Product Details

CSF 3346 is part of the brand’s 1 Row Plastic Tank Aluminum Core line, which focuses on OE-style radiator construction for common passenger vehicles. CSF manufactures a wide range of radiator models and states that its products are engineered and validated for cooling performance in laboratory testing. For Nissan Sentra owners needing a direct-fit radiator replacement, this unit follows the original-style plastic tank and aluminum core format used in many factory cooling systems.

This part cross-references APDI 8012998 and Spectra Premium CU2998 for the same application. The CSF 3346 radiator is a practical choice for Sentra cooling system repair when the original radiator shows signs of leakage, restricted flow, or age-related wear.

Common Cooling System Issues

• Coolant leaks from cracked or aged radiator tanks
• Overheating caused by reduced heat transfer through the core
• Cooling performance loss from internal blockage or corrosion
• Damaged inlet or outlet connections on the original radiator
• Replacement needed after impact or long-term thermal cycling

Installation Notes

Verify radiator dimensions, inlet and outlet orientation, and mounting points before installation. This radiator uses a down-flow layout and left-side inlet/outlet placement, so matching the original configuration is important for proper fit. Transfer any required vehicle-specific components from the original assembly as needed, and confirm the correct cap specification before filling and bleeding the cooling system.

Quality Assurance

CSF states that its factories are ISO/TSO certified and that its radiators are built to high-performance standards. The brand also notes long-term global production experience and wind-tunnel testing used to validate cooling performance.
