Will you lose coolant if you have a blown head gasket?
Will you lose coolant if you have a blown head gasket? Not only does a blown head gasket mean oil and coolant can leak inside the engine, it can even allow coolant to get into the oil system where they'll mix together. Do you think it is Hg or loss of coolant? The interior heating is first the stop. When I take off the filler cap the empty tank starts refilling and shows it has enough water. Once I restart the engine, the heat is back and temperature back to normal. Oil colour and amount has never been a problem....
