R18DrawSide.gif (13205 bytes)A detailed view of the R18

I get a lot of questions regarding technical details and diagrams of the R18, so I decided to add this page to my site. I will try to add new data to it from time to time. It's not my intention to scan my complete manual, but I will upload some of the most requested items. They are all in Dutch. Please don't expect a translation soon!!!

(All diagrams are from "Vraagbaak Renault 18" by P.H. Olving, second edition, october 1984, Kluwer technische boeken B.V. Deventer, ISDN 90 201 1616 9)

Wiring diagrams

The wiring of the R18 varied through the years, so there are several different diagrams. I will add more later.
