Toyota Highlander automatic transmission cooling radiator
The automatic transmission cooler is an important component of the Toyota Highlander transmission. It helps remove heat from the transmission fluid, preventing it from overheating and damaging automatic transmission components.
Location
The Toyota Highlander automatic transmission cooling radiator is located in front of the main engine radiator. It is attached to the bottom of the main radiator and is cooled by air flow through the grille.
Design
The automatic transmission cooling radiator is a small tubular heat exchanger. Transmission fluid circulates through the tubes and air flows around them, dissipating heat.
Functions
* Heat Dissipation: The radiator removes heat from the transmission fluid, preventing it from overheating.
* Maintain Optimal Temperature: The radiator helps maintain the optimal operating temperature of the transmission fluid, ensuring smooth and efficient operation of the automatic transmission.
Signs of malfunction
Some signs of a faulty automatic transmission cooler include:
*Transmission fluid leak
* Automatic transmission overheating
* Automatic transmission slipping
* Noise or vibration when shifting gears
Replacement
If the automatic transmission cooling radiator is faulty, it must be replaced. To do this you need:
1. Drain the transmission fluid.
2. Disconnect the transmission fluid hoses from the radiator.
3. Remove the radiator from the main radiator.
4. Install a new radiator and connect the hoses.
5. Fill in new transmission fluid.
Prevention
To prevent malfunctions of the automatic transmission radiator, it is important:
* Change the transmission fluid and filter regularly.
* Check the transmission fluid level.
* Avoid overloading and slipping.
* Flush the automatic transmission cooling radiator every 60,000-90,000 km.
