The louvers mount in the bottom of the fan shroud. The bellow in the 2nd pic is the thermostat. It connects to the louvers with a rod type linkage to open and close the louvers. There should be a set of louvers on each end of the shroud. Like me, many people don't use them as replacement parts aren't readily available, mainly the thermostat.

So I can leave the louvers out and get rid of the thermostat ? and this will not effect the cooling ?
VW/Porsche engineers worked 50 years designing them! They aid in proper warming up of engine. If it never gets cosd where you are perhaps not a biggie leaving them off. The deflects even if left open do aid in directing engine cooling are. Id' put them on. There is a control rod with sping and a rod out of the bellows thermostat that aren't shown.
It is best to use the fully functioning cooling system as designed.
The flaps help direct the flow of air even when fully open.
Also, in one of the photos you uploaded it looks like you may have the air deflector that fits between the cylinders on the top of the cylinders. It should be on the bottom.
If you do a search on theSamba.com you can find information about all the engine tin.

Pete:
Running your engine without the air vanes and thermostat will cause it to come up to temperature very slowly and then continue to rise in temperature to something higher than if you had the vanes and thermostat in there. They actually make the engine run warmer when it's cold out, and cooler when it's hot out, especially Cylinder #3. In other words, put them in.
There is a set of those flaps on both sides (left and right) of the fan shroud. They are connected to each other to work in tandem with a flat metal arm that connects between them across the back of the fan shroud. All interconnecting stuff is held together with special springs, flat washers and spring clips to hold it all together while not binding anything.
They should all work very freely when assembled and connected (no binding) before you connect the bellows thermostat. If they bind, find out why and correct it.
Install the bellows actuator arm (a short, bent rod) into the passenger side flaps (there is a little loop in one flap to receive it) and then aim the rod down through the appropriate hole between the cylinders as you seat the fan shroud (you'll see it - it's pretty obvious) so that it protrudes from below the cylinders. Again, it should not bind in any way.
Once you get them installed (use 8mm screws and lockwashers) then spin on the bellows finger tight and assemble the mounting bracket to the case but don't tighten it yet and don't put in the screw to mount the bellows to the bracket (yet). Open the flaps fully, loosely assemble the mounting bracket to the engine case and move the mounting bracket up until the upper part of the bracket just touches the top of the bellows.
Lock the bracket into position, then pull the bellows down to seat into the bottom of the bracket, install the mounting screw and tighten. The bellows is keyed into the mounting bracket such that it cannot unscrew itself from the flap actuator rod.
BTW: I have NEVER built an engine without ALL of the original cooling tins, air vanes, thermostat and associated cooling stuff properly installed. I've also never had an engine overheat.

So I got to round up more stuff rods clips etc.
6 mm screws.
I'll suggest again that you spend some time doing research on thesamba.com.
There is a lot of information there about what you should have and how it fits together.

Yeah, I agree.
There is a lot of stuff to remember regarding cooling tins and so forth, and for you it would be easy to leave something out or get it installed wrong.
