17117618771 Water Tank Guard | Structural Side Protection for Cooling System Stability

Reinforced 17117618771 Water Tank Guard utilizes impact-modified polypropylene construction with integrated mounting reinforcements. The contoured design maintains 2.5mm clearance from radiator components while providing 360° debris deflection. Molded alignment pins ensure ±0.8mm positioning accuracy relative to factory mounting brackets.

Aerodynamic venturi channels replicate OEM airflow patterns, maintaining optimal cooling system efficiency. Pre-drilled fastener locations accommodate M8 bolts with 12Nm torque specifications. The textured surface finish matches original underbody appearance while enhancing stone chip resistance.
