BMW E81 / E82 / E87 / E88 1 Series, E90 / E91 / E92 / E93 3 Series & E84 X1 Lower Radiator to Thermostat Silicone Hose Repair Kit with Billet Aluminum Flange (N52N / N53 Engines / Replaces 17127564478)

Permanently solve the broken plastic radiator flange failure on your BMW N52N or N53 engine with this premium lower radiator hose repair kit, featuring a 6061 billet aluminum flange and triple-ply reinforced silicone hose for permanent durability and reliable cooling system sealing. The factory plastic radiator-to-thermostat flange is one of the most well-known weak points on N52N / N53-equipped BMW chassis — over time, the plastic flange becomes brittle from heat cycling and cracks or breaks entirely, causing coolant loss, overheating, and engine damage if not addressed promptly. This repair kit replaces the failure-prone plastic flange with rigid billet aluminum construction and upgrades the factory rubber hose to high-pressure (3-bar rated) triple-layer silicone with an anti-aging formula that maintains long-term flexibility without hardening, cracking, or developing the seal failures that affect aged factory hoses. Premium stainless steel hose clamps replace the inferior factory clamps for permanent leak-free sealing.

Features:

• 6061 billet aluminum flange – permanently eliminates the cracking and breakage failure mode of the factory plastic radiator flange

• Triple-ply reinforced silicone hose – high-pressure (3-bar rated) construction with anti-aging formula maintains long-term flexibility without hardening or cracking

• Upgraded stainless steel hose clamps – significantly more durable and reliable than the factory clamps which are not suitable for reuse after removal

• Direct OE replacement design – manufactured to factory specifications matching original equipment part number 17127564478 for clean, modification-free installation

• Anodized flange surface finish – delivers superior corrosion resistance and a clean professional aesthetic for long-term engine bay use

• High-temperature resistance – silicone construction maintains structural integrity under sustained engine operating temperatures where factory rubber hoses begin to degrade

• Aesthetic engine bay enhancement – customized silicone hose appearance elevates the engine bay beyond the cheap feel of factory rubber and plastic components

• Condition: 100% Brand New
