Over time, factory rubber hardens, stretches, and develops micro-fissures along the radiator necks and water pump housing. Under operating pressures, degraded stock hoses risk softening and ballooning or splitting along stress points, leading to sudden coolant evacuation and catastrophic cylinder head warping.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis cooling upgrade features heavy-duty 3-ply polyester-reinforced silicone with a consistent 4.5 mm wall thickness designed to maintain structural rigidity under peak engine bay temperatures and fluctuating pressure spikes. Silicone withstands operating temperatures up to 350°F without dry-rotting or hardening. Pre-formed to exact factory routing for the 289 and 302 small blocks, the kit provides full coolant flow through upper, lower, and critical water-pump bypass passages, secured by heavy-gauge stainless steel worm-drive clamps.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Upper Silicone Radiator Hose (Black, 3-ply, 4.5 mm wall)\u003c\/li\u003e\n  \u003cli\u003e1x Lower Silicone Radiator Hose (Black, 3-ply, 4.5 mm wall)\u003c\/li\u003e\n  \u003cli\u003e1x Thermostat Bypass Silicone Hose (Black, 3-ply, 4.5 mm wall)\u003c\/li\u003e\n  \u003cli\u003e6x Stainless Steel 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;\"\u003e1964-1968 Ford Mustang\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;\"\u003eWindsor V8 (4.7L 289 \/ 5.0L 302) \/ Gen 1\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;\"\u003e200-271 hp \/ 282-312 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;\"\u003eult70490\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\u003e1964-1968 Ford Mustang 4.7L (289 ci) Windsor V8\u003c\/li\u003e\n  \u003cli\u003e1968 Ford Mustang 5.0L (302 ci) Windsor V8\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 Gen 1 Mustang?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1964-1968 Ford Mustang equipped with the \u003cstrong\u003eWindsor V8\u003c\/strong\u003e (289 ci and 302 ci).
