How are you guys , have a friend with a 84' z28 , stock with 4BBL and 350
engine, or maybe 305, not really sure but it gets hot, his Coolant fan switch is totally gone he sent me this picture below.

I'm helping him getting the right switch and pigtail

If it's the original engine, it's a 305. If he has an electrical fan, those are the correct parts. But, that looks like the top of the engine. Those parts listed go in the pass. side head. You sure it's for the fan?

that's exactly what i told him , those goes in the head !

went today and the broke sensor goes into the thermostat housing , what is that ?
its a 305 Z28

The thermostat housing often has one or two thermal VACUUM switches screwed into it or near it in carbureted applications. EGR, Purge Valve and EFE vacuum systems come immediately to mind. But for VACUUM LINES. Not electrical connections.

Check over in the Carburetor forum for vacuum line diagrams to see which it is.

Electric fan switch definitely goes in the passenger side cylinder head between the two rear spark plugs.
