rest assured no k seal or any other sealing product is going in the system !
mechanic meant stick silicone sealant on the outside of the threads between gap/plastic i.e. just rub finger round outside don't undo the switch.
Replace the rad when you get back. Relax, chill out, you'll be fine.
I intend to do just that !

Probably a silly question but have you got the fibre (similar) wash fitted to the fan switch?

Yes probably, mine was an pre 84 so from memory it was fibre but I think later ones are copper.

I wouldn't reuse the copper sealing washer, it will most likely be a very soft metal that once deformed could need replacing in order to get a seal.

good point but with the amount of PTFE tape i wouldn't think this is an issue...saying that I've taken it out 3 times !
think is 22 x29 o ring !

If you are inserting the thread into plastic you will not be able to tighten down enough onto a copper washer, usually it is an o-ring for plastic. Can't remember what mine had when I did it years ago. A fibre washer would be more preferable to copper on plastic I would have thought.

The o ring that came with the Meyle switch was copper looked like two bits of copper squashed against each other
I purchased another switch from GSF on way home today and the o ring is flat and silver which is more looks like the material type but metal

I know the photo isn't from the side but from what I can see, there isn't any ptfe tape 'spoil img' and visual from the outside. Have you put enough on?

Yes What2do is right ptfe will create an o ring with over 20 turns of tape.
As the thread runs in the excess ptfe squeezes out forming a sealing ring.

Thanks for all your help, before we left I redid the ptfe tape and almost a week in and towing the Eriba all is dry.
Lots of waves from the Dutch with the Eriba - I'm not sure if it's out of sympathy though !
