CSF 7085 Radiator for TOYOTA 4Runner 2010-2019

Part number7085

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to ensuring your 4Runner's engine cooling and maximum performance. The all-aluminum CSF Heavy-Duty/High-Performance Radiator is designed for both on-road and off-road use, making it an essential upgrade for SUVs, overland vehicles, and adventure seekers. This radiator features a 2-row core with CSF's exclusive B-Tube Technology. Unlike conventional "O" style oval radiator tubes, CSF utilizes specially engineered "B" shaped tubes. These B-tubes are meticulously formed and then seam-soldered for a leak-proof seal. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than traditional "O" style welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes' heat exchange by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes versus one larger tube within the same space criteria. With B-tubes, "dual laminar flow" can be achieved. CSF also employs highly efficient louvered fins that are carefully and precisely aligned to maximize airflow through the radiator core. Fin characteristics are meticulously measured and calculated for each application, and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

The CSF 4Runner Radiator is a true "Drop-in fit" design, requiring no modifications for installation. OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet connections are designed to match OEM specifications, allowing you to use either OEM or aftermarket hoses. Whether you're off-roading, towing, or simply driving your vehicle, trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
