Antifreeze Longlife

Concentrated Cooling Liquid with Long Lifetime

Wynn’s Antifreeze Longlife is a high quality concentrated blue cooling liquid with long lifetime which meets the actual normal standards and protects the cooling system against freezing and metal corrosion.

  • Protects against freezing and overheating of the cooling system.
  • Can remain in the cooling system during 2 to 3 years.
  • Protection against frost, depending on the concentration chosen (always dilute).
  • Contains a pH buffer which retards the acidification of the liquid and consequently prolongs its lifetime (2 to 3 years).
  • Can be readily used in combination with Wynn’s Cooling System Stop Leak.
  • Is compatible with other glycol based cooling liquids.
  • Meets all European and most International Standards.
  • Amine, phosphate and nitrite free.
  • Protects against rust and corrosion and especially against electrolysis and pitting of aluminium components.


Recommended for all “water” cooled systems of petrol and diesel engines.


Always to be used diluted in water, as a function of the exterior temperature expectations.
Can also be added to an existing cooling liquid in order to strengthen it. For optimal result, we advise cleaning the cooling system with Wynn’s Cooling System Flush when changing the cooling liquid.

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.
