The  cooling  system  is  a  water-cooled  pressurized,
forced  circulation  type  which  offers  the  following
features.

｠

To  stabilize  engine  coolant  temperature,  the
thermostat 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.

｠

Vehicles  for  California  emission  regulation:
PremAir®*  direct  ozone  reduction  (DOR)  radiator
has  been  adopted  to  protect  the  environment.  A
catalyst which reduces ozone (O3) in the ambient
air has been applied to the radiator core.
