(1) Aftercooler
(2) Thermostatic valve
(3) Source of the coolant
(4) Separate circuit water pumpCoolant is pulled from the source of the coolant (3) through an elbow into separate circuit water pump (4). The coolant is pumped through aftercooler (1).Coolant flows from the aftercooler to thermostatic valve (2). Before the temperature of the coolant rises, the coolant is diverted to separate circuit water pump (4).When the temperature of the coolant increases enough to open the thermostatic valve, the path of the coolant flow changes. The coolant flow from the thermostatic valve to the water pump is restricted. Coolant is circulated back to the source of the coolant (3).
