What This Product Does:

• Transfers coolant to and from the coolant reservoir
  
• Helps maintain the correct coolant level and circulation
  
• Supports proper cooling system pressure regulation
  
• Prevents overheating by ensuring consistent coolant flow
• Helps the engine cooling system operate efficiently

Symptoms Of Wear Or Failure:

• Coolant leaks near the reservoir or under the vehicle
  
• Low coolant warning light or repeated coolant top-offs
  
• Engine running hotter than normal
• Visible cracks, splits, or swelling in the hose
  
• Soft, spongy, or brittle rubber texture
• Coolant residue or dampness around hose connections
  
• Sweet coolant smell from the engine bay
  
• Steam from under the hood (in severe cases)
  
  

Why Replacement Matters:

• Replacing a worn or damaged lower coolant reservoir hose is critical to maintaining proper cooling system performance. This hose helps regulate coolant flow between the reservoir and engine, ensuring consistent pressure and temperature control.
• Over time, heat and pressure can cause the hose to crack, weaken, or leak. If not replaced, a failing hose can lead to coolant loss, overheating, and potentially severe engine damage. Prompt replacement helps prevent breakdowns, protects vital engine components, and ensures long-term reliability.
• Installing a new hose restores proper coolant circulation and helps keep your engine operating at a safe and stable temperature.
