Virtually all automobile and light-duty truck cooling systems can benefit from the cooling system protection of Havoline Extended Life.

With patented carboxylate inhibitors, Havoline Extended Life provides:

  • Outstanding high temperature protection of cooling system metals including aluminum
  • Organic additive formulation that is free of silicate, nitrite, borate, phosphate, nitrate and amines, allowing longer service life
  • Extraordinary extended life cooling capabilities for up to five years or 150,000 miles

Havoline® Extended Life meets European spec phosphate-free requirements and Japanese spec silicate-free requirements and was the first to earn GM's own DEX-COOL requirement approval. We also offer Havoline Extended Life Prediluted 50/50 for those who wish to have coolant already mixed with deionized water.
