Shortly after purchasing my 2013 RAM p/u, I checked the oil and coolant levels and saw the coolant was pink (5-yr.). The owner's manual stated that the p/u should have the purple, 10-yr. coolant. I took it to a shop to have the cooling system drained, flushed and the manufacturer's required coolant put in the system. When the coolant was drained, it was in fact purple. I had taken samples of the coolant prior to having it drained and put drops of it on white paper... it sure looked pink. Long story short, the system has the correct coolant in it.
