Purpose/Function
The oil cooler constantly maintains maximum ATF performance in the transaxle by maintaining an optimum ATF temperature which has the effect of achieving reduced fuel consumption.
Construction/Operation
The oil cooler performs the following operations according to the ATF temperature condition:
Heating function: Warms the ATF using the radiator coolant to promote an earlier increase in the ATF temperature when its temperature is low. As a result of the earlier temperature increase, the ATF viscosity decreases which reduces drag in the transaxle.
Cooling function: Cools the ATF using the radiator coolant to maintain optimum conditions and prevent ATF expansion and deterioration.
