What This Product Does:

• Supplies hot engine coolant from the cooling system to the heater core.
• Enables cabin heating, since the heater core uses hot coolant to warm the air inside the vehicle.
  
• Helps maintain proper coolant circulation through the heater circuit for consistent heating performance.
  
• Provides a flexible, heat-resistant connection that handles vibration and thermal expansion without restricting coolant flow.
  
  

Symptoms Of Wear Or Failure:

• Coolant may seep or drip from the hose body or at the clamp connections, often leaving visible residue.
• A leaking heater supply hose can cause gradual coolant loss, requiring frequent top-ups.
• If hot coolant cannot reach the heater core properly, the heater may blow lukewarm or cold air.
• Coolant loss from the heater circuit can reduce overall cooling system efficiency.
• A noticeable coolant odor in the engine bay or cabin can indicate a leak in the heater hose.
• Common signs include cracking or splitting, swelling or bulging, hardened or brittle rubber, coolant staining around the hose.
  
• Low coolant or temperature warnings may appear if the hose begins to fail.

Why Replacement Matters:

• Prevents coolant leaks that can lead to low coolant levels and pressure loss.
  
• Maintains reliable cabin heating, since the heater core depends on a steady supply of hot coolant.
  
• Helps avoid engine overheating, as coolant loss reduces overall cooling system efficiency.
  
• Restores proper coolant circulation, ensuring stable engine temperature control.
  
• Protects surrounding components, since leaking coolant can damage wiring, sensors, and nearby engine parts.
