The NWT UZ Swap Radiator is compatible with 1UZ-FE, 2UZ-FE, and 3UZ-FE engines. Fitment is based on the recipient chassis, not the engine variant. All three UZ engines use the same radiator in standard 1989–1995 Pickup and 4Runner applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What chassis modifications are required to install this radiator?\u003c\/strong\u003e\u003cbr\u003eA: This radiator requires permanent fabrication work. It is not a bolt-in replacement. You must cut the lower radiator support across the bottom and the side brackets to achieve the necessary core clearance. A minimum 1\" body lift is also required for proper hood clearance and radiator positioning. These are irreversible modifications that should only be undertaken by builders prepared to commit to the swap.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My vehicle is not a 1989–1995 Pickup or 4Runner — can I still order this radiator?\u003c\/strong\u003e\u003cbr\u003eA: Possibly, but you must contact sales@northwesttoysllc.com before ordering. Non-standard chassis applications require precise measurements of your core support opening to ensure proper fitment. We build to order, so custom sizing may be possible — but we need your measurements first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How long does it take to receive this radiator after ordering?\u003c\/strong\u003e\u003cbr\u003eA: This radiator is built to order and ships in approximately 4–6 weeks. Do not order this part on a tight timeline — plan your build schedule accordingly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this radiator with a non-NWT motor mount or header setup?\u003c\/strong\u003e\u003cbr\u003eA: This radiator is engineered around North West Toys motor mount and header configurations. If you are running a different swap kit, confirm with NWT before ordering.  Engine positioning differences can affect hose routing, fan clearance, and overall fit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What's the difference between ordering the radiator alone versus the full cooling system package?\u003c\/strong\u003e\u003cbr\u003eA: The standalone radiator is the core of the system. The NWT 1UZ Cooling System Package adds the shroud, 16\" electric fan, thermostatic fan controller with harness, and upper and lower radiator hoses — everything you need for a complete, integrated cooling solution. For most builders doing a full swap, the package eliminates the need to source multiple components and ensures everything is matched and tested to work together.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRelated Toyota Parts You May Need\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"padding-left: 1.5em; margin: 0;\"\u003e\n\u003cli style=\"text-indent: -1.5em; padding-left: 1.5em;\"\u003e\n\u003cstrong\u003eNWT 1UZ Cooling System Package\u003c\/strong\u003e — Includes this radiator plus the NWT shroud, 16\" electric fan, thermostatic controller \u0026amp; harness, and upper\/lower hoses.

The stock cooling infrastructure on these chassis was engineered for inline-four and V6 engines, producing a fraction of the combustion heat a UZ engine generates. Using an undersized or generic radiator in a UZ swap isn't just a performance compromise — it's a reliability risk. Heat soak on the trail, slow-speed crawling in the desert, and long highway pulls all stress a cooling system that isn't matched to the engine.\u003c\/p\u003e\n\u003cp\u003eThe NWT UZ Swap Radiator was built specifically because the right solution didn't exist off the shelf. The dual-row 1\" tube core, TIG-welded aluminum construction, and nutsert mounting system are all deliberate engineering decisions made for this specific application. The 5-year warranty reflects the level of confidence that comes from a part designed, built, and tested in-house — not sourced from an overseas catalog.\u003c\/p\u003e\n\u003cp\u003eThis radiator requires chassis fabrication. If you're ready to make that commitment, you're getting a cooling solution purpose-built for your swap.
