Cooling System

Cooling system problems, such as leaks and insufficient cooling due to fouling of the system, are the primary cause of vehicle breakdowns. To prevent these problems Wynn’s recommends radiator treatments.

Wynn's Extreme Cooling System Degreaser removes oil and sludge in the cooling system of vehicles.

  • Removes oil and sludge in the cooling system (caused by a leaking heat exchanger or cylinder head gasket).
  • Degreases and cleans the entire cooling system.
  • Keeps the residues in suspension whilst cleaning.
  • Restores the optimal operation of the cooling system.
  • Excellent performance in all types of cooling liquid, including OAT coolant.
  • Is completely soluble in water.
  • Safe for rubber hoses, seals and all metals in the cooling system.

APPLICATIONS

For all “water” cooled systems of petrol, diesel and LPG engines.

Add Wynn’s Extreme Cooling System Degreaser directly into the radiator or via the expansion tank if part of the system circuit.
Warm up the engine with the heater control in HOT position.
Let the engine run at idle for 20 minutes.
