Broke off the temp gauge sensor this morning after I finished draining/flushing the radiator of my K100LT '88.

The part # is 62161459270 (Temperature sensor, water)

Was lucky to unscrew the threaded stub using finger strengthen only so didnt need to disassembe the water body.

Can anyone please suggest an alternative part for the sensor-Japanese items would be more readily available here both new or used.

Cheers

you will find the right thread ...but maybe not the same length ...shouldnt be an issue ...but what will be an issue is the resistance at 100 degrees c ,,,there are quite a few standards

i have modified an after market guage to suit my bmw sensor seems to be close on the indicator for this task,

good luck ..!

Thanks Charlie,

So if i get a sensor (or have one fabricated) with a resistance of 307ohms at 87C (as mentioned on the sensor body) i should be ok?

hmm.... dont be confused by the electronics for the engine management farzand .... the temperature sensor for the guage us a completly stand alone device

the electronic troible shooting guide points to one in the water stub that turns the fan on and cintrols the injection system ...here is another sensor ...mounted in the oil/water pump assembly (12mm x 1,5 thread from memory )

and has wiring direct to the temperature guage

hope that helps

Yes, thanks. Had figured that out. I just want an accurate as possible reading on the gauge thats all.

Not at all fidgeting with the sensor behind the radiator.

Will report when done.

Thanks

My understanding is that most sensors are set up the same (for cooling water) 90'C is 50 Ohm. Have a look, there's a lot of info on the web. Motometer and VDO have similar ranges, just don't mistake an oil sensor/gauge for a water one. IIRC one goes from 40 to 120 (oil) and the other one from 50 to 150 (water)? I have used the Motobins sensor with a VDO gauge and its spot on with the infrared thermometer.

+1, exept it`s the 40 - 120^oC that is used for water temp,
and and have a specific sensor.

The values should be ~: 20^oC = 250 ohms, 60^oC = 135 ohms, 90^oC = 50 ohms.

The threads is M10 x 1,0.

hey rene ! we had to add about 80-90 ohms from the bmw sensor to the newer style auto meter (usa style) type temp guage .they listed a different type of sensor as being suitable ...but now nla ...

just a heads up

Charlie, "over there" other sensor values is used on additional gauges.

Have a look at this:
