    I'm not following you - coolant loss at the coil on plug? How do you mean?

    I'm sorry; I need more information. I know all about this engine, and can not determine what you mean about "coil insert". 8 coils go down into the engine and cover the spark plugs. Do you mean that coolant is getting into those holes from a leaking hose or something? This was an issue at the heater core hoses and the number 4 coil many years ago - is this what you are describing? There are no actual coolant passages in the holes that go to the spark plugs, for example... Help me understand.
