Automatic transmission cooling system Nissan Almera
The automatic transmission cooling system in the Nissan Almera is designed to remove heat from the transmission, preventing overheating and subsequent damage.
Automatic transmission cooling system components:
* Oil Cooler: A tubular heat exchanger that cools transmission fluid by passing it through tubes surrounded by coolant.
* Thermostat: Regulates the flow of transmission fluid through the oil cooler, opening when the set temperature is reached.
* Automatic transmission oil pump: Creates transmission fluid pressure to supply automatic transmission components and the oil cooler.
* Tubes and hoses: Connect the components of the automatic transmission cooling system.
Operating principle of the automatic transmission cooling system:
* Transmission fluid heats up during automatic transmission operation.
* The automatic transmission pump pumps heated fluid through the thermostat.
*If the fluid temperature reaches operating temperature, the thermostat opens, allowing fluid to circulate through the oil cooler.
* The oil cooler transfers heat from the transmission fluid to the coolant.
* The cooled transmission fluid is returned to the automatic transmission.
Automatic transmission cooling system maintenance:
To ensure optimal operation of the automatic transmission cooling system, it is important to regularly perform the following actions:
*Check the transmission fluid level and condition: Low levels or contaminated fluid may impair cooling.
* Replace transmission fluid according to the manufacturer’s recommendations: Old fluid loses its cooling properties.
* Check the thermostat: A faulty thermostat can cause the automatic transmission to overheat or underheat.
* Inspect hoses and tubes: Cuts or cracks can cause transmission fluid leaks and reduce cooling.
* Clean the oil cooler regularly: A dirty radiator will reduce cooling efficiency.
