Description

If you’re refreshing coolant or sorting out a neglected cooling system, a proper flush can help remove built-up deposits that reduce cooling efficiency. Mannol Radiator Flush is designed for water-cooled engines and helps clean the radiator and cooling passages before you refill with fresh antifreeze/coolant.

What It Helps With

  • Helps remove rust, scale and deposits from the cooling system
  • Helps clean internal cooling passages and the radiator core
  • Useful before changing coolant type or after unknown service history
  • Can help improve heater and cooling performance where contamination is present

How to Use

  • Add the contents to the cooling system.
  • Turn the heater to hot and run the engine to operating temperature.
  • Allow to circulate, then drain the system and flush with clean water.
  • Refill with the correct coolant/antifreeze mix for your vehicle.

Compatibility

  • Suitable for most water-cooled internal combustion engines.
  • Safe for common cooling system materials (metals, alloys, hoses and plastics) when used as directed.

Notes

  • Always follow the instructions on the bottle.
  • If the system is heavily contaminated (mud, oil contamination, severe corrosion), a deeper clean and component inspection may be required.
