the fan should run on for 10 minutes or so if the engine is hot. Its designed to do just that because the engine gets hotter for a while after you switch off. It should however switch off when the temperature drops. As riverside says you need a thermastatic switch (sender) . Don't make the mistake of re-routing the electrical feed so it switches off with the ignition or it won't do its job. I ran my Lux for 3 years without a fuse inserted. (too lazy to fit a new sender)If I hit a traffic jam or stationary traffic I would zip out and ram the fuse back in remembering to remove it when I arrived. [

Its a generic part it doesn't have to be a Porsche sender just one with the right thread and electrical tags to suit your connector.If you have to ask about such a simple DIY job then you would be advised to get a garage to do it (15 minute job tops)
Try Berlyn or Eurocarparts or german Swedish &french

It is a real pain the bum to fit - it's easy (basically unscrew the old one out and screwthe new one in) but access is a pig. It is fitted in the back of the top right corner of the radiator as you stand over the engine bay looking down. If you bend down and look at the back of the radiator you should be able to see it. You basically have to get your hand through a very small gap to remove and refit. I took one look and decided there was no way my hand was going to get through there and be in fit shape to operate any tools so I popped it down to my local specialist. Years of experience means he had made his own piece of tooling for this job due to access difficulties and replaced it in half an hour.
He then ran a test to make sure it was working. The test was that he timed how long it took the rad fans to cool the engine i.e. how long they ran for from switching on to switching off. The Porsche book says 2 minutes with the engine running and 4 minutes with the engine off as when the engine is off only one of the two fans runs to conserve battery power. Mine was outside those limits so he did a bit more troubleshooting and found the thermostat was not working properly, so that was changed. Anyway it brought my cooling times back within limits.

By the way you'll need to drain your radiator. The bung is in the lower bottom corner of the radiator and is a big blue plastic screw with a phillips head. Once you unscrew it the coolant will go everywhere as it doesn't have a clear route to drain and with splatter all over the place. Once you're done with all that and you've re-filled the engine will coolant you'll have to vent the system!
