CSF Radiator 42mm 2 Row Aluminum Core Ford Fiesta ST 14-19

Cooling the engine, the CSF Radiator 42mm 2-Row Aluminum Core for Ford Fiesta ST 14-19 delivers a measurable increase in heat absorption and dissipation, improving thermal management and reliability under sustained load.

Designed by CSF, this 42mm 2-row aluminum core replaces the factory unit with a thicker core and an additional cooling row to expand heat capacity without changing the external packaging.

• Thicker 42mm core — increases coolant volume and thermal mass, allowing the system to absorb more heat before peak temperatures are reached.
• Two-row construction — provides more cooling surface area than a single-row core, which improves heat rejection to ambient air during continuous highway or track use.
• Increased fluid capacity — raises the total coolant volume in the system to reduce temperature rise under sustained high-load conditions.
• CSF Exclusive B-Tube Technology — enhances internal heat transfer dynamics for more efficient coolant-to-tube heat exchange.
• Full aluminum construction — combines conductive metals for consistent thermal performance and corrosion-resistant properties appropriate for street and performance use.

Each feature focuses on improving the radiator’s core function: maintaining lower operating temperatures and reducing thermal stress on the engine and cooling system components during extended demanding operation.

CSF engineers this radiator as a direct-fit upgrade for the Ford Fiesta ST 2014–2019 platform, maintaining installation simplicity while delivering greater cooling capacity than the factory core.
