sounds like a blown head gasket. You will need to remove the glow plugs and crank the engine over while having someone watch for coolant mist from the holes.
When replacing the head gaskets, take the old ones to the parts store so they can be matched up. There are a few different thickness gaskets used on the D-MAX.
