Just discovered an oil/oily residue in my radiator overflow tank. I had the oil changed last week and they informed me that the oil that they drained did not any water/anti freeze in it. What could be the cause of my oily radiator?

Hi there,

Keep an eye on the oil & coolant, do a coolant flush with a cleaning agent to try and remove as much oil residue as possible, if this continues you may have a head or gasket problem developing.
