1990 Ducato coolant leak. (7 Viewers)

[Dadsowdvan]

Hi all. I have just started up my late dad's old campervan. It's a Ducato 1.9 petrol. There is a coolant leak coming from where a metal hose connector joins different pipes. This corroded part also has a sensor on it. I don't know what it's called and would appreciate any help so I can order a new on. Thanks in advance.

No idea but it is just a 4 way connector so all you really need is the internal pipe size, possibly 1/2" =12 or 13mm or 5/8" = around 15mm & find a plumbing fitting or irrigation in in steel or plastic.
It is very doubtful you would get anything from Fiat as 14 years is the life of their spare parts- You would have to look on Autodoc.uk or similar for a possible part

As for the sensor probably the only place that might have one would be coastal

The 'sensor' could be a diverter valve to divert water to different pipes....possibly the heater on/off control.
Simply unscrew it and put it in the new three way coupler.
