Still nothing...i wired the radiator fan direct to the battery and it works fine...dunno what to do now but off to buy a relay etc so i can wire the fan direct and at least cool the car so i can use it...

Any other suggestions greatly appreciated untill i solve this it will have to stay on switch/relay for now:(

i put a direct 12v to pin 3 and attempted the test again.
Still the same nothing what so ever except lhs/ has a unit with 2 pipes and some electrical connections at 1 end underneath the radiator filler bottle this seemed to energise when volts applied to pin 3 and maybe had a clicking although it sound like wires arcing.

Damn its getting more complicated

ok definetly didnt blow any fuses as i was careful bridging and 100% sure never touched the live

All fuses are ok i just checked and whilst there checked the rest with my meter just for sake of it..So i have no power to my fans and all fuses are ok and confirmed 0volts at pin 3 with ignition on or off.

Thanks for you reply
Ok ive just finished testing the fuse/relay compartment out as per that post and diagram and the following is what i get.

Nothing happens when i bridge the pins.

Just to comfirm im doing this without the keys in ignition.
Ive also tested with meter and pin 3 has no volts

All fuses in this compartment seem fine.

Any suggestions on what fuse if any runs that and where its located or what to do next would be great

Firstly hello all and sorry if ive posted a double topic but i have looked and i did notice there was a thread on how to replace the radiator sensor.
I purchased this car a couple of days ago.
All seemed well untill last night when i could smell an overheating smell.This morning when i went out in it i noticed after a while the engine started to overheat i.e into the red.
After letting it cool down then finally arriving home i eventually came to the conclusion that the main (single fan)on radiator was not coming on as it supposed to do so when hot.
Now i presume that the sensor or fan is faulty.
Can someone tell me how i test this i know i need to maybe bridge out the sensor but can someone please explain that to me as i dont want to blow anything ?
Not knowing the car i am unsure whether the 2 front fans should be coming on also which they are not.
Again i dont even know whether im turning the aircon on as dont know how to do this lol.
Can someone help me out it would be much appreciated and explain whether all 3 fans should be running when it gets hot and whether that temp sensor underneath top hose r/h side from front of car actually controls all 3...im a bit lost....
The car is omega 2.5 v6 cd x reg
Thanks in advance
