Getting through that list

 

The Sandero is, I can't think it's different for your car.:
8mm
20x16x2mm
Just tight enough to crush the washer, by hand - other posts on this site give a figure.
27mm (1 1/16" AF), best to use a six flat socket.
25.5Nm Not to much, it's only a plastic housing, it's obvious when it's tight enough.
Don't forget to put anti-seize stuff on the bolts when you put them back, and have a look at the captive nuts and get some more before the next change as there's a good chance some will have become rusted up by then?

 

And there's more....
Remember to watch that plate cover!!
