stuck Posted February 25, 2012 Share Posted February 25, 2012 Gents, I need a new throttle position potentiometer for a 3.9 (non serp) Our favourite Russian website lists the two part numbers in the title, one for a 31D & one that isn't. I haven't a clue what 31D refers to (serp front end?) so could someone confirm which part number I need please? Thanks, Mick. Quote Link to comment Share on other sites More sharing options...
western Posted February 25, 2012 Share Posted February 25, 2012 ETC5598 http://www.paddocksp...entiometer.html says it's a RRC/Discovery V8 item ETC6443 http://www.paddocksp...entiometer.html & http://www.autoelectricalspares.co.uk/lucas-seb201-73305-215sa-etc6443-throttle-pot-546-p.asp . Engine (e) numbers: 31D = 3.5 liter; 38D = 3.9 liter through 1992; 36D = 3.9 liter from 1993; 40D = 4.2 liter. Quote Link to comment Share on other sites More sharing options...
stuck Posted February 25, 2012 Author Share Posted February 25, 2012 Thanks Ralph but I'm confused, Paddocks states ETC5598 is for a "3.5 V8 EFI except 31D engine" Your list says a 31D is a 3.5? Mick. Quote Link to comment Share on other sites More sharing options...
