of an update as this issue is doing my head in,

I just started the car up and let it warm up, as the gauge was slowly moving up it the engine revs very slightly dipped and the gauge drop back to cold then a few seconds later continued to move up to the central position.

All of which was done with the car stationary.

My instincts are screaming that its a sticky thermostat but iv just had a new one fitted, has anyone else had similar problems with a focus or any advice would be really much appreiciated.

Im driving to eurpoe in a few weeks and id really like to get to the bottom of this before then.

Also the pipe into the bottom of the radiator was stone cold !!!

Thanks in advance

As far as i am aware they are all genuine parts and i think its been bled properly.

Im going to call the garage i got it done at tomorrow and get it back in, or do you think i should just take it to ford ??

Iv had plenty of cars in my time that overheat but this is just so random and annoying.

Thanks for your help
