Subaru automatic transmission oil cooling system
The automatic transmission oil cooling system is designed to maintain the optimal operating temperature of the automatic transmission oil, which is necessary to ensure smooth and efficient operation of the transmission.
Subaru automatic transmission oil cooling system components:
* Oil/water heat exchanger: Built into the engine radiator. Allows cooling of automatic transmission oil due to the circulation of engine coolant.
* Oil line: Connects the heat exchanger to the automatic transmission, transporting oil between them.
* Oil filter: Cleans the oil from impurities, protecting the automatic transmission from wear.
* Oil system thermostat: Regulates the flow of coolant through the oil/water heat exchanger, preventing overheating or undercooling of the automatic transmission oil.
Working principle:
1. Automatic transmission oil circulates through an oil/water heat exchanger, where it transfers heat to the engine coolant.
2. Cooled oil returns to the automatic transmission.
3. The oil system thermostat monitors the temperature of the automatic transmission oil and regulates the flow of coolant through the heat exchanger, maintaining the optimal operating temperature.
Advantages:
* Improved efficiency: Automatic transmission oil cooling reduces friction losses, improving fuel economy and performance.
* Reduced wear: Reducing automatic transmission oil temperature extends transmission life by reducing component wear.
* Smooth gear shifting: Optimal automatic transmission oil temperature ensures smooth gear shifting and prevents delays or jerks.
Maintenance:
* Regular replacement of automatic transmission oil and filter.
* Checking the coolant level.
* Flushing the oil/water heat exchanger in case of clogging.
* Diagnose faults using a fault code scanner.
