    Help! C5 S6 Multiple leak(PS, coolant)

    Guest-only advertisement. Register or Log In now!
    Earlier today, I found some fluid on the garage floor. Based on color, looks like power steering fluid and coolant.

    Pink coolant fluid is found under transmission casing(see pics below) Seems to be leaking from somewhere above the transmission.


    PS fluid is found on the bottom of the radiator(driver side). and hoses around it. See pic shown.




    Any idea what parts went wrong? Thanks!!

    Coolant coming from the lines that run behind the engine? The coolant temp sensor is behind the engine on the passenger side and have a tendancy to fall somewhat regularly. There is an o ring that seals the sensor in place - perhaps that has gone bad. As well, check where the pipe connects to the block - could be a bad gasket.

    The trail of coolant looks like it's drivers side, just above/ in front of the axle? If so that's the coolant reservoir overflow. Kind of normal to find some races of coolant running down from there. It's a *keep an eye on it* type of situation. It shouldn't overflow much fluid and not very often. But occasionally it will.

    The power steering leak is THOSE CLAMPS on the hoses.All those 'crimp' clamps need t be cut off and replaced with good adjustable clamps everywhere you find them. There are some on the hoses under the steering fluid reservoir too. Get rid of those.

    Yea. It's at driver side above the axle. Reservoir overflow meaning excess fluid will run out when the system is hot. is that right? Well, my coolant level when hot it below the min line. And I've been driving it for the past two days. Coolant level is dropping slowly. guess somewhere is leaking.

    CLAMPS! Yes, I will have them replaced. Thanks!!
