UUTLlNE OF CONSTRUCTtON
The BP SOHC engine for the 4WD model is the same as for the 2WD model, except that the flywheel is
shaped differently.
The 3P SOHC engine for the ECE specification (without catatyst) 4WD model is the same as the ECE US83
model, except that the fuel and emission control system and the engine electrical system are modified.

BUTLINE OF CONSTRUCTION
The
lubrication system of the 323 4WD engine is the same as for the 2WD model.
The Bf DOHC turbocharged engine oil circulation path is different than that of the BP DOtiC non-turbocharged
engine
because of the turbocharger lubrication.

OUTttNE OF CONSTRUCTION
The cooling system in the 323 4WD model is basically the same as in the 323 2WD model.
Although there is no fundamental change from the BP DOHC of the 2WD model, the coolant circulation
path has been changed to direct coolant to the water-cooied turbocharger.
A two-stage thermostat is used in the BP DUHC turbocharged engine to stabilize the engine coolant tem-
peratu re.
The radiator and cooling fan specifications are different. The BP DOHC turbocharged engine of the 4WD
model uses a two-speed electric cooling fan.

The fuel and emission control systems of the New 3.23 BP SOHC-engine equipped 4WD model are basically
the same as those of the New 323 8P DOHC-engine equipped 2WD model, however, the fuel tank is designed
with separate right
and left sections due to the installation of the propeller shaft for the 4-wheel-drive system
and
a transfer pump is equipped to pump the fuel from the left to the right (fuei pump side) section of the
fue! tank. The following chart shows the differences between the major parts of the BP DO% 2WD model
and the BP SOHC 4WD model.

OUTLINE OF CONSTRUCTION
The fuel and emission control system of the new 323 4WD model is basically the same as that of the new
323 2WD modet; however, a turbocharger and knock control system are added to the BP TURBO model
and the fuel tank is designed
with separate right and left sections due to the installation of the propeller shaft
for the 4-wheel-drive system. A transfer pump is also equipped to pump the fuel from the left
to the right
(fuel pump side) section of the fuel tank.
The major points of difference between the 2WD model and 4WD model are as shown below.
