I have a Denali XL and I took it in to have the 100k service performed and the mechanic told me that I had oil in my radiator, probably from a leak in the oil cooler attached to or in the radiator. He suggested that the radiator, oil cooler and all related hoses be replaced. Would this be the correct diagnosis or should I get a second opinion.
