Automatic transmission cooling pipes for Mercedes-Benz W203
Automatic transmission cooler pipes are an integral part of the transmission cooling system, which removes heat from the automatic transmission (AT). The Mercedes-Benz W203 uses the following types of automatic transmission cooling pipes:
Automatic transmission cooling pipe from the radiator
* Connects the automatic transmission heat exchanger to the radiator, allowing the heat transfer fluid to circulate and cool.
* Parts: A 203 201 03 82
Automatic transmission cooling return pipe
* Connects the automatic transmission heat exchanger to the automatic transmission housing, allowing heat transfer fluid to return to the transmission.
* Parts: A 203 201 04 82
Automatic transmission cooling pipe laying
* Provides a sealed connection between cooling pipes and related components.
* Parts: A 203 201 01 10 (x4)
Automatic transmission cooling pipe clamps
* Secures cooling tubes in place and prevents leaks.
* Parts: A 000 030 11 17 (x4)
Replacing automatic transmission cooling pipes
If leaks, damage, or blockages occur, the transmission coolant pipes may need to be replaced. Here are the general steps for replacement:
1. Raise and secure the vehicle.
2. Drain the automatic transmission fluid.
3. Disconnect the electrical connector from the automatic transmission heat exchanger.
4. Remove the bolts securing the cooling pipes to the radiator and automatic transmission housing.
5. Remove the old cooling tubes.
6. Install new cooling pipes using new gaskets and clamps.
7. Connect the electrical connector to the automatic transmission heat exchanger.
8. Fill with automatic transmission fluid.
9. Check for leaks and proper operation of the cooling system.
Signs of the need to replace automatic transmission coolant pipes
* Transmission fluid leaks
* Automatic transmission overheating
*Transmission slipping
* Burning smell
It is important to regularly inspect and maintain transmission cooler lines and other transmission cooling system components to ensure trouble-free operation of the transmission and prevent costly breakdowns.
