Denso 221-9315 Radiator

Denso Radiator 221-9315 for Nissan NV Vans

The Denso 221-9315 radiator is built for Nissan NV1500, NV2500, and NV3500 applications with OE-style fitment and cooling performance. It uses a 35.1600-inch core height, 24.8400-inch core width, and 1.5700-inch core thickness to match the factory cooling package.

Denso’s radiator line is based on OE supplier experience, with configurations, tanks, fin pitch, core dimensions, and materials engineered to meet original manufacturer standards. This radiator includes a transmission oil cooler and uses 1.3800-inch inlet and outlet diameters for direct replacement service.

This part cross-references Spectra Premium CU13335 and CSF 3550 for the same application.

What This Radiator Helps Address

• Engine overheating caused by a failing radiator core
• Coolant loss from cracks, leaks, or corrosion
• Transmission temperature concerns when the cooler circuit is compromised
• Poor heat transfer from restricted or damaged cooling passages
• Fitment issues from using a radiator with incorrect core size or hose connections

Installation Notes and Tips

Verify the inlet and outlet diameters, core dimensions, and transmission cooler routing before installation. Inspect hoses, clamps, and coolant condition during replacement, and confirm the radiator mounts and fan shroud alignment on the Nissan NV1500, NV2500, or NV3500. Proper system bleeding and coolant refill procedures help restore stable operating temperature after installation.

Quality Assurance

Denso supplies radiators to OE vehicle manufacturers worldwide, and this radiator is built to the same standards used in original equipment development. Each unit is subjected to durability and function testing to support reliable cooling performance and fitment.
