OE-Style Cooling Replacement for Audi and Volkswagen
The CSF 3361 radiator is an OE-style replacement built with a 1-row aluminum core and plastic tanks for select Audi and Volkswagen applications. It is engineered for direct-fit cooling performance in vehicles such as the Audi A4, Audi A4 Quattro, Audi A6, Audi A6 Quattro, and Volkswagen Passat.
CSF manufactures radiators to high-performance standards, with production backed by ISO/TSO-certified factories and validation testing focused on cooling efficiency. The CSF 3361 uses a cross-flow design with quick-connect inlet and outlet pipes for a factory-style service replacement.
Key Features
- 1-row aluminum core with plastic tanks
- Cross-flow radiator design
- Core thickness: 1 1/4 in.
- Core width: 15 11/16 in.; core length: 24 13/16 in.
- Inlet diameter: 1 1/4 left; outlet diameter: 1 1/4 right
- O.E.M.-style plastic tanks and aluminum core construction
- Steel crimps used to strengthen the radiator assembly
- High-efficiency plate-type oil cooler section
Detailed Description
CSF part number 3361 is designed for drivers replacing a worn or leaking radiator in 1996-2001 Audi A4, 1996-2001 Audi A4 Quattro, 1998-2001 Audi A6, 1998-2001 Audi A6 Quattro, and 1998-2005 Volkswagen Passat models. The OE-style layout helps maintain factory routing and fitment, while the aluminum core supports efficient heat transfer and the plastic tank construction matches the original-style design used in these vehicles. This part cross-references Spectra Premium CU2648 for the same application.
CSF has supplied radiators worldwide for decades and manufactures a broad range of cooling products for many vehicle platforms. The 3361 reflects that experience with a direct-fit configuration intended for routine radiator replacement on Audi A4, Audi A6, and Volkswagen Passat cooling systems.
Common Problems This Radiator Can Address
- Coolant leaks from cracked or aged radiator tanks
- Restricted cooling performance from a clogged or corroded core
- Overheating caused by reduced heat dissipation
- Damaged inlet or outlet connections
- Service replacement after radiator failure on Audi A4, Audi A6, or Volkswagen Passat models
Installation Notes and Tips
Verify inlet and outlet orientation before installation: inlet is on the left and outlet is on the right. This radiator uses quick-connect inlet and outlet pipe connections and does not include a cap. Confirm vehicle-specific fitment for your exact Audi A4, Audi A4 Quattro, Audi A6, Audi A6 Quattro, or Volkswagen Passat year before installation.
Quality Assurance
CSF radiators are produced in ISO/TSO-certified factories and are engineered with cooling performance validation in mind. The brand’s manufacturing experience and OE-style construction support consistent replacement quality for the CSF 3361 radiator.
