System Operation
Engine coolant flows primarily from the engine to the radiator circuit
and back to the coolant pump. Coolant is sent from the coolant pump
through the engine block and cylinder head. A separate circuit from the
engine also feeds the heater core and turbocharger with coolant. The
coolant pump, operated by engine rotation through the accessory drive
belt, circulates the ..
