Abstract
A coolant control system of a vehicle includes a fraction module, and a coolant valve control module. The fraction module determines an oil fuel fraction based on an amount of fuel in an amount of engine oil. The coolant valve control module, based on the oil fuel fraction, selectively actuates a coolant valve to enable coolant flow from an integrated exhaust manifold (IEM) of an engine to an engine oil heat exchanger.
