Buying Guide

Keeping your engine cool is essential for a smooth ride. Choosing the right coolant can prevent costly problems. I once learned this the hard way during a summer road trip!

Here’s a guide to help you choose the best engine coolant:

  • Vehicle Compatibility:
    Make sure the coolant is right for your car. Some coolants work with all vehicles. Others are made for specific makes or models, like GM or Kawasaki.

  • Coolant Type:
    There are different types of coolants, like 50/50 prediluted and concentrated. Prediluted coolants are ready to use. Concentrated coolants need to be mixed with water.

  • Longevity:
    Consider how long the coolant lasts. Some coolants last for 5 years or 300,000 miles. Others can last up to 15 years or 500,000 miles.

  • Protection:
    Look for coolants that protect against rust and corrosion. These protect your engine parts. Some also have a bittering agent to make them taste bad, for safety.

  • Special Features:
    Some coolants are designed for specific uses. For example, some are made for motorcycles. Others use organic acid technology (OAT) for extra protection.

  • Color:
    Coolants come in different colors, like yellow, purple, and blue. Color can help you spot leaks easily.
