Adam001 Posted May 1, 2010 Share Posted May 1, 2010 Hey, I have a disco 200tdi fitted to what was a 19J TD. I currently have the 19J coolant temperature sensor but I want to replace it with a aftermarket digital system. Can anyone tell me what size thread the fitting is?

Retroanaconda Posted May 1, 2010 Share Posted May 1, 2010 It's 5/8"-18 UNF on the Defender 200Tdi, don't know for sure about the Disco variant. I have no reason to believe it's different, but you never know... Quote Link to comment Share on other sites More sharing options...

I have no reason to believe it's different, but you never know... When I fitted a digital gauge to my 110 I just drilled out and tapped the old sender to 1/8 NPT to accept the new digital sensor, there's a thread about it somewhere.

Adam001 Posted May 4, 2010 Author Share Posted May 4, 2010 I will likely do the same in that case, unless the kit comes with adaptors Related question? anyone know the thread size for the oil pressure switch, want to fit a t piece for a pressure gauge Quote Link to comment Share on other sites More sharing options...

Adam001 Posted May 4, 2010 Author Share Posted May 4, 2010 I'm pretty sure thats 1/8 NPT too ... Thought the consensus was that the coolant was 5/8" -18? which I can tap out basically thinking of putting a splitter block on the oil filter housing to add a pressure and temperature gauge sensors Quote Link to comment Share on other sites More sharing options...

I've done some digging and the concensus is that the oil pressure switch is 1/8 NPT. Quote Link to comment Share on other sites More sharing options...
Adam001 Posted May 4, 2010 Author Share Posted May 4, 2010 Cool that makes things much simpler as most splitters are 1/8NPT Quote Link to comment Share on other sites More sharing options...
Dads Toy Posted May 4, 2010 Share Posted May 4, 2010 Make sure your T piece comes out far enough. I've got an electric sender complete with warning light switch but the case fouls the oil thermostat when you screw it in. I'm now looking for a straight extension with 1/8 NPT male one end and female the other. Anyone know where to get one? I can find T pieces and may have to use that but then would need a blanking bolt! Malcolm Quote Link to comment Share on other sites More sharing options...
western Posted May 4, 2010 Share Posted May 4, 2010 anyone know the thread size for the oil pressure switch, want to fit a t piece for a pressure gauge you can use the LR genuine bits for this, have a look here Quote Link to comment Share on other sites More sharing options...
Dads Toy Posted May 5, 2010 Share Posted May 5, 2010 Thanks for the diagram Western, ETC4033 is exactly the part I need. How do you find parts like that as they don't seem to appear in any of the diagrams I've found? Malcolm Quote Link to comment Share on other sites More sharing options...
western Posted May 5, 2010 Share Posted May 5, 2010 usually in the list of parts to the left of the diagrams but not identified on the diagram, it just good old LR used the same oil filter head on the older 2.5 diesels & the 200tdi, so it just bolted together Quote Link to comment Share on other sites More sharing options...
Adam001 Posted May 10, 2010 Author Share Posted May 10, 2010 That looks perfect Where do you get these bits from? Quote Link to comment Share on other sites More sharing options...
