2 post temp sensor?
I was reading some posts about temp sensors. I have 69' Firebird 350. When I got the car it had a 2 post unit installed. One wire comes off the alternator and one goes to the dash?
At some point I messed with it and a post broke off. That got me wondering if i should have a single post? Either way I replaced it with a 2 post since that is what was in it. I put the wires back on as they were. When you start the car the temp light comes on. When it warms up it goes off. I've never overheated so I can't speak to other end. I'm guessing this isn't correct? Coolant level is fine. |

You will have to use the post R on switch that closes the circuit @ 246° to 266°F for the dark green wire.
Terminal G (not used) opens the circuit @ 129° to 93°F. HTH |

On my Catalina the two post sender was used when you had a cold engine light on your dash it would go out after your engine warmed up.

So I guess I'm still a little confused. I don't have a "cold engine light" but is the 2 prong sensor working properly or not? The light goes on at start up and off at temp. Sounds good... assuming it would go back on when overheating?

If you put the dark green wire on switch terminal marked R you will be fine. The TEMP indicator lamp will light up at "start" and off as engine starts. Last edited by Kenth; 07-28-2021 at 03:48 PM. |
