Reduction adapter for durite temp gauge in defender

payydg said:

Anyone know where to get a reduction adapter to fit a durite electric temp gauge into a 200tdi defender?

I think its M14 1.5 thread to m8 1 thread.

Can't find anywhere that lets me specify in that detail.

Anyone fitted one and know where they got the adaptor from

If it’s a genuine defender 200tdi, not a disco, then the coolant temp sender threads are 7/16UNF, not M14. If it’s a disco 200tdi, then I think that’s 5/8UNF.

On defender does the temp sender scored directly into the thermostat housing? My has beed replace previously with a mechanical gauge and now has an adapter

my temp sender screws directly into the thermostat housing, well just below the thermostat, but same thing really. If it had an adaptor, remove the adaptor and see what thread is there.

You are not alone - you should try finding the right one for an early disco 200TDi! (M16 x1 thread adapter - rocking horse poo)

Indeed, I gave up and fitted my gauge into the lower pipe
