need help for location for water temp sensor for gauges on RB25det

[monkeyofdrift]

Hi I need pics or locations (pics would help alot) this is for Defi gauges, I have both oil temp and water temp defi gauges, I have a clue on where put the water temp sensor at, there's 2 plugs for the water temp, the left one has 2 wires but the fiting is too big for the sensor to screw right in, and the left one which is small and has 1 wire and might fit the sensor, and as for the oil temp gauge I have no clue on where to put that, people at the audio place say to drill a hole in the oil pan and install the sensor but i'm like "is there anyway besides drilling" isn't there a sensor for the oil temp to go on and replace with the defi sensor??? Thanks for reading guys and any info would help me out alot. pics would even help this problem out. thanks. this is for a RB25DET.

here's a pice of the pipe that has the two sensors

trying to help you on the other forum.

...so what is it. did the defi gauge just not come with its own water sensor?

[Bluefire]

get a greddy radiator hose adapter for the water temp or just replace the single prong water sensor with the aftermarket. As for the oil temp get a oil filter sandwich adapter. Then you'll have a port for oil temp and pressure

^ told him that on the other forum. not sure if i just wrote it all wierd or i suck at english.

but hes not picking it up

[monkeyofdrift]

lol sorry, yea the defi came with the sensor, I wasn't sure which one to put it on.#2 looked like it would fit the defi sensor, but I wasn't sure if it was the right one.

[krayton]

doooooooooood

adapter! for the love of all thats holy.

ok..at 1 in the am im going outside to take a damn pic for u

[krayton]

try to read what were saying. even iroc linked you to a place to buy the adapter in your other thread.

buy a greddy, apexi, go to summit, or make your own.

You do not want to replace those sensors in your piping, do what everyone is telling you to do and just get the adapters.

Also if you cannot find a sandwich adapter I have one just sitting here with the water hose adapter you need both are greddy. Since I have Oil Filter Relo Kit and Greddy Aluminum Radiator pipe I do not need either of them.

I would seriously consider the advice you are being given, those sensors were put there by the factory for a reason and it does not have anything to do with giving you a cool gauge to look at. The RB26 actually has the temp being read by the ECU so it is not to far fetched for the RB25 to have the same thing going.

look here: http://www.racingworks.com/gauge_misc.htm

you should use the adapter for aftermarket water temp sensors, unless you want to tap the aluminum housing.

[monkeyofdrift]

cool, I'll get the adapter then, I hope it will fit the the defi water sensor probe, lol thanks for your help guys.

The single prong sensor is just for the water temp gauge in the cluster and can be removed. The double prong sensor is for the ecu which should not be removed.

What would happen if someone were to lose the #2 sensor???would a regular 240sx replace the one I drop and cannot find man, Im a big dumb ***, I wanted to see if the defi gauge one fited but it didn't.I'd try to find those tread adapter, it will fit the defi sensor but it was a tad big for the water temp sensor on #2. damn its only off by soooo little. well I hope I can find that #2 sensor, If not I'm thinking I'll pull off one from a 240 or a 300zx and see if it fits Cross my fingers.

[Slo_240sx]

LEAVE NUMBER 1 SENSOR ALONE! That is our coolant temp sensor and your ECU needs it to base your air/fuel ratio. As for number 2 sensor, lose it? I hope you aren't using the RB one because you are SUPPOSE to use the Ka temperature sending unit (number 2). If you still have the RB number 2 replace it with a Ka one right away because it does not match your gauge at all and say you are overheating. Do what everyone says, sandwich adapter for the oil temp, and either get a greddy hose adapter for the temp sender or tee it off of the stock temp sensor with the correct fittings.-Alex

[monkeyofdrift]

Thanks Alex, yea it was the RB one I lost, I'll go to the junkyard and pick up the KA sensor, yea I'm leaving the #1 sensor alone. I'm going to order the adapter for the water temp sensor, lol wish they made a tread adapter. lol it's Junk'R UStomarrow then. Thanks for everyones help.

[monkeyofdrift]

oh yea for the adapter, I needed Measure the inner diameter of the Upper Radiator Hose, Does anyone know the diameter the the hose??? for the RB25det.

yea alex I just got the 240sx temp sender, and the gauge in the S14 still reads high lol. I going to just use the aftermarket water temp adapter. Thanks for helping I wish I could fix the problem with the water temp in the stock cluster.

Are you sure you can't use the RB #2 sensor? That's what I am using and it reads perfect on my dash. I even checked it against the nissan CONSULT scan tool and its right on.

lol i don't know what I did wrong, I just got a brand new 240sx water temp sender, but it didn't change nothing the needle on the gauge still at high.

[Slo_240sx]

Then you are overheating. Get it fixed or motor goes BOOM bye bye Monkey.-Alex

lol, it shouldn't be, the needle just goes on high when I just turn the key, that's why instead of using the stock gauge i'm going to use the after market water temp gauge. I've been driving the car for 40min (somedays) and nothing happen, I know I know, don't drive the car without knowing the health of it. hopefully when I get the adapter for the sensor, that will fix that problem.Thanks for helping out.
