17117933879 Cover | Cooling System Protection

Engineered specifically for 2018-2019 BMW 5 Series G38 models, the 17117933879 Cover serves as a protective upper guard for coolant reservoirs using impact-modified polypropylene construction. Its aerodynamic contouring minimizes wind resistance while deflecting road debris from critical cooling components. Precision-molded attachment points ensure tool-free installation with positive engagement clips that maintain secure positioning through extreme vibration cycles. The ribbed underside structure provides torsional rigidity without compromising impact absorption characteristics during minor collisions.

UV-stabilized polymer formulation maintains color integrity and structural properties through prolonged sun exposure. Strategic airflow channels prevent heat buildup around coolant hoses while allowing efficient heat dissipation from the radiator assembly. Integrated drainage pathways prevent water accumulation that could lead to corrosion. The textured surface finish matches factory components while providing improved grip during maintenance procedures. Environmental testing confirms operational integrity across -30°C to 120°C temperature ranges with resistance to automotive fluids including coolant, brake fluid, and road salts. The cover's modular design allows removal without disturbing adjacent components, significantly reducing service time during cooling system maintenance.
