Honda Acura NSX 1991 Service Manual page 59

The radiator, made of aluminum alloy, is mounted in the front of the vehicle to gain maximum cooling efficiency from air
passage. It is a corrugated-fin type, double row alminum core radiator with electric cooling fan. Since the tubes are in a
line, the volume of the cooling water in the radiator is reduced for less weight. The upper and lower tanks are made of
resinous material for reduced weight and increased corrosion protection.
The engine compartment cooling fan is mounted on the right side. It operates in conjunction with the radiator's electric
cooling fan in high mode.
The expansion tank is used to separate air out of the coolant circulating through the system.
