Original coolant expansion tank assembly (dual-chamber auxiliary water reservoir with caps) designed for the electric and hybrid Denza N9 model. The part with catalog number OE 14451152-00 (auxiliary designation SZHA-1311010) is responsible for compensating changes in coolant volume and maintaining proper pressure in the vehicle's cooling systems.
The dual-chamber design allows management of separate cooling circuits (e.g., drivetrain, battery, or HVAC/heating), ensuring their optimal performance and thermal stability. Made from semi-transparent, durable plastic resistant to high pressure, temperature, and glycol exposure.
The product is brand new, supplied with dedicated pressure caps and original fittings, guaranteeing leak tightness and easy installation in place of the factory OE component.
