dbartle9 Posted July 26, 2012 Share Posted July 26, 2012 Hi all, I'm putting together the last couple of bits on my 3.9 V8 Defender installation, and I'm struggling to identify the gauge temperature sender thread. Searching the forum found plenty for 300 Tdi etc, but not much for V8's. I've fitted a Td5 dash already, and I'm planning to buy a VDO Vision temperature gauge and matched sender like this: http://www.merlinmot...oduct_info.html Available sender threads are 1/2 NPT, 1/4 NPT, 1/8 NPT, 5/8 UNF, M10x1 and M15x1.5. Anyone have any idea which one I need? Engine is a serpentine from a 1995 Disco if it makes any difference. Thanks, Dave Quote Link to comment Share on other sites More sharing options...
94Discovery Posted July 27, 2012 Share Posted July 27, 2012 If 95 is the same as 94 serpentine nas then it is 1/8 npt ,iam doing the thore manifold and had to drill for it Quote Link to comment Share on other sites More sharing options...
iomlt Posted July 27, 2012 Share Posted July 27, 2012 If you have done the modification to the dash wiring harness then i sound that the V8 temp sender works perfectly. i have a 3.9 efi multi belt. Quote Link to comment Share on other sites More sharing options...
dbartle9 Posted July 27, 2012 Author Share Posted July 27, 2012 Thanks for the replies. Reason for getting the VDO gauge and sender is to have actual temperature in deg C shown - I like to see how/when the engine temp rises. Dave Quote Link to comment Share on other sites More sharing options...
