Condition Bus Engine Spare Parts Expansion Tank Assembly for Yutong Higer Kinglong WB131100510

Part Number: WB131100510 is a professional-grade Expansion Water Tank Assembly manufactured by Wanbon (WB), specifically engineered for heavy-duty cooling systems in large and medium-sized coaches and city buses. As a critical component of the engine’s coolant management system, this reservoir tank ensures stable thermal performance by accommodating coolant expansion, releasing air from the circulation loop, and enabling real-time monitoring of fluid levels. Designed to meet the demanding operational requirements of modern commercial fleets in 2026, it supports reliable engine temperature control under continuous high-load conditions—such as long-haul intercity routes or frequent stop-start urban transit cycles. With features like pressure regulation, anti-foaming internal structures, and integrated electronic sensing capability, the WB131100510 delivers superior durability, safety, and system efficiency across major Chinese bus platforms.

Parameter	Detail
Pressure Regulation	Integrated pressurized cap with opening pressure set between 1.1 bar and 1.5 bar, preventing premature boiling and protecting hoses from burst failure
Temperature Resistance	Operates reliably in extreme environments: -40°C to +125°C; resistant to thermal deformation and embrittlement
Liquid Level Monitoring	Equipped with an electronic sensor interface for real-time transmission to dashboard warning system; triggers “Low Coolant” alert when level drops below minimum
Anti-Foam Design	Internal baffle plates and flow guides minimize coolant sloshing and turbulence, reducing air entrainment and ensuring smooth pump feed
Coolant Compatibility	Optimized for use with modern OAT (Organic Acid Technology) coolants; internal surfaces treated to resist corrosion and chemical degradation
Structural Durability	Meets heavy-duty vibration and impact standards; designed for service life exceeding 300,000 km under normal operating conditions
Connection Ports	Standard hose fittings for overflow, return, and ventilation lines; compatible with OEM routing layouts
