II recently inherited a 99 buick regal. I noticed it was running a little hot. When I checked the radiator I saw brownish water and the cap had a brown mud like substance on it. I was told it was probably some sort of sealer. Maybe for a heater core or some other sort of leak. Shouldnt there be radiator fluid in the radiator. Instead of the brownish water. And how do I go about fixing it?
have the same problem?
