Abstract

A method to operate a split coolant circuit of a combustion engine wherein a cylinder head coolant jacket and an engine block coolant jacket are provided in series with a pump delivering coolant to an inlet of the cylinder head coolant jacket without being directly connected to an inlet of the engine block coolant jacket. This allows for 100% of the pump flow rate to be delivered to the cylinder head coolant jacket before division of coolant flow occurs for various engine operating conditions.
