Description

Genuine Wynns · Part no. 25541

Safety: Danger. Causes serious eye damage. Read the label before use.

Wynns Extreme Cooling System Degreaser 25541 is a 325ml cleaner for a cooling system contaminated with oil, the brown mayonnaise-like sludge left when a heat exchanger or cylinder head gasket has leaked oil into the coolant. It degreases the system and holds the residue in suspension to drain out.

Good to know

  • Why is there oil in my coolant? Oily or creamy sludge in the coolant usually means oil is getting in through a leaking oil cooler or head gasket, which should be fixed before the system is cleaned.
  • Will one treatment be enough? Heavy contamination may need draining, rinsing and treating again until the coolant runs clean before the final refill.
  • Is it safe on hoses and seals? Yes, it is safe for rubber hoses, seals and all metals, and works with every type of coolant including OAT.

Which one?

For ordinary scale and rust without oil, Wynns Cooling System Flush (45944A) or Radiator Flush (56064) is the right cleaner. To seal a small head gasket leak once the system is clean, Wynns Cooling System Stop Leak (45644A) follows on.

Key features

  • Removes oil and sludge from the cooling system
  • For leaking heat exchanger or head gasket contamination
  • Keeps residues in suspension
  • Safe for hoses, seals and all metals
  • 325ml bottle
