Temp sensor - Now I'm confused. Which ones goes where for 3.2

[rolls 912]

Hi
I'm trying to work out what's what as I'm new to 3.2s. The front sensor next to the pressure sender is for the temp sender (operates the temperature gauge).

Could someone please advise whats the one for under the inlet manifold with the black plastic connector (on the crankcase breather).
Cheers

If this is the sensor, it's for the oil pressure light.

The external oil cooler fan temperature switch is located on the cooler.

Good luck,

Gerry

So then what does this sensor actually do and what does it connect to? Efi module?

Beside the write-up in the note (see below), I don't know.

Its fitted on mine but I don't have that cooler.

Make sure that your fan is working well with a new thermoswitch. This switch senses when the oil temperature gets hotter than a certain amount, and then turns on the fan. The stock switch turns on around 240-degrees Fahrenheit (110-degrees Celsius), but you can replace it with a cooler one that turns on at a lower temperature. Some slight wiring modifications may be required in order to use the cooler thermoswitches (they have different connectors on their ends).

Factory Late Model Carrera External Oil Cooler

This late model oil cooler is a direct replacement for your front mounted trombone oil cooler. Originally installed on the European 930S models, this cooler kit will serve your engine better, providing much better cooling under hot running conditions. Easy installation, and your 911 will be running much cooler, resulting in longer engine life. Fits all 911s with the 'trombone' style oil coolers. Kit also includes all hoses and brackets required for a bolt-on installation. Oil Cooler Kit includes:
Late-Style Carrera Oil Cooler
2 Upper Flexible Oil Hoses
Oil Cooler Stone Guard
Lower Cover Plate
Small Oil Hose Gasket
3 Rubber Mounts
Upper Mounting Bracket
Lower Mounting Bracket
Also highly recommended is the outer foam seal that seals the stone guard to the fender well, and forces air through the cooler. If you want to relocate your horns gracefully (without banging the heck out of your fender strut), then you will need the horn relocation kit as well. This kit contains the two brackets that you need to relocate your horns for all cars 1974-86. If you are not going to be using the electric fan with this cooler, make sure that you plug the thermostat hole at the top of the cooler before starting the car! The entire procedure for upgrading your oil cooler is documented in our Pelican Technical Article: 911 External Oil Cooler Upgrade. Don't forget to add the Pelican Scoop for maximum cooling efficiency out of your new cooler!

110C/230F is a bit higher than I prefer.

Here are some other choices:

1. The Nasson can be ordered for almost any temperature, the choice for our '86 was ON-210F, OFF 197F.





2. Also, the BMW sensor.



I saw a post on this forum where the BMW was installed with good success.

Good luck,

Gerry
