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
