Hi, I'm gradually making progress on my S3 project, but today found another query;
The water temp sensor seems to be screwed into a Bakelite or plastic housing which just seems to be push-fitted into the head
This Bakelite housing is cracked and has split into two halves, the lower half is dome-shaped to fit into the head
I've looked for new sensors but they all appear to need screwing into something
Do I need some kind of adaptor?

Hope someone can help
Many thanks

Just been browsing another forum and I may have misidentified what I thought was the sensor, the thing I'm looking at may be an 'Otter Switch', in which case does anyone know where I can get a replacement?

Most likely Dunsfold Land Rover or try Craddocks they do have some of the more oddball stuff.

Many thanks, one last question, someone has inserted the water temp sensor into the Otter Switch. If I remove the sensor and put it in it's correct place, can I just blank off the Otter Switch (the cold start light doesn't work) or do I need the Otter Switch wired up for the other sensor to work?

Just blank it will be fine normally in series with the choke cable switch. You can wire the choke cable switch so its earthed when ever choke is on so you know its still on .
The switch was just to tell you the engine had warmed up enough to allow you to push choke in.

Ok many thanks, it's amazing what you don't find in the workshop manuals isn't it
