Detailed Description

CSF 3721 is engineered as a radiator and A/C condenser assembly for vehicles that use a compact front-end cooling package. The all-aluminum core and tanks help maintain a lightweight, corrosion-resistant design, while the cross-flow configuration supports efficient heat transfer in a factory-style layout. This part number is commonly searched as a Nissan 370Z radiator and condenser module, as well as an INFINITI G37 radiator assembly replacement.

CSF’s product line focuses on high-performance cooling components developed from extensive manufacturing experience and laboratory validation. For shoppers comparing CSF 3721 against OE-style replacements, this module is built to match the application-specific packaging used on the listed Nissan and INFINITI models, including 2007-2008 INFINITI G35, 2008-2013 INFINITI G37, 2011-2012 INFINITI G25, 2014-2015 INFINITI Q60, 2015 INFINITI Q40, and 2009-2020 Nissan 370Z.

This part cross-references Global Parts Distributors LLC 13004 for the same application.
