Freelander td4 sport 2004 running well no issues.Turned on ignition .temperature gauge went straight to hot and cooling fans came on .Started first turn of the key ,engine management light stayed on ,temperature gauge stayed at hot ,fans continued to operate ,and engine ran alittle rough.It seems like the hippo thinks it is overheating when in fact it is stone cold. I would guess a sensor problem but which one and where is it.Can anyone help?

If the CTS has become disconnected, you will get the symptoms you have so check the wiring too.

I can confirm that - my son's Rover 220 T series has difficulty starting and is almost impossible to start when it is cold - plus the fans come on as soon as you turn the ignition on. If you disconnect the CTS, the symptons are exactly the same. I got a CTS off a K Series hoping it was the same - however, it has the same electrical connector but is the wrong size to fit the 'socket'. But... If you plug it in and just leave it lying on the 'somewhere' - the engine starts perfectly. At least that's give us a firm diagnosis and we can get a T Series CTS shipped over from UK now.
 
Thanks for all your help .problem was wiring at sensor was broken.Dont really understand why ,does not appear to be any reason for it to break.It looked suspiciously like the work of a rodent ,not a clean break and lots of little pieces of plastic lying around .The wires were bare .Managed to join it up with some spare wire and some very small electrical joining blocks .All working perfect .Back on the road total parts bill 40p .Big thanks again for pointing me in the rite direction.
