Automatic transmission cooling system Nissan Pathfinder R51
The Nissan Pathfinder R51 automatic transmission cooling system is designed to dissipate the heat generated by the transmission during operation. This helps prevent overheating and damage to the automatic transmission.
Automatic transmission cooling system components:
* Automatic transmission radiator: Tubular radiator located in front of the main radiator.
*Automatic transmission cooling lines: Tubes connecting the automatic transmission radiator and automatic transmission.
* Automatic transmission pump: Circulates transmission fluid through the cooling system.
* Automatic transmission thermostat: Regulates the flow of transmission fluid through the automatic transmission radiator.
Working principle:
1. The automatic transmission pump circulates transmission fluid through the cooling system.
2. When the fluid heats up, the automatic transmission thermostat opens, allowing fluid to flow through the automatic transmission radiator.
3. Heat from the fluid is transferred to the automatic transmission radiator, and then to the air passing through it.
4. The cooled fluid returns to the automatic transmission.
Maintenance of the automatic transmission cooling system:
* Check the transmission fluid level regularly.
* Replace transmission fluid regularly.
* Flush the automatic transmission radiator and cooling lines as needed.
* Check the automatic transmission thermostat for proper operation.
Symptoms of problems with the automatic transmission cooling system:
* Automatic transmission overheating: The automatic transmission overheating indicator on the dashboard lights up.
* Gear slipping: The automatic transmission does not shift gears smoothly.
* Difficulty shifting gears: The automatic transmission does not shift gears consistently.
*Transmission fluid leaks: Inspect the transmission radiator and coolant lines for leaks.
Note: If you experience any of these symptoms, it is important to contact a qualified mechanic as soon as possible. Operating a vehicle with an overheated transmission can cause extensive damage and costly repairs.
