Alright guys I put a RKT drop in kit on my 13. Got about 75 miles on so far. I bled the coolant system. Took it out and the coolant level held. Have a second day on it and the level is all of a sudden down like an inch. I did reuse the base gasket when I installed. There was zero miles on the sled. Could that be my problem. I cant really see any major leaks.
