I am having a break half way through changing the spark plugs on my Xantia.
The plug change is a bit easier than I anticipated, I could do it in an hour next time.
The plugs that came out of the fron 3 cylinders look almost new and had clean threads. The plugs that came out of the rear 3 cylinders are badly worn and were all tight in the threads. The date codes of the fron and rear plugs did not match. Someone has been cheating I think.
Can anyone tell me where the sensor is for the water temperature guage and what colour is the connector? I bought a replacement (specifying clearly that I wanted one for the guage, not the fans) which has a brown connector, but the water sensor on the top water pipe has a green connector. The sensor on the bottom water pipe has a brown connector, but I would expect that would be for the cooling fans.
Lastly, I have noticed that the LHM return hose from the front HA valve has split at the T with the return hose from the regulator. Are these two hoses all supplied as one unit, or is the T piece supposed to be servicable? There are no clamps on the hoses, so I suspect it is all one sealed unit.

I think Citroen use either green or blue for water temp guages on the connectors. I know it's not the same, but on my Xsara I had a simalar problem. Temp plugs both with green connectors but with brown wiring plugs. Did the easiest thing and stared the car and took each one off in turn. Can confirm though that both sensor for guage and fan is the same, main delaer told me this when I ordered mine.
I didn't even see the blue sensor yesterday. Is it on the end of the head near the water pipes?
Is the guage sensor interchangable with the fan sensor (as previously reported)? The replacement I have is part number 133866. The part is marked TJ 259/0 (the last digit is a bit unclear)
BTW, the inlet manifold gasket that needs to be replaced when changing the spark plugs was only £1.60 from the dealer. Was that a mistake?

I was replacing the temperature guage sensor because I thought that the temperature guage was usually reading about 10° lower than the thermostat temperature. I replaced the thermostat a few months ago with no change in guage readings.
But thinking about it now, if the sensor is in the head rather than by the thermostat, then the reading may well be lower than the thermostat temperature, due to cold water entering the engine from the radiator.
The temperatures I see are around 70° on a cold day, or any time that the A/C is on, and about 80° on a hot day with the A/C off (when the temperature is being regulated by the Bitron, rather than the water thermostat).
So what guage temperature do other V6 drivers see?
