Plastic end tanks crack and leak, internal passages corrode and restrict flow, and the overall cooling capacity of a worn factory radiator is a fraction of what it was when new. Even a factory-condition S13 radiator has limited cooling capacity for performance driving — the KA24DE runs warm under sustained load, and track use or aggressive street driving can push coolant temperatures into concerning territory. The Mishimoto aluminum radiator addresses both problems simultaneously: it replaces aging, failure-prone factory hardware with a durable, all-aluminum unit that provides 30% more cooling capacity than the factory specification.\u003c\/p\u003e\n\u003ch4\u003eThe S13 240SX Platform:\u003c\/h4\u003e\n\u003cp\u003eThe 1989–1994 Nissan 240SX (S13) is one of the most beloved and versatile Japanese sports car platforms in the enthusiast community — a lightweight, rear-wheel-drive chassis with a well-balanced suspension layout that has made it a staple of drifting, time attack, and grassroots motorsport for decades. Whether running the factory KA24DE or a popular engine swap, the S13’s cooling system is a critical reliability component that deserves the same attention as the rest of the build. The Mishimoto aluminum radiator is one of the most straightforward and impactful cooling system upgrades available for the platform.\u003c\/p\u003e\n\u003ch4\u003eWhy Mishimoto?\u003c\/h4\u003e\n\u003cp\u003eMishimoto is one of the most recognized names in performance cooling components, with a comprehensive lineup of aluminum radiators, intercoolers, oil coolers, and cooling accessories for import and domestic performance vehicles. Their 240SX radiator is engineered specifically for the S13 platform — not a universal fit — ensuring correct fitment, proper hose connection placement, and compatibility with the factory cooling system layout.\u003c\/p\u003e\n\u003ch4\u003ePerfect For:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1989–1994 Nissan 240SX (S13) KA24DE owners replacing a worn, leaking, or inadequate factory radiator\u003c\/li\u003e\n\u003cli\u003eS13 track day and drift builds requiring improved cooling capacity for sustained high-performance use\u003c\/li\u003e\n\u003cli\u003eStreet builds in hot climates where the factory radiator struggles to maintain safe coolant temperatures\u003c\/li\u003e\n\u003cli\u003eEngine rebuilds and restoration projects where the cooling system is being refreshed alongside the engine\u003c\/li\u003e\n\u003cli\u003eAnyone building a reliable, performance-focused S13 who wants a long-term cooling system upgrade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePro Tip:\u003c\/strong\u003e Pair with the Mishimoto 240SX aluminum fan shroud for maximum cooling efficiency — a properly sealed fan shroud ensures the radiator fan draws air through the entire core rather than just the area directly in front of the fan blade, significantly improving low-speed and stationary cooling performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e KA24DE fitment only.
