New Energy Power parts Expansion tank assembly 1311010-KT1D0

Crafted from food-grade, high-temperature resistant polyethylene (PE-HD) material, the expansion tank assembly exhibits excellent mechanical strength and impact resistance—withstanding temperatures from -40°C to 130°C without deformation. The inner surface of the tank is treated with a special anti-corrosion coating that resists chemical reactions with ethylene glycol-based coolants (commonly used in new energy vehicles), preventing rust, scale buildup, and material degradation. After 1,000-hour immersion testing in coolant, the tank shows no signs of cracking, leaking, or material discoloration, ensuring a service life of over 8 years under normal operating conditions. The tank’s lid is made of reinforced polypropylene (PP) with a nitrile rubber seal, providing a tight, leak-proof fit to maintain system pressure

This expansion tank assembly is specifically designed to fit new energy vehicle models, including pure electric and plug-in hybrid vehicles. It matches the original equipment (OE) dimensions of the 1311010-KT1D0 part number, with a mounting bracket spacing of 120mm and inlet/outlet port diameters of 25mm and 20mm respectively—ensuring seamless integration with existing cooling system pipelines. The assembly comes with pre-drilled mounting holes and all necessary hardware (nuts, bolts, and washers), allowing for direct replacement without modifications to the vehicle’s chassis or cooling system. It is compatible with major new energy vehicle brands and their specific cooling system configurations, reducing installation time by up to 30% compared to non-OE alternatives

The 1311010-KT1D0 expansion tank assembly incorporates multiple safety features to protect new energy power systems. Its pressure relief valve has a dual-stage design: the first stage releases excess pressure at 1.5 bar to prevent system overpressure, while the second stage acts as a backup at 1.8 bar to avoid catastrophic failure. The tank’s thickened sidewalls (5mm thickness) and rounded corner structure enhance impact resistance, reducing the risk of damage in case of minor collisions. A leak-proof check valve is installed at the outlet port, preventing coolant backflow and ensuring unidirectional fluid flow to the cooling circuit. Additionally, the tank’s transparent upper section allows for easy visual inspection of coolant level and quality, enabling early detection of contamination or fluid loss

The expansion tank assembly fully complies with international environmental and quality standards for new energy vehicle parts. It is RoHS-compliant, free of hazardous substances such as lead, cadmium, and hexavalent chromium, making it suitable for global markets including the EU, North America, and Asia. The assembly meets ISO 14001 environmental management standards and undergoes rigorous quality testing, including pressure cycle testing (10,000 cycles of pressure variation between 0.5-1.5 bar), vibration testing (10-2000 Hz, 10g acceleration), and temperature cycle testing (-40°C to 130°C, 500 cycles). Each unit is inspected for dimensional accuracy using 3D scanning technology, ensuring consistent fit and performance. The manufacturing process is certified under IATF 16949, with full traceability from raw material sourcing to final assembly, providing new energy vehicle manufacturers with reliable, high-quality components
