I have a general question for the procharger guys: after you run antifreeze thru your motors do you drain or keep the antifreeze in your intercoolers? I want to make sure I winterize my intercooler the correct way don't want any surprises in the spring.

I drain my intercooler first then run anti freeze thru it and leave it in there till spring. Hoping for some corrosion protection.

What kind of antifreeze is recommended for this? Are some RV antifreezes better than others for the intercooler?

none of the RV anti freeze have any corrosion protection...I use reg anti freeze, run on hose before putting in water..so all flushed out..
