Adding to my oil leak issues is my coolant. I remember months back, my coolant looked fantastic. The reservoir was clean and I had no sediment inside. About a month ago, my coolant light came on so I topped it up with distilled water. Haven't had an issue since. But I noticed my reservoir was all nasty inside.



It's not running hot and my heater still works great. Was hoping to find a thread on flushing out the system. From what I read about the CVCA engine, is a little different than the previous years. If anybody has a procedure for flushing 2015's out, can you please send it my way. Any other recommendations would be greatly appreciated.

Try the search function maybe with "heater core". I remember a pretty good write-up using a shop vac at the filler cap and removing a small hose for the make-up air. When my time comes that's the route I am taking, although I am a 2014 ckra. Good luck, John
