Diagram Ref No 23

What This Product Does:

• Vents trapped air and coolant vapour from the cooling system.
• Helps regulate cooling system pressure as temperatures rise and fall.
  
• Routes overflow coolant between the expansion tank and the main cooling loop.
  
• Prevents air pockets that could reduce coolant circulation and cooling efficiency.
  
  

Symptoms Of Wear Or Failure:

• Cracks or loose fittings may cause coolant seepage near the vent line or expansion tank area.
• A leaking breather line can gradually reduce coolant levels, requiring frequent top-ups.
• If the line cannot vent properly, excess pressure may build up in the cooling system.
• Low coolant or overheating warnings may appear if leakage or pressure issues develop.
• A noticeable coolant odor in the engine bay often indicates leakage from the vent line.
• Common signs include cracking or splitting, brittle or hardened material, damaged connectors, coolant residue buildup.
  
• Air entering the cooling system or improper venting can reduce cooling efficiency.

Why Replacement Matters:

• Prevents coolant leaks that can lead to low coolant levels and reduced cooling performance.
  
• Maintains correct venting, allowing air and vapour to escape and preventing pressure buildup.
  
• Helps avoid engine overheating, since trapped air or coolant loss can disrupt circulation.
  
• Prevents air pockets in the cooling system, improving heat transfer efficiency.
  
• Protects surrounding components, as coolant leaks can damage wiring, sensors, and nearby engine parts.

Diagram Ref No 20

What This Product Does:

• Carries coolant between key cooling system components
• Helps maintain proper coolant circulation and temperature control
• Features a quick-release coupling for fast, secure hose connection
  
• Provides a leak-resistant seal under pressure
• Supports efficient cooling system operation and prevents overheating

Symptoms Of Wear Or Failure:

• Coolant leaks near the hose or quick-connect fitting
  
• Low coolant warning light
• Frequent coolant top-offs
• Engine overheating or rising temperature gauge
  
• Sweet coolant smell from the engine bay
  
• Steam from under the hood in severe cases
  
• Cracked, swollen, or brittle hose material
• Loose or improperly seated quick-release connection
• Coolant residue around the coupling area
  
• Connection popping loose under pressure (in advanced failure)
  
  

Why Replacement Matters:

• Replacing a worn coolant hose with a quick-release coupling is important because it ensures a secure, leak-free connection and proper coolant circulation throughout the cooling system. Over time, heat and pressure can cause the hose material to weaken, while the quick-connect coupling seals may wear out.
• If the hose or coupling fails, coolant can leak or the connection may loosen, leading to coolant loss, poor cooling system performance, and engine overheating. Even small leaks can reduce cooling efficiency and increase strain on other components.
• Installing a new hose helps restore proper coolant flow, maintains a tight coupling seal, prevents overheating, and protects the engine from costly damage.

What This Product Does:

• Transfers coolant (antifreeze) between engine components
• Regulates engine temperature by maintaining proper coolant flow
  
• Prevents overheating by helping move heat away from the engine
  
• Supports cabin heating by routing warm coolant to the heater core
  
  

Symptoms Of Wear Or Failure:

• Coolant leaks or visible fluid under the vehicle
• Engine overheating or rising temperature gauge
• Low coolant warning light or frequent coolant top-offs
• Sweet coolant smell from the engine bay
• Steam coming from under the hood
• Weak or no cabin heat
• Cracks, swelling, or soft/brittle hose material
• Coolant residue or dampness around hose connections

Why Replacement Matters:
Replacing a worn coolant hose is essential to maintaining proper engine cooling and preventing costly damage. A failing hose can lead to coolant leaks, overheating, and reduced heater performance. If left unaddressed, it may cause severe engine overheating, which can result in serious repairs such as head gasket failure or engine damage. Installing a new hose helps ensure reliable coolant circulation, stable engine temperature, and long-term vehicle performance.
