 7701470460 7701466975 Engine Radiator Coolant Expansion Water Bottle Tank For RENAULT NISSAN

Engineered for Renault and Nissan vehicles, these coolant reservoirs feature high-density polyethylene construction with UV-resistant additives to prevent cracking and discoloration under prolonged engine heat exposure. The seamless blow-molded design ensures leak-proof performance while maintaining structural integrity under pressure fluctuations, with precisely calibrated venting systems that regulate cooling system pressure within OEM specifications. Molded mounting brackets enable direct bolt-on replacement without modification, and translucent sidewalls with integrated level indicators allow for instant coolant condition monitoring. The reservoirs' optimized internal baffling prevents coolant surge during aggressive maneuvers while maintaining consistent flow to the radiator, with chemical-resistant formulations that withstand modern extended-life coolants. Designed for exact fitment across Renault and Nissan platforms, these units feature reinforced neck joints to prevent stress cracks around the pressure cap and precisely positioned hose connections that eliminate kinking for unrestricted coolant circulation throughout the engine's operating temperature range.
