RE: Temperature sensor - 86 Spider

AJ -

Yes, the temperature sensor that you refer to is supposed to be attached to
the fan shroud. I forget exactly how it is held there, but I think there is
space for a small screw. Towards the top, on the passenger side.

If I remember correctly, the aux (electric) cooling fan will run whenever
the A/C is on regardless of temperature. I think that this sensor is there
so if the underhood temp gets too high it will turn the aux. fan on.

I thought that this was kind of crude when I owned my '87. So a more elegant
solution is to fit a temp. switch to the radiator (there is already a bung
with a plug in it there) and wire this to the wires from the existing sensor
after it is removed. This way if the engine coolant gets hot enough, presto
the fan will come on.

FWIW, I never saw or heard the fan run on my car so I don't think it really
needs this, or at least not here in the north east.

I think a thermo switch from a Fiat or VW (can't recall which at the moment)
will fit the hole.

HTH,

Jeff

Subject: Temperature sensor - 86 Spider

The A/C condenser fan sensor on my 1986 Spider just hangs in the engine
compartment.  CarDisc says that the "condenser temperature sensor needs
to be on the air scoop".  Are they getting shroud and scoop confused.
There is what looks like a place on the shroud (passenger side) where it
might go, but it doesn't make sense.  How would the sensor sense hot air
on a plastic device facing away from the engine?  I'm thinking of gluing
the sensor to the top of the radiator.  Any thoughts our there in Alfa
land. AJ in NJ86 Graduate.
