Engine coolant recommendations

mile marker 27 · Sep 27, 2025 at 2:56 PM

I know the ELC(extended life coolant) is what the consensus is. If an engine has the original green coolant in it, should it be drained and replaced with ELC or can an additive, that actually works, be added? I’ve used the Napa(Wix) coolant treatment before, with the regular green, in the past but really not sure if it’s mitigating the potential of electrolysis.

my info may be outdated but as I was told, if you have some green in your system test and treat on a regular basis.

Is the treatment I suggested, sufficient?

Man I wouldn’t be messing around with permanent antifreeze. Put premix ELC in it and be done.
