The symptoms were it overheated and coolant keeps getting pushed out from the radiator filler. After 2018 when the Head was replaced, the coolant is still pushing out from the radiator. Although however, it does not overheat. This then cause me to refill the coolant once a week.

I was told that this is a common problem for ZD30DDTI.

What should I do to overcome this problem? Is there a solution for this?
Take it back to who ever changed the head and told you it was right. It’s not right.
