The engine coolant recovery tank hose (also known as the expansion tank connecting tube or overflow tube) is an important connecting component of the automotive engine cooling system. Its core function is to connect the engine cooling system with the coolant reservoir/expansion tank, achieving dynamic balance of the coolant in a closed circulation system.

Installation Steps

• Drain Coolant: After the engine has cooled down, release the system pressure and drain part of the coolant.
• Remove Old Hose: Loosen the clamp, carefully remove the aged hose, and clean the interface.
• Install New Hose: Arrange it in the correct direction to avoid twisting or excessive bending.
• Tighten Clamp: Use stainless steel non-piercing clamps to prevent cutting the hose.
