While the legendary 3.4L platform is known for its reliability, aging supporting systems like the cooling system can benefit from an upgrade, especially once you add larger tires, armor, and push the vehicle harder than stock. That is exactly why CSF developed this Heavy Duty All Aluminum Radiator specifically for 1996–2002 4Runners. Designed to increase cooling capacity, improve durability, and handle the added stress of modified builds, this radiator is a true performance upgrade over the factory unit.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eImportant note\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eDirect fit: True plug and play, drop in replacement with no trimming or cutting required.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTransmission cooler: Built in heavy duty 5 plate transmission cooler connects to OEM lines.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eFan shroud seal: Includes pre cut double sided adhesive foam strips to improve airflow efficiency.\u003c\/span\u003e \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eKey features\u003c\/span\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e2 row 42mm aluminum core: Increases coolant capacity and significantly improves heat dissipation.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eB Tube technology: CSF exclusive design increases heat transfer by approximately 15 percent over standard oval welded tubes.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMulti louvered fins: Maximizes airflow through the core for improved cooling performance.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAll aluminum construction: High grade aluminum end tanks TIG welded to the core for superior strength and durability.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eStronger than OEM: Eliminates the factory crimped plastic end tank weak point that is prone to failure over time.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eUpgraded transmission cooler: Heavy duty 5 plate internal cooler helps manage additional heat from towing, low range crawling, and oversized tires.\u003c\/span\u003e \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eWhy it matters for lifted and oversized tire builds\u003c\/span\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCorrects heat buildup: Larger tires effectively reduce your gear ratio, forcing the engine and transmission to work harder.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHandles added stress: Designed to manage the extra heat generated from crawling, towing, and modified setups.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eImproved long term reliability: Reinforced aluminum construction provides added confidence on and off the trail.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eIf you are building out a 3rd Gen 4Runner for serious trail use or simply want to future proof your cooling system, this CSF heavy duty radiator is a smart upgrade that keeps your rig running cool when it matters most.\u003c\/span\u003e\u003c\/p\u003e","brand":"CSF RACE","offers":[{"title":"Default Title","offer_id":46832606281897,"sku":null,"price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/1151\/3001\/files\/IMG-3536.webp?v=1771859276","url":"https:\/\/yota-wolf.com\/products\/csf-3rd-gen-toyota-4runner-heavy-duty-all-aluminum-radiator","provider":"YotaWolf","version":"1.0","type":"link"}
