 What the Products Do

• Radiator: Dissipates heat from engine coolant to maintain safe operating temperatures.
  
• Coolant Hoses: Carry coolant between the radiator and engine, ensuring proper circulation under pressure.
  
• Mountings: Securely hold the radiator in place, preventing movement, vibration, and premature wear.

Together, they form a complete cooling solution that keeps your engine protected and performing as intended.

Symptoms of Failure

• Rising engine temperatures or overheating
• Coolant leaks around radiator or hose connections
• Bulging, cracked, or soft coolant hoses
• Rattling or loose radiator due to failed mounts
• Sweet coolant smell from the engine bay
• Low coolant levels requiring frequent top-ups

Common Reasons for Failure

• Heat & Pressure Cycles: Repeated expansion and contraction cause radiator and hoses to weaken over time.
  
• Material Aging: Rubber hoses harden or swell, while plastic mounts may crack.
  
• Coolant Quality: Old or contaminated coolant accelerates corrosion and internal damage.
  
• Vibration & Stress: Worn mounts allow radiator movement, leading to leaks and structural failure.

Why Replace as a Kit?

• Restores complete cooling system integrity in one service.
• Prevents breakdowns by addressing all common weak points at once.
• New mounts ensure secure fitment and reduced vibration.
• Protects against overheating and costly engine repairs.
• Saves labour costs compared to replacing components individually.
