Abstract: A coolant control system of a vehicle includes an opening module configured to determine a coolant valve (CV) opening, a flow control valve (FCV) opening, and a block valve (BV) opening based on at least one of a block temperature difference, a head temperature difference, and a coolant outlet temperature difference. A CV control module is configured to selectively actuate a CV based on the CV opening. The CV regulates coolant flow from the FCV to a radiator and a coolant channel bypassing the radiator. A BV control module is configured to selectively actuate a BV based on the BV opening. The BV regulates coolant flow from the engine block to the FCV. A FCV control module is configured to selectively actuate a FCV based on the FCV opening. The FCV regulates coolant flow from the cylinder head and the BV to the CV.
