Product Details

• Functions: Made from durable PA plastic materials, this expansion tank withstands extreme heat and vibrations. It helps reduce oil dilution, cylinder wear, fuel consumption, and exhaust emissions while improving the heating system's efficiency
• How it works: The automobile expansion tank, also known as an antifreeze reservoir or water reservoir, is a vital component of the cooling system. It stores coolant discharged from the engine. When the engine heats up, the coolant expands and releases excess pressure. As the engine cools, the fluid flows back into the radiator to maintain proper operation
