Sensors on the radiator
I was giving the 'ol Iron Maiden a wash this weekend and while looking and cleaning underneath the bullbar I noticed a loose wire on the sensor that fits into the underside of the radiator. It looks like a temp sensor or possibly pressure sensor... but my Iron Maiden doesn't have computers and other electrical goodies, so there is no diagnostics...
... I have a feeling that it is actually a temp sensor to control the aircon from switching off if the water temp gets too high, but am not 100% certain. Can anyone give me some info on what that is and what do I ask the spares shop for, as the little wire has broken off right at the sensor and I doubt there is enough "meat" to get a good solder joint.

Regards

Re: Sensors on the radiator
I searched the Aussie forums and from what they say, the sensor on the passenger side at the bottom of the radiator, is to switch the aircon off when a certain water temp is reached, and the one on the otherside ( drivers side ) at the bottom is to activate the fan infront of the aircon radiator.
Now on mine the passenger side sensor has a broken wire right at the sensor, and I think the other sensor ( drivers side) is also faulty and in a "closed" position, cause if I have the ignition at the ON position and push the button to switch the A/C on then even on first start in the cold mornings, the fan starts spinning. This should only happen when the radiator water temp is running a little high to force extra air through the radiator.
So if anyone knows the part number ( not that I'll buy these from Nissan), or at what temp these will switch on the fan or switch off the aircon then I can get one of each before stripping the old ones out and making ...... nonsense

Re: Sensors on the radiator
Cedric,
If the water gets to high the Aircon would be the least of your problems.

I will have a look in info I have to see if I can spot something.

Re: Sensors on the radiator
ha ha... true.... but luckily I don't have any water temp issues with the monster radiator on my motor. Its just that I like to have things connected and working. If you find anything out, let me know please.
