51747460300 Tank Frame | Cooling System Compliance

Precision-engineered for BMW 5 Series G30 and G38 platforms, the 51747460300 Tank Frame utilizes glass-reinforced polyamide with thermal-stabilized formulation to maintain structural integrity across extreme temperature cycles. The injection-molded construction features integrated mounting points that align with factory positioning specifications, ensuring direct replacement compatibility without modification requirements.

Pressure-resistant design incorporates reinforced ribs along critical stress points, preventing deformation under cooling system pressures up to 2.2 bar. The geometric configuration maintains precise coolant level monitoring accuracy while accommodating factory sensor arrays without interference. Surface treatment combines chemical resistance with UV protection, preventing material degradation from engine bay exposure over extended service periods.

Sealing surfaces employ laser-leveled contact planes that maintain compression integrity with OEM gasket components. The integrated reservoir interface prevents coolant leakage through precision-tolerance mating surfaces. Installation alignment features include molded orientation guides that prevent incorrect positioning during maintenance procedures. Thermal expansion compensation gaps maintain dimensional stability across operating temperatures from -30°C to 130°C.
