Cooling fan saying on

[666legin]

Hi Guys, I am new on here so please be gentle. I have a 2003 1.8 Diesel connect which is doing me proud and still going strong on 182,000 miles. At the start of this week the cooling fan is runing from the word go when you start the engine, even from cold in the morning.

Relays are OK
Dash temp is ok when I start from cold
New Stat fitting and working OK.

I think you are going to tell me it is the cylinder temperature sender but my problem is, where the bloody hell is it so I can order one to replace it.

Please please help

PS a picture of my van ( was an ex- Abnormal load escort van when I first had it)

PPS a link to my facebook so you can see that also fit out vans in my spare time.
