engine overheating

Mixing coolant for your car is relatively easy. To do so, you’ll need a name-brand coolant that is compatible with your vehicle, distilled water, a clean measuring vessel, a large, clean storage container that can be closed or sealed, and a funnel (optional). It is important that you use distilled water, as non-distilled water will accelerate corrosion in your cooling system. With all of that ready, here’s how to mix coolant:

  1. Check the coolant capacity listed in your vehicle’s owner’s manual
  2. Measure out the correct ratio (listed below) of coolant into clean storage container
  3. Measure out the correct corresponding ratio (listed below) of water into the partially filled storage container
  4. Mix thoroughly
  5. Store in a cool, dry place
  6. Use as needed

Coolant-to-Water Ratio Guide

Different type of engine coolants require different coolant-to-water ratios. Which type of coolant you use depends on the type of vehicle you have and the type of environment you drive in. Each ratio is listed below, with the first number indicating the type of coolant and the second number representing water.

  • Antifreeze – 1:1 or 50/50
  • Ethylene-glycol – 7:3 or 70/30
  • Factory – 6:4 or 60/40
