I have a 1980 looking for a temperature sending unit or might be called a thermo time switch

Those are two separate parts on my '77.

Can you not clean them up enough, shiny brass, or is it the connections that are bad?

I found my thermotine sensor at a junkyard, they are high as a giraffes arse everywhere else.  Temp sensor are available at rockauto.

different things.

there is a temperature sending unit for the temp gauge

there is a thermotime switch for the cold start circuit

there is a temp sensor for the EFI enrichment circuit.

I just thought of something.  The connectors are the same and people hook them up wrong all the time.  You may just swap the plugs around and get back working.  If I remember right thermotine is brownish, temp gauge is greenish or off white?

My temp gauge sensor has a single wire, bullet connector.

Thanks mine is by the thermostat housing has 2 connectors the plugs in

if I clean the brass would that maybe work ?

my gauge on the dash does not work

you should get a service manual, it will help you with what does what.

Yes.  Calcium from the water covers them over the years and they lose their sensitivity. Wire wheel, sandpaper whatever you have that won't gouge it.  Clean all three. The wire on the temp gauge may need the female end squeezed together
