2010 CL 63
oil in coolant
Hello folks
Been trying to find out why I have oil in my coolant, read all comments in all and any MBZ forums. Most everyone suggested, head bolts, head gasket, radiator, ...etc. Well, let me tell you folks of my story. I got a 2010 CL 63 oil mixing in the coolant tank, long story short, I was too lazy to put coolant so I used water for about 3 months. the water caused corrosion in my heat exchanger, (located under right fender), had it tested by a radiator shop the 1st time and it look good, scratching my head, so I asked the rad. shop to wash out the old oil in the cooler and retest, sour thing. once we connected air to it and submerged the cooler in water bubbbbbles. don't let anyone talk you into head job, or head bolts, test your cooler. eazy to pull out, test and its only $250. end of my story. thank you all.
