Need a sensor for this.
I want one that kicks about 220 -240 farenheit. Has to have 1/8 npt threads.
I can't seem to find one.
Anyone have a parts store part number?

Doesnt say the thread size.
Instead of controlling a fan it turns a light on.
I tried.
Might check out pegasus, that's where I would start.
Do you already have another sender for an electric gauge (like one that reads a changing resistance as the temperature changes)?
If so, I'd think you could just build a simple comparator circuit and have that changing resistance flip on a light at a preset resistance (temp). You could probably even control what temp the light comes on with a potentiometer. More than happy to help design the circuit if you want to go this route.
Is this for a challenge car or no? If challenge the circuit may be cheaper than the new sender. If not it's probably better to get the right part!
Its a mechanical gauge. The ecm has a sensor as well.
Not a challenge application on this one. This is the miata from lst year. Which is now just a hot rod street rat.
What about the type that uses a open air probe that goes in the fins of the radiator? I have one on the OldWing that has a adjustment on it and when the probe reaches a pre-set temp, it sends voltage to the fan. When the temp drops back down, it cuts voltage. Basically it's a thermally-activated relay and could power on/off any 12VDC devices under something like 15 amps or whatever.
You need The Big Balkamp Book. It's under the counter at NAPA - the online version is not currently available. Lists hundreds of sensors with the trigger temps, thread info, etc. I suspect RossD might have access based on his answer :)
I want to say Mopars used 1/8 inch pipe thread on their temp senders back in the 60's and on, but I am not sure whether that's actually true. Finding a sender that will come on below 260 might be a challenge, too. Also, Chryco was big on temp gauges, so they might not have a lamp type sender readily available.
Standard TS17 is the one I'm thinking of, but its definitly for a gauge.
Edit: TS149 says its for a light.
That TS149 sensor is in a ton of ChryCo stuff including the Conquest which I found odd. I can't find a trigger temp point for it though. Probably fine that it just comes on.
In reply to Keith Tanner :
I check the RockAuto universal parts is all.
Good news! The Balkamp catalogs are available online!
Bad news! Now I know why my guy at NAPA keeps the old books around. The current ones just have pictures.
Good news! The real ones are also online!

Engine Management Reference Guide has coolant sensors starting on page 22. They're listed by terminal style, NO vs NC, temperature and thread. You could use a fan switch to control a light, although it will may have different on and off temps.

Wow, that’s like the holy grail of parts! Bookmarking that page.
