[2]  BOTTOM BYPASS SYSTEM

In addition to improving the cooling performance of

the  radiator  by  utilizing  a  bottom  bypass  system,  the

mechanism  uses  a  3-stage  thermostat  valve  that

reduces  thermal  shock  considerably  compared  to

previous radiators.

When  the  coolant  inside  the  engine  is  cool,  the

thermostat (4) stays closed and coolant circulates inside

the engine via the bypass pipe.

When  the  temperature  of  the  coolant  exceeds  the

opening  temperature  of  the  thermostat  (4),  the

thermostat opens in three stages, sending the now hot

coolant to the radiator. Further, when the thermostat is

fully open, it is structured so the hot coolant does not flow

into the engine via the bypass circuit, thus increasing the

cooling performance of the system.
