Temp Sensor

[Jez13]

Hey guys,

Just had an r33 gtr engine installed on my 32, everything is good except for my water temp sensor (the one on the front of the engine) might not be working. The wiring had continuity because when i touched the end on the valve my guage went to full, so obviously my guage is working also. These tiny little simple screw like things cost over $100! Thats how much I paid for my clutch master cylinder and booster...anyway, how could such a simple component break? Can I spray it with a magic solvent like WD40 and all will be good?

Has someone used teflon tape on the thread?

I have a spare one ..changed mine to check if the old one's working and it was. You can have it for $50 if you want. it's from an R34 GTT so just confirm if it's the same (should be) and pm me if interested.

I am going to look up if its the same. If it is I am interested. Cheers!

could be that the gauges in the dash read differently (honestly don't know). do you happen to have the stock one from the r32 motor? if you do i'd put that in (if it fits) and just use that.

i'd take a stab and say the above is correct, you probly just need to get one off ur original motor, or the same part from another motor, or a new one to suit your original motor.

Gauges and senders have to match.

for eg. In the daily driver sss, put a new motor in it, not knowing that whatever jdm awesome car the engine came out of, had a dif gauge temp sender, now my gauage reads oddly, but due to the stupid position of the sensor, its not being swapped over

Oh yeah...bugger if it doesn't work. I may have to install a custom one because I doubt that the r32 sensor will work or fit. As avril says, 'why does it have to be so complicated'. Just anpther gauge i have to crowd into my cockpit. Unless the r32 sender does actually fit. I dont have my old motor so I will have to borrow one from somewhere.

id be pretty confident in it fitting really. if not, thread adaptor, much easier than putting another gauge in.

RB20 and RB26 ECU water temp sensors are the same but RB25 is different, not sure if Neos are different again.

When I first built my 30 I snapped the RB20 sensor and only had 25 one lying around, ran in cold start all the time until I put an RB26 sensor in.

So rb20 and 26 are the same but 25 is different? I have a 26 installed from an r33 gtr in my 32 gtr so it should work right? If an rb26 sensor from a 32 and a 33 are the same....unless I have a twin turbo 4wd rb25 with an rb26 cover...oh shit.

Just to wrap my old topic up because I finally found an answer. Also so if anyone were to sticky this it wont be a waste of time reading it becuase it has a conclusion now.

If you have an R33 gtr engine in an R32 you need to use the R32 GTR water temp sensor (installed at front of engine head) for your gauge to work.

Thanks

yeah that sounds about right.
