1998 Tdi Galaxy, Where Is Temp Gauge Sensor & Thermostat

[dieseldogg]

OK

I have searched and also checked the FAQ

So

I have mislaid/cannot find my Haynes manual, nor can I find the thermostat or identify the sender unit/sensor for the temp gauge.

I know the weather has been exceptionally cold but from memory over the past 12 years the gauge should have been registering/registering higher, i think the thermostat is Ok as her be blowing hot air, whilst the top hose still be cold.

Thanks in anticipation

Not sure exactly where they be - perhaps some of the pirates on here can tell you

I should add that as far as I am aware our aux heater has not worked this goodly no of years, I may even try & get working again with the help of this forum as I was interested to see that this seems to be a common failing :)

the sender is a combined sensor that serves the ecu with info as well , if you remove the plastic engine cover if you still have one fitted more or less in the centre in front of the rocker cover a water hose comes out and you will see the sensor in there usually has a 4 wire push on connector on it, be carefull taking it off as the wires get very brittle and are a sod to fix back in

you can swop it by removing a circlip that holds it in have the new one ready and do a quick swop over and you only lose a bit of water. if your getting hot air the thermo must be ok, its well under the engine, tricky to get to without a lot of stripping down.

Thanks,

erm Plastic engine cover? :) A very early casualty of my home maintenance regime.

I pulled a 4 wire sensor from the bottom of the top radiator hose , about 150mm out from the head (& there is another sensor just at the plastic "tee" piece next the head)

Anyway i dunked this pulled sensor into a jug of hot water straight from the kettle, with the ignition switched on.

No movement seen on the temp gauge, so i presume this one is buggered?

Or it is not connected to the gauge? i.e. is it the wrong one?

I suppose I could be cunning and source a temp gauge sensor from the motor factors and then see where it fits?

Ps

Re the thermostat, yep i figgered it was Ok, anyway having heard it described as "a complete pig" to replace, not that keen on investigating "just in case"

Cheers
