What ever you do, don't let anyone put Dexcool in your car.... A car I recently got back apparently that had a coolant leak in the past... Someone mixed Dexcool in with the green stuff that was in there.... This is what I had to deal with....
My friends dad mixed Mercedes Benz green stuff with Prestone and it created jello! He spent hours flushing it out. In non freezing climates, Mopar recommended Distilled water and the rust inhibitor supplement.
