Your Guide to Prestone Technology

Prestone’s inhibitor technology is a one-stop product for all light duty vehicles, making it easy for you to choose it in your business. Here’s why:

  1. More thermally stable than commercial available ELC OAT AFC.
  2. Absolute compatibility with all modern engine metallurgy & polymers
  3. Absolute compatibility with all other Coolant/Antifreeze technologies
  4. Virtually non-depleting corrosion inhibitors for 10 years or 300,000 miles
  5. Unmatched cooling system protection for your car or light duty truck
  6. 7 years in development in Prestone Technology Centre
  7. 17 new patents
  8. 4 million mile fleet test

If you need to Top-Up existing antifreeze/coolants:

Prestone is backward compatible to be used in any light duty vehicle on the road today, including antiques, classic and new cars.

  1. Prestone inhibitor package permits topping off any antifreeze/coolant technology in any light duty vehicle on the road today
  2. Prestone Inhibitors help improve coolant/antifreeze by repairing the Stability & Corrosion Protection when it’s used to top up whatever coolant/antifreeze is currently in the system


Ethylene Glycol (EG), is by far the most common glycol used in coolant / antifreeze.

A 50:50 mixture provides:

  • Freeze Protection to -37°C
  • Boil Over Protection to +129°C

If you need to fill an empty cooling system:

A complete flush & refill using Prestone

  1. Instantly Layers & Protects the Entire Cooling System
    1. Some existing antifreeze/coolants take 4k to 5k miles to protect, whereas Prestone begins to work immediately.
  2. Stops the spread of Cavitation/Erosion, Corrosion, & Rust
    1. Ultimate Protection for Cooling System Metals & Polymers
  3. Helps Eliminate Corrosion By-Products
    1. Allows Optimum Heat Exchange

(Corrosion By-Products coat heat exchangers and reduce heat transfer)

We’ve conducted extensive testing to ensure Prestone coolant/antifreeze offers the best possible protection. It was 7 years in development in the Prestone Technology Centre and involves 17 new patents. The rigorous testing included 4 million miles of fleet testing against commercially available competitor.

Testing the protection of the water pump:

Our fleet testing showed that Prestone protected the water pump so that it was like new after 150,000 miles compared to others:
