Product Detail

WG9112530333 Expansion Water Tank for SINOTRUK HOWO

The WG9112530333 Expansion Water Tank Assembly is a critical cooling system component designed for SINOTRUK HOWO heavy-duty trucks. It is a rear-mounted small water tank that absorbs the volume changes caused by coolant thermal expansion and contraction, maintains stable system pressure, and separates air bubbles in the cooling water to prevent cavitation of the water pump and maintain heat dissipation efficiency.

Thermal Expansion Buffer: Provides a "buffer space" for engine heat dissipation to prevent overheating and ensure stable cooling system operation
Air Bubble Separation: Effectively separates air bubbles in the cooling water to prevent water pump cavitation
Durable Construction: Made of high-temperature resistant material with anti-aging properties and tight sealing
Level Visibility: Liquid level is directly visible for easy coolant level monitoring
Compatibility: Direct replacement for original SINOTRUK part, ensuring perfect fit and function

Item	Details

Function Description

The expansion water tank plays a vital role in the engine cooling system. It absorbs the volume changes caused by coolant thermal expansion and contraction, maintains stable system pressure, and separates air bubbles in the cooling water. This prevents cavitation of the water pump and maintains heat dissipation efficiency. The tank provides a "buffer space" for engine heat dissipation to prevent overheating and ensure stable operation during long-term and high-intensity operation.
