Hi guys.
I need help solving this problem of mine.
My van started leaking coolant really fast. The problem seems to be from this aluminium part on the right hand side of the crankshaft between the fuel filter and the thermostat housing. I had a quick look at the thermostat and the hoses around it and they all seem fine but whatever it is it seems to be a huge leak as it looses all the water in a matter of minutes now. The leak seems to be coming from the bottom corner of that aluminium part that I can't seem to identify. One of the images is from the top and the other from the bottom.The water pump has been replaced last month so I think this isn't a related issue.
The van is a sprinter 313 2010 reg. Can anyone advise on what the problem might be
