CSF 3429 Radiator for Mini Cooper Applications

The CSF 3429 is an OE-style radiator built with a plastic tank and aluminum core for Mini Cooper cooling system service. It is engineered for direct-fit replacement in select Mini Cooper, Cooper Countryman, and Cooper Paceman applications, with cross-flow construction and factory-style inlet and outlet placement.

Key Features

  • OE-style plastic tank and aluminum core construction
  • Cross-flow radiator design
  • 1-row core with 5/8 in. thickness
  • Left inlet and right outlet configuration
  • Core dimensions: 23 5/8 in. length and 16 5/16 in. width
  • Built to replace lower-performance mechanical-core designs with a brazed aluminum core
  • CSF part number 3429

Product Details

CSF designs and manufactures radiators to high-performance standards using lab validation and wind-tunnel testing for cooling performance. The 3429 radiator follows an OE-style layout with plastic tanks and an aluminum core, making it a direct replacement choice for Mini Cooper cooling system repair. This CSF 3429 radiator is listed for 2007-2016 Mini Cooper, 2011-2016 Mini Cooper Countryman, and 2013-2016 Mini Cooper Paceman applications, with fitment varying by model year. This part cross-references Spectra Premium CU13167 for the same application.

Common Cooling System Issues It Can Address

  • Coolant leaks from aging radiator tanks or core seams
  • Overheating caused by restricted or inefficient heat transfer
  • Temperature fluctuation from a worn factory radiator
  • Cooling performance loss after corrosion or internal buildup
  • Replacement needs after radiator damage or cracking

Installation Notes and Tips

Verify the inlet and outlet orientation before installation: inlet is 1 3/8 in. on the left and outlet is 1 3/8 in. on the right. Confirm vehicle year and model against the fitment list before ordering, especially for Mini Cooper, Cooper Countryman, and Cooper Paceman applications. The radiator is supplied without a cap, so reuse or replace the cap as needed based on the vehicle’s cooling system specification. CSF part number 3429 should be matched to the exact application and OE-style dimensions for proper fit.

Quality Assurance

CSF manufactures radiators in ISO/TSO-certified facilities and has supplied cooling products worldwide for more than 50 years. The brand reports over 30 million units sold and uses engineering validation methods to support cooling performance consistency across its radiator lineup.
