Expansion Tank 812W06125-0001
812W06125-0001 is a specialized expansion tank (coolant reservoir)
assembly designed for heavy-duty trucks such as the Sinotruk Howo
T7H and SITRAK C7H. As a crucial component of the vehicle's cooling
system, it serves essential functions.
Product Function
1.Cooling System Pressure Regulation
The primary function of the expansion tank is to regulate the
pressure within the cooling system. When the engine is running, the
coolant expands as it heats up, increasing in volume and pressure.
The tank accommodates this excess coolant, preventing excessive
pressure that could damage components. When the system cools down
and the coolant contracts, the tank supplies coolant back to the
system, maintaining a full cooling circuit.
2.Air Bleeding (Deaeration) Function
The tank serves a vital air bleeding function. It collects air
bubbles and vapor formed within the cooling system and vents them
out, ensuring no air pockets remain. This improves cooling
efficiency and prevents issues like cavitation and localized
overheating.
3.Coolant Level Monitoring
The tank features clearly marked level indicators (MIN/MAX lines),
allowing for easy visual monitoring of the coolant level. This
facilitates quick identification of low coolant levels or potential
leaks, simplifying maintenance.
Main Purpose
1.Engine Cooling System Support
The tank is primarily used in the cooling systems of engines for
Sinotruk Howo T7H and SITRAK C7H heavy-duty trucks. It is essential
for maintaining the engine within its optimal operating temperature
range under all working conditions, preventing both overheating and
excessive cooling.
2.Routine Vehicle Maintenance
The easy visual level check enables simple daily inspection and
top-up of coolant, helping to identify cooling system issues early
and ensuring reliable vehicle operation.
3.Specialized Vehicle Compatibility
This product is specifically designed for compatibility with
heavy-duty truck models like the Sinotruk Howo T7H and SITRAK C7H.
It is an OEM (Original Equipment Manufacturer) grade part,
guaranteeing perfect integration and reliable performance with the
vehicle's systems.
