    Leak from the engine

    Hello,

    Today, I noticed something leaking from my engine. I don't know what it is or where in the engine it came from.



    Anyone know from the color? Thank you so much in advance.

    How does it react when adding a few drops of water?

    Guess: Coolant.

    Couldn't test it. Sorry. I know for a fact that there's a small oil leak from thr block, but Im not sure if this is related.



    I took this picture if it's any help.

    Not the greatest detail in the photo. I also noticed that after a couple hours, it evaporated. I don't think it is oil, so either coolant or water.

    Looks like a green tint to the liquid, that is bad stuff if your coolant is green. It should be blue, BMW blue cut with distilled water to be exact.

    There are a couple of coolant hoses back in that area, and they goto the heater.

    Pop the hood and have a look for 1 of the hose clamps could have loosen or you have a bad hose.

    Prob a heater hose gone - your valve will be right in that area along the frame rail.

    Looks like coolant mixed with water now that I look at it.
