6) Cooling Fan Control
(1) Overview of Cooling Fan and A/C Compressor
The cooling system maintains the engine temperature at an efficient level during all engine operating
conditions. The water pump draws the coolant from the radiator. The coolant then circulates through
water jackets in the engine block, the intake manifold, and the cylinder head. When the coolant reaches
the operating temperature of the thermostat, the thermostat opens. The coolant then goes back to the
radiator where it cools. The heat from automatic transaxle is also cooled down through the radiator by
circulating the oil through the oil pump. There are two cooling fans (180W+120W) in G20DF engine. ECU
controls the electric cooling fans with three cooling fan relays to improve the engine torque and air
conditioning performance.

ECU
Intercooler assemblyAir cleaner assembly

Swirl control valve
It operates variably in accordance with the
engine load and rpm.
Intake manifold
It is the passage for intake air when the swirl
vale is operating. The T-MAP sensor for
measuring the pressure and temperature of
pressurized air in turbocharger is installed on
the left top of intake manifold.
3. LAYOUT OF INTAKE SYSTEM
1) Overview
The intake system for D20DTF(Low CO2) engine is equipped with a throttle body which includes a flap.
This flap is controlled by an electrical signal to cut off the intake air entering to the engine when the
ignition switch is turned off. The intake manifold contains the swirl control valve and dual port system to
make the optimum turbulence. The T-MAP sensor is located on the left top of the intake manifold and
the HFM sensor for precise control is located at the rear side of air cleaner. To reduce the intake noise
and to improve the intake efficiency, the volume of air cleaner has been increased.
