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.

 

#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.

 

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!
