I have had my coolant system tested at two different shops and both said I have a small external coolant leak on the back of the engine, either the intake or the head gasket. Today a cadillac mechanic told me he believes it would be an engine oil cooler. I am having an oil pressure problem also. Can you tell me what the symptoms of engine oil cooler vs. head gasket are? 108,000 miles on it.
