60 and radiator 65 the direction of arrows 69 indicates the effect of fan 68 on air intake note however that the direction of the fan is to some extent arbitrary and it may blow in the other direction the arrow 70 indicates the direction of air flowing into the front of a vehicle air flow indicated by arrow 70 is also delivered through spacer 63 to the radiator 65 where it provides a similar cooling function for fluids circulating through the engine and passenger compartment a coolant input 66 and coolant output 67 are indicated to illustrate flow of coolants through the radiator 65 this configuration permits the cooling air flow 70 to provide adequate cooling to turbocharged heated air at aftercooler 60 and to coolant circulating through the engine 90 and passenger compartment of the vehicle referring to fig4 a perspective expanded view of the after cooler radiator assembly 10 of the preferred embodiment is shown the aftercooler 60 as described with respect to fig3 is represented generally by a three dimensional block the frame of the radiator assembly 65 is also illustrated located between the after cooler 60 and the radiator 65 is a cooling system spacer 63 as discussed with respect to fig3 the spacer 63 permits the aftercooler 60 and radiator 65 to be in a serial arrangement for receiving inflow air while at the same time.
