pedrosixfour Posted September 13, 2011 Share Posted September 13, 2011 (edited) Hey folks. This isn't my actual sender unit but I find myself in the same situation and mine is of the same variety. I have no part number for it so I have no idea if the current HKS range is compatible Anyone have any ideas where these might be bought new or even second hand provided they are in useable condition. I need two, one for the oil temperature and one for the water temperature. The same sender would probably suit both applications. Would I be right in thinking that any temperature sensor with two wires coming out of it could be could be joined to the original wiring & plug? Thanks in advance of any help.

Lude Posted September 13, 2011 Share Posted September 13, 2011 hi mate, ive got greddy gauges, they will be the same principal. the water temp & oil temp are the same sender (just a thermometer) so the wires on yours have just snapped off have they? you still have the metal thermometer end & the wires? yea just join/solder them back together if you can (if there is enough wire left at the sender end to attach to) if not ive had replacement gauges from ebay USA....

Chris Wilson Posted September 13, 2011 Share Posted September 13, 2011 Google HKS Europe (here in England UK), ask for Nathan and see if they list new senders still. If not you need to see if they can tell you anything to help source an alternative, or you could see if you can get pins inside the insulation that's left on the senders to get a multimeter on them and measure the resistances yourself, in water that's raised in temp with a thermometer in it, and see if something else will work. I will look for the adaptor for the sump tomorrow, have been out most of today, sorry. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted September 14, 2011 Author Share Posted September 14, 2011 (edited) Spoke to Nathan Chris, he can't supply sensors or recommend anything to use instead. I can repair the oil temp sensor to get the resistance v's temperature change table and hopefully I can match it to some other sensor which is available. On the subject of the sump plug adaptor, please don't waste any time looking for it for the moment as I can't guarantee that any sensor I do find is going to have the same M10 x 1.00mm thread as the old sensor.

pedrosixfour Posted September 14, 2011 Author Share Posted September 14, 2011 I think I'll risk buying one of these tomorrow after I do the resistance v's temperature test on the old sensor tonight. http://cgi.ebay.ie/AUTOGAUGE-OIL-AND-WATER-TEMPERATURE-SENSOR-/270790418246?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3f0c5ddf46 I'll do a similar test on the above and if it reads the same as the old sensor I'll buy a second one and adapt the guage wiring to suit both. I don't see much point in paying €100 for a GReddy unit to be shipped from the US in the hope that it may suit the gauges. Quote Link to comment Share on other sites More sharing options...
scoooby slayer Posted September 14, 2011 Share Posted September 14, 2011 i got one from ebay for £7 altered the wiring and made the hole bigger retaped thread, it works but reads 30c over consistantly. Quote Link to comment Share on other sites More sharing options...

Oil temp sensor snapped at the plug, I have that repaired. Water temp sensor snapped at the fitting, impossible to do anything with it. Am looking for an alternative to one, perhaps both of the old sensors but Greddy prices are a bit rich for a gamble! Quote Link to comment Share on other sites More sharing options...
SupraShaun Posted September 15, 2011 Share Posted September 15, 2011 I had some HKS sensors etc installed in my car - but no gauges I removed them but can't remember if I still have them, I'll have a look for you. Quote Link to comment Share on other sites More sharing options...

Bosch sensor figures: http://www.boschmotorsandcontrols.co.uk/sensoren/sensoren.pdf#page=50 Two extremely useful pieces of information gents, thank you. @ Slayer - Fitting an extra resistor in series to the circuit would probably rectify that problem, wouldn't it? @ Chris - Using Bosch units certainly wouldn't hurt in the reliability stakes but I see the sensors are all M12 x 1.25mm tread minimum, is it possible to retread to 1/8NPT or M10 x 1.00mm?

I've only just spotted this post! If you could do that mate I'd be very grateful. I've done a repair on both of my sensors but I'm none too optimistic at this stage. Both were broken at the probe end but I managed to cut open the outer casings, remove the cement from around the wires without damaging their individual insulation, do a solder and heat shrink job on both leads of each sensor and get them back together. What have I got to lose? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted September 15, 2011 Author Share Posted September 15, 2011 Chris, if you could resume your search for the sump plug adaptor I'd like to get one from you if possible. Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted September 16, 2011 Share Posted September 16, 2011 Hi Damien.. One of the sensors in the link below should be yours? http://www.rhdjapan.com/pinpoint_result?keyWord=Search+keyword&pp_manufacturer=HKS+Japan&carMake=All&carModel=All&carDetail=All&x=37&y=12&pageNb=6 Quote Link to comment Share on other sites More sharing options...

SupraShaun Posted September 19, 2011 Share Posted September 19, 2011 Here you go, this is what I have. The 3 random bits of wire are also gauge related, I just cut the ends off so they were easier to remove from the car. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted September 20, 2011 Author Share Posted September 20, 2011 Thats a temperature sensor alright, the other big item i think is a fuel pressure sensor. The rest of it is wiring to the main gauge harness as far as I can see. Fancy parting with the temp sensor? Quote Link to comment Share on other sites More sharing options...
SupraShaun Posted September 20, 2011 Share Posted September 20, 2011 I seem to remember taking the big item off of a sandwhich plate. Yeah sure, the only thing is though becuase I never had the gauges I can't say if it's working or not. Quote Link to comment Share on other sites More sharing options...

Bearing in mind that the temp sensor is a bit of an unknown quantity what do want for it? Are there any obvious breaks in the wiring?

You do realise that £5 will probably just cover the postage to Ireland, are you happy with that? Quote Link to comment Share on other sites More sharing options...
