Hi
I have a Ford Focus 1.6TDCi 08 plate Mk2.5.
A couple of days ago the engine got rather warm, the dash sensor was reading about 90ºC - a little higher than normal but far from exessive as i turned off the engine a beeper went off and the display showed "High Engine Temperature". I cannot be sure if this was just after i turned off the engine or just before, literally was as i turned the key. I then switched on the ignition again and noted the fan did not kick in, started up and drove around for a while with low revs to cool the engine. The Alarm stopped pretty much immediatley and and has not recurred.
Upon returning home I located the coolant sensor (from the side of the engine) and shorted out the terminals, with the ingnition on and the engine running the fan did not kick in.
I had my OBDII reader attached which has two temperature read outs, one was clearly the sensor i was testing (displayed -40ºC unplugged and
140ºC shorted out) there was also anther temperature reading on the scanner which was reading around 40ºC.I read that this is possibly an engine bay temp sensor, but cannot locate it?
Can anyone advise if the fan should kick in when i short out the coolant sensor?
Can anyone advise where to find the engine bay temp sensor?
While I am here, cambelt due soon anything other than the belt _KIT_ i should be replacing? I will be changing the aux belt too.
All advice greatfully recieved
