Coolant Expansion Tank Coolant Expansion Tank Cap For Hyundai Tucson 2021-2024 Engine Coolant Recovery Reservoir Expansion Car Tank Overflow Bottle Reservoir Tank

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.

• Functions : Using stable and outstanding PA plastic materials can withstand excessive heat and vibration. Helping to reduce oil dilution, cylinder bore wear, fuel consumption, exhaust emission, and improving efficiency of the heating system.
• Function : When the coolant pressure in the radiator exceeds the pressure cap setting, the coolant is sealed through the pressure cap and flows through the overflow tube into the radiator coolant overflow tank.Bottom port is radiator overflow,the top port is the tank overflow.
• High Quality : The coolant reservoir tank replacement is manufactured from quality materials to withstand the stresses of underhood heat and engine vibration. It is thoroughly tested to ensure performance and long lasting quality over time.
• Coolant Reservoir Features : This coolant overflow tank is made of high quality PP material, which helps to reduce oil dilution, fuel consumption, prevent oil leakage and reduce the pressure of car cooling system. You can directly see the internal antifreeze level without opening the radiator cap to avoid damaging parts.
• Simple Installation Using Factory Points Designed with original equipment dimensions and mounting points for a straightforward, no-modification installation. A practical choice for those with basic mechanical skills looking to perform their own maintenance
