What This Product Does:

• Transfers coolant through the cooling circuit to help remove heat from the engine.
• Supports proper coolant circulation, ensuring stable engine temperature control.
  
• Helps prevent overheating by allowing coolant to flow efficiently to the radiator and related cooling components.
  
• Provides a flexible, heat-resistant connection that absorbs vibration and thermal expansion.
  
  

Symptoms Of Wear Or Failure:

• Coolant may seep or drip from cracks in the hose or from the hose connection points, leaving residue or wet staining.
• A leaking hose can cause gradual coolant loss, requiring frequent topping up.
• Coolant loss or restricted flow can lead to overheating or unstable temperature readings.
• A sweet odor in the engine bay is a common sign of a coolant leak.
• Typical signs include cracking or splitting, swelling or bulging, hardened or brittle rubber, soft spots, coolant stains along the hose.
  
• If coolant circulation is affected, the heater core may not receive enough hot coolant.
• Low coolant or overheating warnings may appear if the hose begins to fail.

Why Replacement Matters:

• Prevents coolant leaks that can cause low coolant levels and loss of cooling system pressure.
  
• Helps avoid engine overheating, which can lead to severe and expensive engine damage.
  
• Restores proper coolant flow, ensuring efficient heat dissipation through the radiator and cooling circuit.
  
• Maintains reliable heater performance, since cabin heating depends on consistent coolant circulation.
  
• Protects nearby components, as leaking coolant can damage sensors, wiring, seals, and engine bay parts.
