Why We Do It

  • Extends the life of the engine cooling system.
  • Provides protection from rust and corrosion.
  • Prevents engine boil-over in summer (especially in traffic).
  • Prevents engine freeze-up in winter (especially in snow country).
  • The Bottom Line: Extends the life of the engine cooling system, and helps avoid costly repairs.

Why Does Antifreeze / Coolant Go Bad?

  1. Time
  2. Improper Care
  3. Incorrect ratio between antifreeze/coolant and water.*

* Ratio is supposed to be 50% antifreeze/coolant and 50% water.
