Stop in for a cup of coffee

Nothing wrong with it in a OEM used system. I just draws water in. Take a ounce in a cup leave it out over night you will have a ounce and a half of fluid in it. You should never mix glycol based and silicone based. Friend had all his rubber basically double in size when he mixed them. Expensive mistake for him early Hudson. Bet Craig @mobileparts can chime in on this. Or Frank probably knows also.
