While traveling home, low oil level light went on. Checked oil and it’s low. Added oil and 1 hour later the low oil level light was on again. Stopped and had it checked and found the oil and coolant mixed in the cooling system bottle. Built in oil cooler inside radiator leaked oil into cooling system. Dealer replaced radiator with oil cooler, all hoses and flushed system.
