Can anyone tell me which part number is the correct sensor for a 1978 300D, auxillary fan temp. sensor at the thermostat housing?
The old part looks absolutely nothing like either of the two new ones. One has 212 stamped on the side, and is a little switch, while the other is larger, but with one pole as well.
Also, the larger sensor has 7G F 3131 stamped into it, the smaller, 4/0 185.11 100C
