Material Engineering
High-density polymer composite maintains dimensional stability under thermal stress. Glass-fiber reinforcement provides structural rigidity without weight penalty. Chemical-resistant formulation withstands coolant exposure and underhood contaminants. Temperature-tolerant construction performs consistently between -40°F to 230°F. Optimized wall thickness balances strength and vibration absorption. UV-stabilized surface prevents material degradation from engine heat. Precisely molded mounting bosses ensure secure component retention. Impact-modified material withstands incidental contact during maintenance. Color-stable compound maintains OEM appearance throughout service life. Flexible design accommodates thermal expansion without stress fractures. Smooth surface finish prevents fluid retention and debris accumulation.
Design Integration
Factory-specified mounting points align with BMW's modular cooling system. Integrated cable routing channels protect electrical connectors. Service-friendly design allows coolant tank removal without frame disassembly. Precision-engineered clearances maintain airflow around critical components. Vibration-isolating features protect sensor connections. Thermal expansion gaps prevent material stress during temperature fluctuations. Access ports enable coolant level inspections. Alignment guides simplify installation procedures. Contoured edges prevent interference with moving engine components. Modular design accommodates factory-installed auxiliary systems. Drainage channels prevent fluid accumulation in critical areas. Maintenance-friendly configuration supports rapid coolant system servicing.
Compatibility Information
Designed for 2017-2020 BMW X5 G05 models equipped with factory-standard cooling systems. Verified compatibility includes all gasoline and diesel variants within specified production years. Direct replacement for original equipment mounting frames in vehicles with N55, B58, or M57D engines. Maintains proper alignment with BMW's intelligent coolant level monitoring systems. Compatible with models featuring auxiliary radiators or transmission coolers. Material composition ensures compatibility with OEM coolant types and underhood cleaning processes. Not suitable for vehicles with modified cooling system layouts or aftermarket components that alter factory mounting points. Requires vehicles with standard coolant reservoir configurations. Ensures proper functionality of temperature management systems.
