Description

Genuine Wynns · Part no. W45990

Safety: Danger. Causes severe skin burns and eye damage. Read the label before use.

Wynns CV Cooling System Flush W45990 is a 1L acid-free cleaner from the commercial-vehicle range, in a larger bottle for lorries and other commercial vehicles, made for any closed-circuit cooling system. It removes limescale, corrosion, sludge and oil residues and holds the dirt in suspension so it drains out with the old coolant.

Good to know

  • Why does dirt in suspension matter? Loosened scale that settles back can block the radiator core or heater; keeping it suspended means it leaves when you drain.
  • What do I do after the flush? Drain and rinse the system, then refill with the antifreeze the handbook asks for, mixed to the right strength, and bleed out any air.
  • Can it go in a car? It suits any closed-circuit system, but the 1L bottle is the commercial-vehicle size; a car is easier dosed with one of the smaller car-size bottles.

Which one?

For a car or van, the 325ml Wynns Radiator Flush (56064) or Cooling System Flush (45944A) are sized for smaller systems. When the system is clean and you need to seal a leak, follow with Wynns CV Treatment And Stop Leak 1L (W45690).

Key features

  • 1L acid-free cooling system cleaner
  • Removes limescale, corrosion, sludge and oil residues
  • Keeps dirt in suspension while cleaning
  • Safe for hoses, seals and all metals
  • Works with OAT coolant
