A/C COMPRESSORM2551001100268
HIGH EFFICIENCY COMPRESSOR WITH
INTEGRATED OIL SEPARATOR
High efficiency compressor with integrated oil sepa-
rator has been adopted to enhance fuel economy by
reducing the A/C operating rate.
MAGNETIC CLUTCH WITH THERMAL
FUSE
At the compressor lock, the thermal fuse integrated
in the magnet clutch is blown due to the frictional
heat against the compressor in order to reduce risk
of the drive belt breakage. The thermal fuse, together
with the coil, is coated with resin to enhance resis
-
tance to corrosion.
2-STEP PROFILE COMPRESSOR
The centre area of the scroll in the compressor pro-
vides 2-step profile, and thickness of area "B" shown
in the figure has been increased to enhance
strength. With this feature, thickness of area "A"
shown where lesser load is applied is reduced, thus
compressor performance is enhanced by compress
-
ing refrigerant even in central area, comparing to the
previous model.
CONDENSERM2551001400140
The condenser has been integrated with the radiator (cooling
module) to optimise ventilation and reduce weight.

AIR DUCT AND AIR CLEANERM2150004000656
A front air intake system that actively sucks cooling
air from the front through the top of the radiator has
been adopted in order to improve engine perfor
-

GENERAL INFORMATION
ENGINE COOLING14-2
GENERAL INFORMATIONM2140000100780
The cooling system is a water-cooled pressurized,
forced circulation type which offers the following fea
-
tures.
•To stabilize engine coolant temperature, the ther-
mostat is located at the coolant inlet port from the
radiator.
•To improve engine cooling performance and save
weight, a plastic tank and aluminum radiator fins
are used.
