93 LeSabre - brown oily film in overflow jug
There is a brownish-oily feeling film approx. 1/2" thick laying on top of the antifreeze in the coolant overflow jug on my moms 93 LeSabre. Anyone ever see this before? I have a hunch that it's tranny fluid and that there is probably a leak inside the radiator tank. Any input would be greatly appreciated!
