Koyo Performance Radiator – Nissan Skyline R33 RB25DET / RB26DETT MT 1993–1999 Application: Nissan Skyline | E-HCR33 (GTS25-T) & E-BCNR33 (GT-R) | RB25DET & RB26DETT Turbo Petrol RWD | Manual Transmission Part Number: HH020442 / KH020442 ⚠️ Note: This radiator does NOT fit the Nissan Skyline R34 GT-R (BNR34). Please ensure you select the correct part for your chassis. The R33 Skyline is a genuine icon — whether it's the GTS25-T with its RB25DET or the legendary GT-R with the RB26DETT twin-turbo inline-six. Both engines generate serious heat under hard driving, and the factory cooling system has its limits when you're pushing boost on track or in spirited street use. Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the R33, engineered to the same factory fit and mounting points as the OE unit. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required. Why Koyorad? Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core. Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements. Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal. OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install. Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
