Over the last few years, due to trends in styling, many newer cars do not have conventional grills up front. Very often, a closed panel resides, or the hood extends down to where a grill would have been. But all vehicles still depend on air passing through the radiator to provide engine cooling, and also for A/C system operation.
Many vehicles now have electric cooling fans that do not operate until necessary, when the engine coolant temperature climbs above a certain point.
The heater core is located inside the passenger compartment of the vehicle, quite often very deeply buried inside or under the instrument panel, or behind some other type of interior trim panel. Some SUVs and vans have two heater cores, a front and a rear.
A radiator has 2 tanks, one containing the inlet and one containing the outlet. These tanks, which can be at the top and bottom or sides, are usually made of aluminum, brass, copper, or plastic (most newer vehicles use the plastic type).

/C system odors typically result from uncontrolled growth of bacteria and other microorganisms in the evaporator part. Nasty little beasts like aspergillus, cladesporium and penicillium grow on cooling coils and other areas. How do these beasts get there?
They are naturally present in outdoor air and are drawn into the system through the evaporator during system operation.
