OE NO.:  30668628

Applicable vehicle type: For Vol vo

The car transmission cooler tube (also known as the transmission oil cooler tube or ATF cooler) is a key thermal management component in the automotive powertrain system. It is primarily used to control the operating temperature of automatic transmission fluid (ATF), ensuring stable operation of the transmission within the ideal temperature range of 80°C to 93°C. This product prevents issues such as reduced oil viscosity, lubrication failure, sludge formation, and seal aging caused by overheating of the oil through efficient heat exchange. Consequently, it extends the service life of the transmission, guarantees smooth shifting, and maintains transmission efficiency.

Maintenance and Servicing

• Regular Inspection: Check pipe joints for leaks every 20,000 kilometers.
• Replacement Cycle: It is recommended to replace it synchronously with the transmission oil (40,000-60,000 kilometers).
• Cleaning Radiator: Wind-cooled products require regular cleaning of dust and oil stains.
• Coolant Maintenance: Ensure the quality of the engine coolant to prevent clogging of the heat exchanger.
• Fault Warning: Immediate inspection is required when gear shifting jolts or oil temperature alarm occurs.
