Cold weather exposes weak plastic connections to repeated thermal expansion, causing cracks that reduce cabin warmth and pressure loss. This assembly replaces those vulnerable points with corrosion-resistant aluminum fittings and a durable U-shaped rubber tube, restoring steady circulation through the engine heater core without requiring custom fabrication or specialty tools. Simple bolt-in geometry matches most common automotive layouts, keeping maintenance straightforward and preventing unexpected roadside breakdowns during winter operations.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Practical Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRemove failing plastic junctions to stop gradual coolant loss and keep passenger heating consistent.\u003c\/li\u003e\n\u003cli\u003eApply thread-safe torque when tightening aluminum couplings; overtightening can strip machined internal threads.\u003c\/li\u003e\n\u003cli\u003eMatch the fitting pair size to your existing hose diameter before routing the bypass line across the firewall.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCore Material: Aluminum alloy billets paired with reinforced rubber tubing\u003c\/li\u003e\n\u003cli\u003eHose Shape: U-design optimized for standard heater core clearance paths\u003c\/li\u003e\n\u003cli\u003eFitting Configurations: 5\/8\" to 5\/8\", 5\/8\" to 3\/4\", and 3\/4\" to 3\/4\"\u003c\/li\u003e\n\u003cli\u003eCompatibility: Integrates with most common automotive heater hose assemblies\u003c\/li\u003e\n\u003cli\u003eMounting Hardware: Pre-sized stainless steel worm clamps included for secure band sealing\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x U-shaped rubber bypass hose\u003c\/li\u003e\n\u003cli\u003eVariable hose fitting ends covering 5\/8\"–5\/8\", 5\/8\"–3\/4\", and 3\/4\"–3\/4\" options\u003c\/li\u003e\n\u003cli\u003e4 x metal hose clamps for leak-free joint compression\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDepressurize and drain the cooling loop completely before removing original hardware.\u003c\/li\u003e\n\u003cli\u003eFlush the interior of the rubber hose before assembly to prevent debris restriction.\u003c\/li\u003e\n\u003cli\u003eTest for drips after initial startup; minor settling may require a final half-turn clamp adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e\n\u003cp\u003ePrecision-engineered components delivered safely since 2002 via intercyprus.com — trusted by builders who demand consistent part reliability.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"full kits","offer_id":55111909540182,"sku":"1005010382149753-full kits","price":42.33,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S40e9a22ccfad4d9095d9357341bbb5f15.webp?v=1787816041","url":"https:\/\/www.intercyprus.com\/products\/626-001-billets-aluminum-engine-heater-core-bypass-kit-with-5-8-3-4-hose-diameter-compatible-with-most-common-heater-hoses-1","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
