Does coolant have additives?
Coolant has additives to prevent all of that electron swapping. But, as coolant ages, the additives are depleted and can’t do the job anymore. In fact, worn coolant becomes a pretty darn good electrical conductor, accelerating internal electrolysis. The good news is that it’s pretty easy to check the conductivity of your coolant with a digital multimeter that acts as a coolant tester. If the conductivity is high, it’s time for a coolant flush and fill. Here’s a quick way to check it.
Does coolant help with electrolysis?
Coolant also plays an important role in preventing corrosion caused by electrolysis. Electrolysis occurs when two dissimilar metals start swapping electrons, causing the metals to corrode. Since an engine has aluminum, copper, cast iron, steel and magnesium alloys, electrolysis will slowly eat away at its innards.
