    brown coolant?

    My coolant keeps turning brown but no oil in it. What could be causing it? I flushed it about 4 times but it keeps turning brown. At the bottom when I drain is this red liquid that comes out. Once again, it's not oil. what could cause that?

    Red? Is you car a automatic? Tranny fluid from the cooler in the radiator maybe. Be low at the dip stick and tranny fluid show a slight pink haze if so.



    Really hope your car is a manual!

    Corrosion is cheaper than the other alternative, combustion fluids.

    Could also be corrosion with in the engine it's self. But a 2007 seems kinda new for that. Unless there was a poor coolant mix somewhere along the line, i.e. to much water ????

    could the gasket on the turbo be a culprit?

    Anywhere the coolant could meet either atmosphere, oil, or a combustion fluid can be a potential culprit, yes.

    GOOD NEWS EVERYONE! I did an engine block test with that engine block test liquid to check for exhaust or combustion fumes in the coolant system. It stayed blue the whole time. Better news its not oil, I used distilles water and its not separating.
    Further investigation shows, my coolant system is clogged up with bars leak. An abnormal amount. The only people who have touched this car are my mechanic and myself. I would never use a quick fix tool or anything as such to get around any problem. I never had a problem the car is still
    healthy. Now the only other person to touch my car is my mechanic at a performance shop. Hmmm...
