General Coolant leak, 1990 Ducato.

[Dadsowdvan]

Hi all. I have a1990 Ducato camper, 1.9 petrol. There is a coolant leak through a coroded 3 way pipe connector that needs replacing. It actually looks like a four way connector but one of the outlets has a sensor connected to it. Im guessing its a water temp thing. Pic attached. Any idea where I would finda replacement? Or should I just ignore the sensor? Thanks.

From Wikipedia it seems that you engine will be a PSA170 series engine, so perhaps you may be able to widen your search to include those makes. (Citroen and Peugeot.)
If the sensor has only a single wire, as visible in the photo, then it is likely to be for a temperature gauge.
