Function of the Heavy-Duty Truck Expansion Tank
The expansion tank (also called a coolant reservoir or overflow tank) in a heavy-duty truck serves several critical functions in the cooling system:
Coolant Expansion Accommodation - As the engine heats up, coolant expands in volume. The expansion tank provides extra space to prevent excessive pressure buildup in the radiator.
Coolant Storage & Replenishment - When the engine cools down, coolant contracts, creating a vacuum that draws stored coolant back from the tank into the radiator, maintaining optimal coolant levels.
Air Bubble Removal - Helps separate air pockets from the cooling system, improving heat transfer efficiency and preventing overheating.
Pressure Regulation - Works with the radiator cap to maintain system pressure, raising the coolant's boiling point for better thermal performance.
Coolant Loss Prevention - Captures overflow coolant instead of letting it vent out, reducing waste and environmental contamination.
Coolant Level Monitoring - Allows visual inspection (via marked "MIN/MAX" levels) to ensure proper cooling system function.
In summary, the expansion tank ensures stable coolant circulation, prevents overheating, and prolongs engine life in heavy-duty trucks.
