Component Description

A/T fluid warmer

• A/T fluid warmer (1) is mounted at the front part right side of cylinder block of engine.
• When engine is started while engine and A/T are cold, engine coolant temperature rises more quickly than A/T fluid temperature. A/T fluid warmer is provided with two circuits for ATF and engine coolant respectively so that warmed engine coolant warms ATF quickly. This helps shorten A/T warming up time, improving fuel economy.
• This unit has a cooling effect, as a water-cooled cooler, on the ATF when A/T fluid temperature is high.
