Alain:

I was waiting for someone in the group that had more repair experiance
than me to answer your problem, I had the same. I have been trying ways
to stop the leak at the temp switch with a number of different O rings
and using pipe tape on the threads, To no avail! My expansion tank is
just to the left of the coolent tank that you get to from the licence
plate. Take off the engine cover to work on it.

Couldn't buy just the NOS O ring so bought the whole switch. Part #251
919 372 cost $8.60 US. Problem solved! Easy fix, Disconnect, screw out
old and screw in new and connect.  Good luck....
