need4speed Posted July 6, 2015 Share Posted July 6, 2015 I'm using a VDO Vision coolant temp gauge in my V8. Is it imperative that I swap the LR coolant temp sensor for the matching VDO one? The reason I ask is that I thought standard defender gauges were made by VDO anyway? Quote Link to comment Share on other sites More sharing options...
western Posted July 6, 2015 Share Posted July 6, 2015 td5 era gauges are VDO made, if it works ok then leave it, if your not convinced then merlin motorsport or europa spares should be able to supply the correct temp sender Quote Link to comment Share on other sites More sharing options...
need4speed Posted July 6, 2015 Author Share Posted July 6, 2015 Thanks Ralph. Am I right in thinking the thread is 1/8 NPT? Quote Link to comment Share on other sites More sharing options...
western Posted July 6, 2015 Share Posted July 6, 2015 I don't know what the V8 thread is. 1/8npt for a 300tdi 200tdi defender engine is 5/8unf, Quote Link to comment Share on other sites More sharing options...
need4speed Posted July 6, 2015 Author Share Posted July 6, 2015 According to LR Series the RV8 part number is the same as 300tdi (AMR1425) so I guess the RV8 is 1/8NPT as well.. Quote Link to comment Share on other sites More sharing options...
western Posted July 6, 2015 Share Posted July 6, 2015 Yes AMR1425 is definitely a 1/8npt Quote Link to comment Share on other sites More sharing options...
