Frequently Asked Questions
The factory plastic coolant reservoir hose flange on BMW E8X and E9X models with the N52 engine is highly prone to cracking and breakage — both during routine maintenance and in everyday use. Once the flange fails, coolant leaks and dangerously elevated engine temperatures follow rapidly. This high-performance replacement kit permanently resolves that weakness by pairing a 6061 anodized aluminum alloy flange with a triple-layer reinforced silicone hose rated to 3 bar pressure and high-temperature operation. An anti-aging silicone formula maintains long-term flexibility without hardening or cracking, upgraded stainless steel hose clamps replace the factory units unsuitable for reuse, and the finished result is a significantly more reliable and visually superior cooling system connection than the OEM plastic setup.
Features:
- 6061 anodized aluminum alloy flange permanently replaces the factory plastic flange – eliminating the cracking and breakage failure mode on E8X and E9X cooling systems
- Triple-layer reinforced silicone hose rated to 3 bar pressure and high operating temperatures for long-term cooling system integrity
- Special anti-aging silicone formula maintains flexibility over time – no hardening, no cracking, and no risk of sealing failure
- Upgraded stainless steel hose clamps included – factory clamps are not suitable for reuse after extended service
- Direct replacement for OEM part numbers 17127618510 and 17127565093
