Replacing the original radiator with this one relieved my worries of the transmission cooler leaking and causing the transmission fluid to mix with radiator antifreeze. (A common problem with Frontier trucks.) Review: Perfect fit for 2007 Nissan Xterra - After a few weeks and few hundred miles the Denso radiator performs well. It is installed in a 2007 Nissan Xterra. The original radiator made by Calsonic started leaking coolant after 45k miles. Although the original "Radiator assembly" is under extended warranty from Nissan, the Nissan dealer refused to honor the warranty. According to the terms "internal leaking" must occur first then they will (probably) do it. Internal leaking means your coolant will mix with transmission fluid and your transmission will go bust! How smart! Dealers offered to replace the radiator for $1000. I did it at home for $100 in a few hours. The Denso radiator is a perfect fit, and is perfectly identical with the OEM Calsonic which is sort of scary. ## Features - Efficient Fuel Consumption - Package Dimensions: 78.74 L x 12.7 H x 77.47 W (centimeters) - Fit type: Vehicle Specific - Package Weight: 18.65 pounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004J317JC | | Best Sellers Rank | #1,711,569 in Automotive ( See Top 100 in Automotive ) #9,804 in Automotive Replacement Engine Radiators | | Brand Name | Denso | | Closure Type | Twist-On | | Color | Silver | | Compatible with Vehicle Type | Car, Truck | | Customer Reviews | 4.6 4.6 out of 5 stars (255) | | Exterior Finish | Machined | | Global Trade Identification Number | 00042511178786 | | Included Components | Radiator | | Item Type Name | Radiator | | Item Weight | 1 Pounds | | Manufacturer | Denso | | Manufacturer Part Number | 221-3409 | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Material Type | Aluminum | | Model Number | 221-3409 | | Style Name | Modern | | UPC | 042511178786 | ## Product Details - **Brand:** Denso - **Color:** Silver - **Exterior Finish:** Machined - **Material:** Aluminum - **Vehicle Service Type:** Car, Truck ## Images ![Denso 221-3409 Radiator - Image 1](https://m.media-amazon.com/images/I/91XnFA692HL.jpg) ## Questions & Answers **Q: Will this fit my 2008 nissan frontier 4.0 with 6speed manual?** A: The one I bought was 5 auto. I'm pretty sure the man and auto rads are different. The auto has a trans cooler loop. **Q: does this have the attachment holes for the stock air transmission oil cooler that sits in front of radiator?** A: No. The oil-to-air transmission cooler mounts to the chassis in front of the radiator. **Q: Will this fit a 2006 pathfinder se?** A: Fit my 2009 Frontier with the 4.0 v6. Of you have the v8 pathfinder it might not work. **Q: Does this fit 2006 Nissan Xterra? and is it difficult to replace yourself?** A: Not sure on the Xterra, but this will fit the Frontier of the same year. The replacement is not easy, There is a lot of stuff in the way and even if you have some mechanical experience this is a day long job. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Avoid transmission failure *by J***T on March 11, 2025* Perfect fit and function.
