Frequently Asked Questions
There is a well-documented design defect in the factory upper radiator hose on N52-engined E8X and E9X models — the plastic flange where the hose connects to the expansion tank outlet is prone to cracking and breakage during routine maintenance or daily use, resulting in coolant leakage and dangerously elevated engine temperatures. This high-performance repair kit permanently resolves that weakness by replacing the factory plastic flange with a 6061 aluminum alloy unit and substituting the OEM hose 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, and upgraded stainless steel hose clamps replace the factory units that are unsuitable for reuse after extended service.
Features:
- 6061 anodized aluminum alloy flange replaces the factory plastic flange – permanently eliminates the risk of breakage and coolant leakage at the expansion tank connection point
- Triple-layer reinforced silicone hose rated to 3 bar pressure and high operating temperatures – purpose-built for long-term cooling system reliability
- Special anti-aging silicone formula maintains flexibility over time – no hardening, no cracking, and no sealing failure risk
- Upgraded stainless steel hose clamps included – factory clamps are not suitable for reuse after extended service and are replaced as part of this kit
- Direct replacement for OEM part number 17127531579 – N52 engine applications only
