Hello, in the engine meiens 2001er V70 2.4 Turbo there is a hard plastic hose. It goes from the cooler (below the headlight on the driver side) to the middle of the engine block and then runs (I suppose) under the engine. A hose from the same hard plastic material also runs directly across the engine block. At first mentioned I found an oil film directly where it is flanged to the cooler (beside / below) from the driver’s headlight. What is this for an S Chill or pipe? Does the oil film belong there? Looks like engine oil!?!?!? Thank you !!
