CSF High-Performance All-Aluminum Radiator — Porsche 911 (992 / 992.2), Left

A position-specific, all-aluminum replacement radiator engineered by CSF for verified Porsche 911 992 and 992.2 cooling-system applications.

Vehicle fitment

CSF publishes this position-specific radiator for selected Porsche 911 992 and 992.2 applications from model years 2019–2026. The manufacturer's application table includes:

• Selected 992.1 Carrera, Carrera 4, Carrera S, Carrera 4S, Carrera T, Carrera GTS, Carrera 4 GTS, and Targa branches through model year 2024.
• Selected 992.2 Carrera, Carrera S, Carrera T, Carrera 4S, Targa 4, and Targa 4S branches for model years 2025–2026.
• Selected 992.2 3.6-liter hybrid GTS, Carrera 4 GTS, and Targa 4 GTS branches for model years 2025–2026.
• Selected Sport Classic, Turbo, Turbo S, Turbo 50 Years, S/T, GT3, GT3 Touring, and GT3 Cup applications within CSF's published model-year table.

GT3 RS is explicitly excluded. CSF's source table contains several atypical generation/year labels, so fitment is not universal within these model families. EuroCustomsPR must confirm VIN, model year, trim, body style, equipment, radiator position, and the applicable Porsche OE reference before fulfillment.

Key benefits

• Position-specific replacement for the factory left radiator on supported vehicles.
• All-aluminum, TIG-welded construction with CNC-machined brackets and factory-style connections.
• CSF's two-row 42 mm B-tube core and 5 mm multi-louvered fins increase cooling surface area.
• CSF publishes an increase of up to 25% in heat transfer compared with the factory design; this is a manufacturer statement, not a EuroCustomsPR dyno or track-test claim.

• Published tube and fin count: 52 tubes and 53 fin rows.
• Fin specification: 5 mm multi-louvered fins.
• Construction: all-aluminum, TIG welded, pressure and leak tested.

What is included

One CSF Left radiator, part 7241. CSF does not publish a separate loose-hardware list for this product; hoses, coolant, clamps, fasteners, ducts, seals, tools, and installation labor should not be assumed included.

Required and recommended supporting components

Inspect the existing coolant hoses, clamps, mounts, seals, ducts, debris screens, and adjacent radiators before installation. Replace damaged or age-affected factory components and use the correct Porsche-approved coolant and current service procedure. Pairing 7241 with the opposite-side CSF 7242 radiator may be appropriate for a balanced cooling refresh, but each position is sold separately.

Installation notes

Installation requires front-body access, coolant-system draining and refilling, correct hose and duct positioning, leak testing, and complete cooling-system bleeding. Follow current Porsche and CSF procedures. Confirm that the vehicle already uses the matching left-side radiator and OE reference before disassembly.

Tuning, coding, and calibration

No ECU tune or coding is represented as required for a direct radiator replacement. Diagnostic checks and cooling-system service procedures may still be required.
