DWVO Radiator for Nissan Altima & Maxima — 2.5L/3.5L Direct OEM-Fit Aluminium Core, TIG-Welded Durability

DWVO complete radiator engineered as a direct OEM-fit replacement for Nissan Altima 2.5L (2007–2018) and Maxima 3.5L (2009–2023), delivering improved cooling reliability and a straightforward drop-in install.

If your Nissan is running hotter than it should, or you're replacing a damaged or corroded cooling core, this DWVO radiator matches the original equipment design to restore factory-fit performance. Built with a high-density aluminum core and reinforced tank connections, it’s intended to meet the shape, mounting points, and flow characteristics of the factory part numbers 21410zn50a and 21460zn50a. The unit ships as a complete radiator (radiator cap excluded) and includes protective foam in the packaging to prevent deformation during transport.

How does this radiator fit my Altima or Maxima?

The DWVO radiator is manufactured to replicate OEM form and function, meaning bolt locations, inlet/outlet positions, and overall dimensions align with factory specifications. It supports automatic and manual transmissions depending on the vehicle configuration.

• Compatible models: Nissan Altima 2007–2018 (2.5L L4) and Maxima 2009–2023 (3.5L V6).
• OEM reference numbers matched: 21410zn50a, 21460zn50a.
• Designed as a direct drop-in replacement—minimal modifications required.

What materials and construction ensure long-term durability?

This radiator combines an aluminum core with TIG-welded connections and PA66 GF30 inlet/outlet tanks to resist cracking and corrosion. A treated external coating and brass transmission oil cooler add further protection for mixed driving conditions and heat cycles.

• High-density multi-louvered fins for improved heat dissipation.
• TIG-welded joints and reinforced plastic tanks for leak resistance.
• Brass oil cooler integrated for models with transmission cooling lines.

What comes in the package and is installation difficult?

Package contents include one complete DWVO radiator and a user manual; a radiator cap is not included. The unit ships with corner foam inserts to prevent bending and damage—professional installation is recommended to ensure proper coolant routing and pressure testing.

• Included: DWVO complete radiator, user manual, protective foam padding.
• Not included: radiator cap, coolant, or mounting hardware beyond OEM-compatible fittings.
• Tip: Pressure-test and bleed the cooling system after installation for best results.

Will this radiator improve cooling performance?

The upgrade focuses on restoring factory cooling capacity and maintaining stable engine temperatures under load. The denser fin pattern and efficient core construction help the cooling system reject heat effectively without altering engine tuning.

• High-efficiency fins increase surface area for quicker heat transfer.
• Core design balances flow rate and pressure to match OEM specifications.
• Suitable for daily driving, towing within vehicle limits, and varied climates.

Who is this for: The DWVO radiator is aimed at Nissan owners seeking an OEM-compatible replacement for a failing or damaged cooling core on Altima (2007–2018) and Maxima (2009–2023) models. It’s a good choice for repair shops, DIY mechanics with experience in cooling system service, and drivers who want a long-lasting, drop-in radiator that restores factory fit and function without aftermarket modifications.
