ABSTRACT:
A turbocharged engine cooling system has separate, complete engine and aftercooler coolant loops connected by a linking conduit with a link valve and a fan apparatus providing air flow through both engine and aftercooler radiators. The fan apparatus is controllable to vary the air flow in a series of discrete cooling levels. An engine cooling control is responsive to a coolant temperature in the engine coolant loop to control the fan apparatus and to derive and output a signal indicative of a desired level of cooling between the selected one and an adjacent one of the discrete cooling levels. An aftercooler cooling control is responsive to a coolant temperature in the aftercooler coolant loop and the signal output by the engine cooling control to control the link valve so as to vary the temperature of coolant in the engine cooling loop, by controlled mixing of coolant of lower temperature from the aftercooler cooling loop, so as to achieve the desired level of cooling indicated by the signal.
