• 【Material & Function】The overflow tank reservoir is made of safe, high-quality PP plastic material, which can withstand excessive heat and vibration, and its function is to store excess coolant when needed, which helps to reduce oil dilution, fuel consumption, cylinder bore wear, and tailpipe emissions, and improves the efficiency of the heating system. The level of antifreeze inside can be seen directly without opening the radiator cap, avoiding damage to car parts.
• 【How It Works】 Automobile expansion tank is commonly known as the antifreeze reservoir tank, water reservoir tank, is an important part of the cooling system. It contains coolant discharged from the engine cooling system. When the coolant is at a high temperature and expands through the radiator, or there is an excess of coolant, pressure builds up and is released. After the engine cools, the excess fluid flows from the vehicle's coolant tank back to the radiator.
