Default Boxer 55 plate hdi 2.0lt thermo switch location

Hi people,
can someone please tell me where is the thermo switch located? I have peter's pocket manual and it says it is located in the rad fan housing. but it's not there on my van!
i have searched high and low on the internet every thread says it in the housing. i thought i had a DW10 engine, but am not so sure now. did peugeot move the thermo switch at all ?

I'm having the normal over heating problem, fans are not working.
have changed the thermostat, and put a new rad fan in but still overheats. My mechanic put a bridging relay in the fuse box and the fans worked, so he said get a new relay, but still nothing. The fans are not kicking in at all, getting real fed up driving around with the heaters on full to keep the temp down as much as poss, but on hot days the temp gauge sits just under the red on the dash.

my mechanic seems to think my model doesn't have a switch and it comes direct from the ecu, which he now says i might have to possible replace or just put in a direct switch to turn fans on manually which i'd rather not do.
any help would be appreciated

Default Update

Just got back from a new mechanic,
thought i'd update for anyone who is searching and has similar problems.
My Van was registered in 2006, so the end of line to that model. It doesn't have a fan switch like other models, it just runs straight out of the ecu. anyone trying to locate the coolant sensor/switch its just behind the water inlet that holds the thermostat.

anyway. Had a sniff test done to see if the head was ok, all good there. is now booked in for a flush through to see if i have any blockages.

there is certainly something wrong with the water flow because the pipes and rad are all different temps. my mechanic said if the flush through comes back clear the next thing to try is a new water pump, which considering i have done 130,000 miles a new timing belt is due soon, just might have to get it done sooner rather than later.
