The factory plastic coolant bleed screw on virtually every BMW and MINI cooling system is one of the most well-known weak points in the entire chassis — over time, the plastic becomes brittle from sustained heat exposure and breaks during routine cooling system service, often snapping off inside the radiator or expansion tank. When this happens, what should be a simple coolant bleed procedure becomes an expensive recovery job. This billet aluminium replacement permanently eliminates the failure mode with rigid metal construction that won't crack, snap, or strip during service. The 6mm Allen head design enables easy removal with a standard hex key — significantly faster and more reliable than the awkward cross-head factory design.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eSturdy and durable construction – aircraft-grade billet aluminium alloy permanently eliminates the brittleness and snapping failures of the factory plastic bleed screw\u003c\/li\u003e\n\u003cli\u003eDirect OE replacement design – manufactured to factory specifications matching original equipment part numbers 11537793373, 17111712788, and 17110141325\u003c\/li\u003e\n\u003cli\u003e6mm Allen head – easier and faster removal compared to the awkward cross-head factory design, using a standard hex key tool\u003c\/li\u003e\n\u003cli\u003eCNC machined precision – ensures perfect dimensional fitment to factory cooling system mounting points without modification\u003c\/li\u003e\n\u003cli\u003eAnodized surface finish – delivers corrosion and abrasion resistance with a clean, professional aesthetic that adds visual appeal to the engine bay\u003c\/li\u003e\n\u003cli\u003eWide chassis compatibility – fits virtually the entire BMW and MINI lineup from 1997 onwards\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCondition: 100% Brand New\u003c\/li\u003e\n\u003cli\u003eType: Cooling System Coolant Bleed Screw\u003c\/li\u003e\n\u003cli\u003eMaterial: Billet Aluminium Alloy\u003c\/li\u003e\n\u003cli\u003eConstruction: CNC Machined\u003c\/li\u003e\n\u003cli\u003eSurface Finish: Anodized\u003c\/li\u003e\n\u003cli\u003eHead Type: 6mm Allen \/ Hex\u003c\/li\u003e\n\u003cli\u003eItem Weight: 0.012 kg\u003c\/li\u003e\n\u003cli\u003eQuantity: 1 piece per pack\u003c\/li\u003e\n\u003cli\u003ePosition: Cooling System Bleed Port\u003c\/li\u003e\n\u003cli\u003ePurpose: Direct OE Replacement \/ Maintenance Upgrade\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eOE \/ Replacement Part Numbers:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e11537793373 \/ 11 53 7 793 373\u003c\/li\u003e\n\u003cli\u003e17111712788 \/ 17 11 1 712 788\u003c\/li\u003e\n\u003cli\u003e17110141325 \/ 17 11 0 141 325\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eFitment:\u003c\/h6\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible with virtually all BMW and MINI vehicles using factory bleed screw part numbers 11537793373 \/ 17111712788 \/ 17110141325.
