      When idling the engine temperature quickly goes to the red. I already installed an auxiliary electric fan, but that is hardly sufficient. Anyone recognizes this problem and has a solution? Bigger radiator?

        I have never had any problems with standard radiator.
        Maybe the water pump is not working propably?

          I had a similar reaction on my Sonett some years ago, I solved it by changing the radiator cap, the water was not circulating properly. Sometimes you gotta be lucky 🙂

          Best Regards and good luck

              How old is the radiator? If it still has the original cooling block it is time for a recore. I had the rad of mine redone with the core used in a 99 Turbo as preventive maintenance 14 years ago; still works like a charm.

                At least 20 years (has been stored 20 years). This was one of the solutions I was thinking of, maybe even a bigger core. Where was it done (Norway or Holland)?

                  In Holland. Where is the sensor to the electric fan located?

                    No sensor, manually operated :).

                    (waar heb je jouw radiator laten opknappen?)

                          I ordered and installed a new radiator cap. Now waiting for the results 😉
