1983 280zxt water temp gauge not coming on


Recommended Posts

Hi everyone. On my pride & joy, the 1983 280zx, the temp gauge does not come on or show in the dash.  Once in awhile it comes on intermittently for a few seconds just enough for me to see the current temperature. Luckily it does shows normal level, about halfway.  I've been living with this issue for several years but now the radiator electric fan does not come on during hot summer drives. I think the prob is with the temp sensor? Here's the pic of the one-wire type sensor that's bolt on at the bottom of thermostat housing.  Can someone confirm that the elec fan problem is related ? or how can I check this? Also I'm having a real hard time finding a new one-wire sensor out there, could someone point me the right direction. Thanks in Advance !!

Welcome to HybridZ, and thanks for your question.  Please feel free to introduce yourself and your car on our "New Members Forum":  https://forums.hybridz.org/forum/68-new-members-forum/

 

Are you looking for something like this?  Note the exemption in the text "*Not for digital dash on 280ZX." -- don't know if that applies to your car.  (I'm guessing not, since your current sensor is single wire.)
