bazza Posted November 29, 2007 Share Posted November 29, 2007 Are the temp gauge sender units in the 200tdi different for the disco and RRC? i fitted a 200tdi into my RRC (replacing the 2.5VM) and the only thing that aint working is the temp gauge, it works fine when earthed out though and the temp gauge worked when the engine was in the disco chassis. im guessing they work at different reseistance?

ciderman Posted November 29, 2007 Share Posted November 29, 2007 I recon they must be . I fitted a 200tdi Disco lump into a 90 and had to change the sender to get an accurate reading on the gauge . Try a sender from a RRC 200 tdi . Quote Link to comment Share on other sites More sharing options...
western Posted November 29, 2007 Share Posted November 29, 2007 (edited) Defender 200Tdi 11L engines uses PRC8593 Discovery 200Tdi 12L engines either PRC8001 -- Orange or PRC9917 -- Green, Gulf states vehicle use PRC9942 -- no colour detailed RRC 200Tdi 14L engines use AMR1712 no colour code detailed. that should help fitting any 200Tdi that isn't a correct Defender high mounted turbo type [see photo below- taken from standing above looking down] in a 90/110/Defender fit sender PRC8593 to make the temp gauge read correctly.
