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.

Engine Coolant Protection Inspection
1. Measure the engine coolant temperature and specific gravity using a thermometer
and a hydrometer.
CAUTION:
Use engine coolant at a concentration that meets the environmental conditions
in which the vehicle is driven, otherwise engine damage could occur.
