Note: Since the coolant expansion tank is a closely related part to the antifreeze, it is recommended to check the condition of the expansion tank while replacing the antifreeze.

When do you need to replace？

- The expansion tank is leaking.
- There is a blockage inside the expansion tank, which affects the normal flow of coolant.
- The expansion tank material is aged, cracked or damaged.

It is recommended to regularly check the appearance and function of the engine coolant recovery tank to ensure that it is not damaged or leaking.
Replacing the expansion tank and antifreeze at the same time will ensure the overall performance of the cooling system and extend the life of the engine.
