No, it is just a good rule of thumb to not mix different coolants/color coolants. Ma Mopar is using a HOAT type coolant which has different inhibitor properties than standard ethylene glycol (green coolant). If you are going to use a different coolant, make certain to flush the coolant system first just to be safe. I know mixing Dexcool (GM coolant) with ethylene glycol will coagulate in the block when heated to operating temperature, it happened to my dad in a used Caddy he bought.Can you mix coolant? My radiator coolant is green reserve is pink.
