The \u003cstrong\u003eKA24DE\u003c\/strong\u003e and early \u003cstrong\u003eKA24E\u003c\/strong\u003e engine bays run notoriously tight clearances near the exhaust manifold, accelerating dry-rot, hardening, and internal delamination of the OEM rubber. Under hard driving, elevated cooling system pressure forces compromised rubber hoses to expand, balloon, and eventually split along the molded seams, resulting in sudden coolant loss, severe cylinder head warping, and catastrophic head gasket failure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis radiator hose kit utilizes high-grade, 3-ply polyester-reinforced silicone with a nominal 4.5 mm wall thickness to resist extreme temperature spikes and expansion up to high burst ratings. Molded to exact OEM routing specifically for the stock radiator and engine layout, the multi-layer silicone resists oil contamination, ozone degradation, and electrochemical degradation far beyond standard synthetic rubber. The smooth internal bore optimizes coolant velocity while minimizing flow turbulence across the upper and lower radiator necks. Included stainless steel worm-drive clamps apply uniform radial tension without cutting into the silicone jacket, maintaining a leak-free seal across wide ambient-to-operational thermal swings.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 Silicone Radiator Hoses (black, 3-ply, 4.5 mm wall)\u003c\/li\u003e\n  \u003cli\u003e4 Stainless Worm-Drive Clamps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1989-1994 Nissan 240SX\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eKA24DE (2.4L) \/ S13\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e155 hp \/ 160 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1989-1994 Nissan 240SX 2.4L KA24DE (S13)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the S13 240SX?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1989-1994 Nissan 240SX equipped with the \u003cstrong\u003eKA24DE\u003c\/strong\u003e engine. \u003cstrong\u003eThis kit does not fit models equipped with the SR20DET engine.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installing these hoses?\u003c\/h4\u003e\n\u003cp\u003eYes, you must fully bleed all trapped air from the cooling circuit using the factory bleed bolt on the engine to prevent air pockets and localized overheating.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Enthusiast Standard\u003c\/h3\u003e\n\u003cp\u003eKeep your rear-wheel-drive icon running at peak track capability with cooling plumbing engineered to withstand the sustained high-RPM heat and stress of drift and circuit duty.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68059625685240,"sku":"DS-EMQGBD96J","price":56.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/silicone-radiator-hose-kit-for-nissan-240sx-1989-1994-2-4l-1.jpg?v=1794371018","url":"https:\/\/performancechiptuning.com\/de\/products\/silicone-radiator-hose-kit-for-nissan-240sx-1989-1994-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
