CSF High Performance All-Aluminum Radiator

Product Description

Enthusiasts continue to push the limits of their 4Runners – from driving in the desert sand dunes, navigating up mountain trails, to towing and hauling gear for overlanding and even partaking in extreme rock crawling and hill climbing. One common issue found in such off-road activities is heat soak. Most off-road trails, especially rock crawling and hill climbing, are usually traversed at very low speeds with high engine power output. This can lead to engine and transmission overheating and leave drivers stranded, even in the desert or on a trail in the middle of nowhere with no rescue nearby.  CSF’s new 5^th gen 4Runner high-performance radiator fixes potential heat soak and overheating issues by increasing the capacity of the radiator and increasing the efficiency of the radiator core. Utilizing CSF’s exclusive B-Tube Technology and increasing the core size from a tiny 1-row 22mm core to an ultra-efficient 2 row 42mm core, CSF has taken care of any worries of overheating. With the increased size of the radiator, CSF has also increased the capacity of the transmission oil cooler found in the bottom tank – this will help keep transmission temperatures in check, especially when towing. CSF has answered the call for increased performance and durability with its new 5^th gen Toyota 4Runner All Aluminum Heavy-Duty Radiator. It’s the perfect answer to upgrading and safe-guarding against the weak OEM radiator with plastic end tanks.  After several years, the plastic tanks can start to become brittle from excessive heat cycles, can crack under heavy vibration, or can burst from extreme pressures and temperatures (including cold starts in freezing temperatures). CSF’s 100% TIG welded all-aluminum end tanks prevent potential leakage when compared to the weaker plastic tanks that utilize a rubber gasket and a crimp design to seal. For additional strength and reliability, all of CSF’s all-aluminum radiators have CNC machined mounting brackets and pins – a vast improvement over the OEM plastic mounting points, which can crack under high vibration or stress – common occurrences when off-roading or towing.
