CSF 7085 High-Performance All-Aluminum Radiator for Toyota 4Runner

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your 4Runner running at its best, a CSF Heavy-Duty/High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on and off road, a heavy-duty performance radiator is a must-have for off-roaders, overlanders, and adventurers. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab. CSF manufactures the most advanced and efficient radiator in the industry for your 4Runner. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. The CSF #7085 Cooling product is designed to be a "Drop-In Fit" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.

Keep your Toyota 4Runner operating at its best with the CSF 7085 Heavy-Duty High-Performance All-Aluminum Radiator. Designed for demanding street, off-road, overland, and adventure applications, this radiator provides efficient heat dissipation and durable performance. CSF combines decades of radiator manufacturing experience with advanced tube, fin, and airflow technologies to help manage engine temperatures under demanding driving conditions. This replacement radiator is engineered as a true drop-in fit for the original equipment location, helping simplify installation without vehicle modifications unless otherwise noted by the manufacturer.
CSF's exclusive B-Tube Technology uses specially formed aluminum tubes with a brazed seam for increased strength and improved heat-transfer performance. The design increases the available heat-transfer surface while supporting efficient dual liquid laminar flow. Ultra-efficient, multi-louvered fins are precisely aligned to promote airflow through the core and maximize heat rejection. The radiator also includes an upgraded automatic transmission cooler integrated into the lower end tank, making it a practical cooling solution for Toyota 4Runner applications equipped with an automatic transmission. Its all-aluminum construction is TIG welded for strength, durability, and long-term reliability.
Each CSF 7085 radiator is individually leak and pressure tested to support dependable service. CNC-machined mounting brackets help provide accurate fitment and secure installation, while the polished finish delivers a clean appearance under the hood. This radiator is designed for select Toyota 4Runner applications from the listed model years, including 2010, 2011, 2013, and 2015; verify vehicle configuration and application details before ordering. Professional installation is recommended if you are not comfortable performing cooling-system repairs. The product includes a 2-year limited warranty and is built to provide reliable cooling performance for daily driving, towing, trail use, and extended off-road travel.
