How-To Tuesday: Test Your Coolant for Electrolysis In 2-Minutes

Since you are going to be inspecting your coolant fluid to make sure it won’t freeze, you should go ahead and make sure to check for electrolysis as well.

The Two Minute Tech video below explains the process in detail, but basically you are just looking to see if your coolant is producing any voltage. If it has a charge, it can be eating away at expensive aluminum components in your car, which is never a good thing.
