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.

Routine Maintenance:

• Periodic Inspection: Visually inspect the hose condition during each maintenance session.
• Coolant Quality: Aged coolant accelerates rubber deterioration; it must be replaced according to schedule.
• Clamp Inspection: Ensure clamps are free from corrosion and looseness; replace as necessary.
• Avoid Contact: Prevent contact between oil, grease, and rubber surfaces.
