Toyota Corolla GR (2023-) CSF High-Performance Radiator

CSF High-Performance Radiator for Toyota GR Corolla & GR Yaris (Part No. 7233)

Description

Elevate your Toyota GR Corolla or GR Yaris’s cooling efficiency with the CSF High-Performance Radiator. Engineered for enthusiasts pushing their vehicles to the limit, this radiator addresses the shortcomings of the factory unit, ensuring optimal performance during spirited driving and track sessions.

Featuring a 2-row, 42mm core with CSF’s exclusive B-Tube Technology, this radiator offers approximately 15% more efficient heat transfer compared to standard designs. The 5mm tall multi-louvered fins maximize surface area contact, enhancing heat dissipation and ensuring consistent engine temperatures under load.

Constructed with 100% TIG-welded aluminum, including CNC-machined mounting brackets and OEM-style inlet/outlet, the radiator guarantees durability and a precise fit. The inclusion of a pre-plugged 1/8th NPT temperature sensor port and pre-installed foam strips further underscores its performance-oriented design.

  With aluminum end tanks replacing factory plastic, CSF’s construction resists fatigue, pressure, and heat better than OEM options.

• Plug-and-Play Fitment
  Engineered as a true drop-in replacement — no cutting, bending, or trimming required.
