 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.       
Ideal For: Cooling system overhauls, resolving overheating or leaks, and preventive maintenance on performance-driven or high-mileage vehicles.

Kit contains a Mahle radiator and Original Porsche hoses and mountings
