CAUTION: This is NOT plug'n'play, you need a drill press and have to lower, drill out and cut thread so you need the right tools and the skill to do that job; if you're uncertain you better ask for help or let it like it is.
Concerning the switch I can only speak for what I've found on the German market, but the link @ the bottom shows where I got it from and you may get it there or have other sources for a similar component.
1. Drilling out for M14 (Ø 12,5 mm):
2. Thread cutting M14x1.5:

3. Ready for switch:

The alu chips fallen in from drilling I got out with a small plastic hose taped on the snorkle of a vac, afterwards I flushed the rad thoroughly.
4. New switch (#126.246) with washer (same as for oil drain plugs):

5. Built-in:

6. Shrinking tube to prevent premature corrosion on contact surface:

MARKUS: The cooling fan switch 97*c (part # 27010-1180) you can still get from KAW. Partzilla has them for $82.
