TRQ Radiator Dual Cooling Fan Assembly Compatible with 2003-2007

In this review the TRQ Radiator Dual Cooling Fan Assembly is examined as a direct replacement for 2003-2007 Infiniti G35 and 2003-2006 Nissan 350Z models; it is aimed at DIYers and independent shops who want a ready-to-install cooling solution. The bottom line: this assembly offers precise fitment and straightforward installation as a pre-assembled unit, making it a practical swap for overheating or failed fans. For anyone who values fit, function, and a clear install path, this is worth considering, though wiring variations and long-term durability merit a closer look.

Key Features

• Direct fit replacement: Pre-assembled dual radiator and condenser fans are designed to match original equipment dimensions for a straightforward swap without modification.
• Multiple reference compatibility: Lists reference numbers such as 21481CD000 and NI3115127 so users can confirm fitment against factory part numbers.
• Dual fan design: Two fans provide balanced airflow across the radiator and condenser to help maintain proper engine temperature under load.
• DIY support: TRQ provides a large catalog of DIY videos and guidance to help users complete the installation correctly the first time.
• Pre-wired assembly: Comes as an assembled unit to reduce installation time and effort compared with installing individual components.
• Compatibility notes: Clear compatibility callouts prompt buyers to verify fitment before ordering to avoid connector or mounting surprises.

Who It's For

This assembly is best for mechanics, hobbyist DIYers, and owners of 2003-2007 Infiniti G35 or 2003-2006 Nissan 350Z who need a direct-fit replacement and prefer a pre-assembled unit to save time. It suits those who want clear reference numbers to match against their OEM parts and who appreciate video guidance during installation.

It may be less ideal for owners who require an OE-branded part with manufacturer warranty specifics or for vehicles with aftermarket wiring modifications; some buyers reported mixed wiring connectors and one concern about long-term durability, so those needing dealer-level assurances should consider that before purchase.
