Product Description

The CSF 2997 is an OEM replacement radiator engineered specifically for the 2003-2006 Nissan 350Z equipped with the VQ35DE 3.5L V6 engine. This direct-fit radiator maintains factory cooling performance with its single-row aluminum core and plastic tank construction, matching the original equipment design for seamless installation. The integrated high-efficiency concentric type transmission oil cooler ensures proper ATF cooling for automatic transmission models, while manual transmission vehicles benefit from the same reliable fitment. CSF manufactures this radiator in ISO-certified facilities using rigorous quality control including hydrostatic testing, vibration cycle testing, thermal cycle testing, and burst pressure testing. The multi-louvered fin design maximizes heat dissipation, and all components are assembled, torqued, and tested during production. Backed by CSF's 2-Year Limited Warranty and over 40 million cooling systems sold worldwide.
