SupraSapphire Posted February 1, 2004 Share Posted February 1, 2004 Can anyone tell me what type of thread a standard sump plug has? I've got a HKS oil temp sensor, that's supposed to plug into the sump. The sensor itself is smaller than the sump hole so I need some kind of adapter to convert it from its current thread to the sump thread. When I came to do an oil change the original adapter was thread bear so I had to fit a standard sump plug. I seem to have lost the old adapter now and could do with some help sorting out a new one.

SupraSapphire Posted February 1, 2004 Author Share Posted February 1, 2004 Here's a picture of the sensor. If anyone can supply a sump adapter I'd be very interested. Link to comment Share on other sites More sharing options...
Dragonball Posted February 1, 2004 Share Posted February 1, 2004 Alternatively we do a relocation kit - part of which is a remote head that holds the oil filter which has two fittings - Into one of which you can thread this sensor (and the other can be used for oil pressure sensor at a later date if required) Give me a mail if you want details Regards Paul http://www.mpaconsultancy.co.uk/miamirice/images/Oil%20Relocator_small.jpg Link to comment Share on other sites More sharing options...

Post a similar quality photo of it next to a standard sump plug, or tell me the exact thread and pitch size of the oil sensor. I may be able to make you an adaptor. Obviously, it can't be done if the sensor thread is nearly as big as the sump plug thread, i need a reasonable amount of wall thickness left when i tap an adaptor to go into the sump hole, and drill and tap for the sensor. Plug is metric fine thread. Link to comment Share on other sites More sharing options...
SupraSapphire Posted February 1, 2004 Author Share Posted February 1, 2004 Thanks Chris, I'll email you the details. Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 1, 2004 Share Posted February 1, 2004 Actually, thinking back, i have made an adaptor for someone else on this list. the thread size was too close to the sump plug thread size, so i turned and tapped and died a stepped adaptor, so the tip of the probe was in the oil, and the threaded part was further out. I have to warn you any 1 off machining work ain't cheap, I'd want 50 quid to make another, it's a fair bit of time to do these as single items, and not enough demand to write a CNC programme to do a batch. I'd need the probe too, to check on thread size and pitch. Link to comment Share on other sites More sharing options...

Supra ST Myster Posted February 2, 2004 Share Posted February 2, 2004 i thought i read somewhere that trd mounted the sensor in the actual sump plug by drilling it and screwing it in that way? Link to comment Share on other sites More sharing options...
Dragonball Posted February 2, 2004 Share Posted February 2, 2004 The problem is as Chris identified - the sump bolt is very small and cannot really take the required thread diameter for the sensor to be plugged straight in I am sure that it has been done - but cant see it leaving 5mm either side Hence the reason why I went the relocation route initially when trying to fit the sensors in place (I have oil temp and pressure) - and the filter is a pig to get to unless jacked up Mine is now happy under the nearside headlight - which doesn't take too long to get at:thumbs: Link to comment Share on other sites More sharing options...
SupraSapphire Posted February 2, 2004 Author Share Posted February 2, 2004 I'm gonna send the sensor to CW and he's going to have a go at making an adaptor up for me. I'll let you know how it goes. Link to comment Share on other sites More sharing options...
