Nissan Murano: Structure and Operation / Fluid Cooler Fluid Warmer System
CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
-
The CVT oil warmer (1) is installed on the front part of transaxle assembly.
-
When engine is started while engine and CVT are cold, engine coolant temperature rises more quickly than CVT fluid temperature. CVT oil warmer is provided with two circuits for CVT and engine coolant respectively so that warmed engine coolant warms CVT quickly. This helps shorten CVT warming up time, improving fuel economy.
-
A cooling effect is obtained when CVT fluid temperature is high.
Heater Thermostat
-
The heater thermostat (1) is installed on the front part of transaxle assembly.
-
The heater thermostat open and close with set temperature.
