Crofter Posted July 19, 2010 Share Posted July 19, 2010 Dose anyone know the size of thread that is used on a temp sender on a 2.5 diesel, the reason I want to know is that i want to fit a new sender to my Isuzu 2.8 and I reckon the 2.5 should be a match to the gauge. The 5/8 UNF one from a Mini fits but gives a hot reading, and i see a 2.5 Land Rover one on sale but don't know if it's 5/8 UNF.

Retroanaconda Posted July 19, 2010 Share Posted July 19, 2010 Think it is 5/8 UNF. It certainly is on a 200Tdi, and people speak of swapping the senders over when doing conversions, without any mention of thread adaptors. Someone will be able to confirm though Quote Link to comment Share on other sites More sharing options...

andy.cowman Posted July 20, 2010 Share Posted July 20, 2010 Correct. Google is your friend Got a horrid feeling the sender for my Durite gauge I have ordered won't fit... 1/8" NPTF sender according to the blurb. Can I modify it to fit do you think??

Retroanaconda Posted July 20, 2010 Share Posted July 20, 2010 You'll need an adaptor to fit into the 5/8" UNF thread in the engine. I got one from here: https://www.europaspares.com/GAUGES/SENDER_ADAPTORS__ETC/1_8_NPT_FEMALE_ADAPTORS_TO_SUIT_MALE_IMPERIAL_BLOCK_THREADS_2020.html But a lot of places sell them, as the majority of after market gauges use 1/8" NPT senders (although for some of the higher end ranges, VDO etc, they do a range of fitments).
