Hi again Guys,Well I finally got a new C/H Temp Sensor on eBay for £25 (New). I have now got the Haynes w/s Manual for my 2006 TDCi Mondeo also, however the manual was of little help on this (typical) Anyway, I got stuck-in and here's the route I took should this be useful for future reference to anyone suffering the same problems I had. So here goes,

Firstly, I removed the cover over the pump pulley on the right hand side of the Cylinder Head which revealed the location of the sensor which was in a very tight working area. The manual said I needed to remove this pully to facilitate changing the sensor, yeh right However this pulley had convenient slots in it so you could pass a socket drive through to access the sensor.

Next, came the problem of the wire attached preventing the use of a normal socket wrench (a spanner was of no use either as the sensor is recessed) So I found an old 15mm socket and cut a slot to about 3/4 of the way down with a thin disc cutter to allow the wire to exit the side of the socket. I next had to stab the starter a few times to get the window slot in the pulley in just the right position, after disconnecting the plug connector I then carefully turned the sensor about a quarter of a turn at a time until the cable started to jam against the c/h, then by releasing and re-positioning the socket I was able to free and finally remove the sensor.

Finally, I fitted the new sensor in position and did the reverse procedure to tighten it, (It doesn't need much torque, about 6ft/lb only is recommended). I reconnected the plug and started the engine and voila, the engine warning light went out. So I took it for a test drive and found no further problems. I also had full turbo power again (no more limp mode) . Job done and all in under one hour !

I hope this saga was not too boring, but I thought the procedure will be of some use to other FOC members.
My best regards to all,
Bob.

Hi Dan62,
Thanks for your response, I had a good look at this today and trace the cable leading to the Temp Sensor and it appears to be behind a pulley and as I see it, it looks like I will have to remove this pulley to get at the sensor I just can't see any other way (assuming I'm looking in the right place, ha, ha). Maybe the Ford parts dept. might confirm it's position etc. I will give them a call tomorrow and hope they'll talk to me
I heard somewhere that it needs a special spanner as it is recessed, do you know if that is correct also would you know of a link I can go to where I could see a diagram of it in situ ?
Very many thanks for your help,
Bob.

Hi Jeebowhite,
Thanks for the tip, I will check the temp of the radiator when the fan stops, as I think if the thermostat was actually stuck the engine would start boiling and gushing steam (only my inexperienced guessing coming into play here lol). The breakdown guy plugged a meter into the car which immediately gave this code P1288 which points directly to the C/head stat. I will let you know my findings after tonight.
Thanks for your response and advice ,
Best regards,
Bob.
