Fuel consumption

The cause of inconvenience in BC7 SUBARU LSi US model has not specified yet, continuous cooling fan running after being once started. Uneven heat distribution on the radiator surface reveals that coolant flowing is not adequate, so as the the first step to measure this malfunction,  replacement of a thermostat parts on the motor built on just at adjacent portion of coolant lower hose. As the next step if an inconvenience is not removed, the temperature sensor transmitting an important signal to control A/F ratio would be replaced. Though some much fuel consumption is the fundamental designing by the manufacturer while while the passed Japanese Bubble Period, much fuel consumption might have been brought by the critical phase shift of the characteristics on the sensor, playing a great part of EGI system.
As the third step, replacement of ATF, from TOYOTA Castle genuine parts D2 to SUBARU CVT ATF.
In case the malfunction in transfer clutch would not disappear, disassembling of rear case and replacement of multi-clutch plates would be performed. The service schedules continues endlessly.
