thermostat switch 3 connections
I had to renew the thermostatswitch in the radiator of my Porsche 928 1978.
It used to be a switch with 2 connections. The alternative part for this is
an Audi switch with 3 connections, apparently for 2 temperatures (as on my
former Audi 90 2.6E). My Porsche only knows one speed for the fan so I want
to connect it to the lowest temperature of the 2 available on the new
switch. Which connections should I use?

Hi,
I don't know how they switch, but I would suggest you put a multimeter
on it and heat it up (with a hair dryer on in near-boiling water. That
way you should well be able to determine its switching behaviour.

On the Audi 2,6E the first switch closes at 92-97 deg C and the second one
at 99-105 deg C. The terminals on the switch should be marked "1" for the
low temp, "2" for the high temp and "+" for the common terminal. Connect
between "+" and "1".
Try Christoph's metode - put the thing in water and heat it up - the low
temp switch should close before it boils (100 deg C)
