Automatic Transmission Radiator for Audi A4 S4 A6 S6 with Oil Cooler
Automatic-transmission engine cooling radiator for selected Audi A4, S4, A6 and S6 models. It features a 632 × 398 × 32 mm aluminum core, plastic water tanks and an integrated Φ22 × 300 mm transmission oil cooler and cross-references OE numbers 8D0121251L and 8D0121251BB.
1. Vehicle Fitment and Part Identification
The KU-FV-04-003 engine cooling radiator is designed for selected Audi A4 and S4 automatic-transmission models from 1994 onward and selected Audi A6 and S6 automatic-transmission models from 1997 onward.
It cross-references OE numbers 8D0121251L and 8D0121251BB. Buyers should verify the OE number, VIN, engine specification and transmission configuration before ordering.
2. Engine and Transmission Cooling
• Integrated Transmission Oil Cooler: The built-in Φ22 × 300 mm oil cooler supports heat management for the automatic transmission fluid.
• Combined Thermal Management: The radiator supports engine coolant heat dissipation while providing a separate cooling path for the transmission oil.
• 32 mm Core Thickness: Provides an effective heat-transfer surface within the corresponding original installation area.
• Automatic-Transmission Configuration: Designed for compatible vehicles requiring radiator-mounted transmission oil cooling connections.
3. Cooling Core and Tank Construction
• Aluminum Cooling Core: Transfers heat from the engine coolant to the surrounding airflow.
• Dense Cooling Fin Layout: Increases the available surface area for efficient heat exchange.
• Plastic Water Tanks: Provide a practical combination of structural strength, reduced weight and corrosion resistance.
• Vehicle-Specific Connections: The inlet, outlet, mounting points and oil cooler fittings are configured for the corresponding vehicle applications.
4. Replacement and Procurement Benefits
• OE-Referenced Configuration: Developed around the listed OE numbers and corresponding cooling-system layout.
• Replacement Application: Suitable for replacing an aged, leaking, blocked or inefficient original radiator.
• Integrated Oil Cooling: Eliminates the need for a separate internal transmission cooler within the specified installation configuration.
• Workshop Installation: Designed for professional installation using the corresponding mounting position and system connections.
• B2B Distribution: Suitable for automotive parts importers, wholesalers, distributors and repair workshops.
