CSF Radiators 7213 - High-Performance All-Aluminum Radiator

Introducing the CSF Radiators 7213, a high-performance all-aluminum radiator designed specifically for the 6th Generation Subaru Outback and Legacy models from 2015 to 2019. If you’re an off-roading enthusiast or someone who enjoys overlanding, you know how demanding these activities can be on your vehicle’s engine. The 2.5L (FB25) naturally aspirated motor is robust, but it can struggle under the strain of tough terrains and added weight. That’s where the CSF 7213 comes in.

This radiator features a 42mm 2-row aluminum core that not only boosts fluid capacity but also enhances heat dissipation. Customers have noted a significant drop in engine temperatures even during long drives in challenging conditions. One user mentioned, “I took my Outback on a week-long camping trip, and I never once saw the temperature gauge rise above normal, even with all my gear.”

With CSF's exclusive B-Tube technology, heat transfer is improved by around 15% compared to standard radiators. The multi-louvered fins maximize airflow, which is essential for maintaining optimal temperatures, especially when your vehicle is moving at lower speeds off-road. One satisfied customer remarked, “The airflow is noticeably better, and I can feel the difference when I’m climbing hills.”

The construction is solid, with high-grade aluminum end tanks that are TIG welded to the core, providing greater strength compared to the OEM's plastic end tanks. This design reduces the risk of failure, a concern many users have with factory radiators. As one reviewer pointed out, “I used to worry about my radiator failing during tough trails, but with this upgrade, I feel much more secure.”

Installation is straightforward, as the CSF 7213 is designed for a true plug-and-play fit. There’s no need for modifications, trimming, or cutting, which has been a relief for many DIY enthusiasts. A customer shared, “I had it installed in under an hour, and it fit perfectly without any hassle.”
