1.5D thermostat housing leak

  1. #1
    I'm losing coolant from the underside of my thermostat housing - not the plastic piece that the thermostat protrudes into - the actual metal housing that also has the temperature sensor going into it.

    The leak is coming from what feels like a recessed bolt on the underside (a spare probe port ?)

    Is there a way to take the entire housing off ? I can only see one bolt holding it to anything - a 10mm bolt near the fuel filter, surely there must be more.
