89 B2200 temp sensor
They cost about $35.
Are they really this expensive? This sensor goes to the bottom of the radiator with two wires. I tested it and it is open, no resistance reading. I heated it up with a gas lighter and no change. What is the resistance reading at 35F, 60F and 180F? Any ideas? Thanks for any reply.

11 views and no replies. C'mon guys, somebody knows about this.
Ok, I only have the Haynes manual and it has no mention about this temp sensor. Maybe somebody has a Factory Service Manual and can look it up for me. Is this just a switch, temp dependent resistor, or a thermocouple? Thanks in advanced.

I found a cheaper one at Advanced. $26
I tested it with my fluke meter. Still confused. New one has neither resitance reading nor millivolt reading. Not even a switch contact that makes when heated. I will install it and see what happens.

Finally traced the temp sensor function that is located in the bottom of radiator.
It is not a temp sensor, it is just a cold temp switch. The switch makes around 55F and opens around 60F. Tested the switch by dipping in iced water and the switch closed using a digital meter. This cold temp switch activates the PTC heater in the bottom of the carb to prevent the carb from icing up during cold weather start-ups. Just for everybody's info.
