I'm not familiar with the Modus but from what I know about the 1.6 K4M engine the starter motor is underneath the exhaust manifold so the starter motor will have to come out from underneath though you can undo the 3 starter motor retaining bolts from above and the 2 electrical connections from below.
You might to have undo the exhaust manifold from the cylinder head to get enough room to manoeuvre the starter motor out?
It is possible to do it from underneath, but it's a pig of a job.
Best way i found is to remove the exhaust manifold then you can do it all from above.
One thing about renault is they have put some decent nuts on the manifold so they come off easy!
