What color is Prestone antifreeze coolant?

Newer coolants such as Prestone, based solely on the OAT chemical make-up, now offer a 10-year or 150,000-mile change interval thanks to their superior corrosion protection. Prestone is yellow, but many other coolant manufacturers use different colours.

B.

What color is the antifreeze?

OAT coolants are currently easily available from most auto parts stores. Hybrid Organic Acid Technology or HOAT: This coolant is usually dyed yellow but comes in other colors like green, pink, blue, red and orange, which leads to a lot of confusion.
  • What type of coolant is Dex cool?

  • Do you have to mix water with antifreeze?

    While water is the best fluid for cooling, it can cause corrosion. Buying an antifreeze that requires you to mix it with water can be a little more involved. However, it gives you more flexibility when it comes to mixture. Generally speaking, a 50/50 mixture of water and antifreeze is a good place to start.
  • How do you do a coolant flush?

    Draining the radiator alone normally should remove 40 to 45% of the coolant. After the first drain, fill the system as well as you can with water, then warm up the engine and let it cool. Drain the radiator again and fill it once more with water. Repeat.
