Numb Nuts Coolant Questions - 6G75
« on: October 27, 2017, 12:15:43 PM »
What coolant do you dudes in the know use besides OEM for a 6G75 Gen 3? I couldn't find a good reference on facebook nor here.

Thanks!

The typical green Prestone or Zerex or the Zerex Asian. As long as it's not DexCool you should be good with any major brand - what's more important is the concentration, 50/50 works well but your cooling system will dissipate heat more efficiently if you run a 70/30 or 80/20 mix of distilled water/coolant. Your coolant concentration may need to be higher than that depending on the winter temps your vehicle will encounter - here in AZ it's not much of a concern.

Adding a couple drops of dish detergent to the coolant mixture will lower it's surface tension and allow it to transfer heat better.

Thanks! I just called a parts counter based on an MMUSA FB recommendation, they told me green is the answer.

Leo recommends Pentofrost or Aisin.
