Name that sensor/sending unit
Trying to find the correct part # to replace these two.
1989 Trans Am - 5.7 TPI
#1 the top part was broken off.
I'm pretty sure #2 is coolant temp sender, but I'm not seeing the right part# online to replace.

Re: Name that sensor/sending unit
#1 is probably the fan switch. If it came from between the #6 & #8 spark plugs, that's what it is.
#2 is the temp gauge sending unit. Should have come from between the #1 & #3 spark plugs.
The one you buy in the store won't have that mushroom style connector. It'll be a blade. The plug on the wire will plug right onto that just as well as it did on the mushroom.
Both of those parts are 3/8" NPT thread, screwed into a 3/8" - ½" NPT bushing. That's because newer heads have the smaller hole in them, and somebody used the bushings to make them fit into a larger hole. Looks like you have older heads on your car. Make sure you take the bushings off of the old parts before you throw them away.

Re: Name that sensor/sending unit
Thanks for the quick reply! I do have some TFS heads that are now about 12+ years old.
#1 - I lost track where it came out of, but it must be that and I have forgotten what kind I had. I bought a new JET fan switch 60600, but does not look anything like this older one (must be bushing added).
#2 - Yes, saw the blade only style online. Makes sense, thanks!
