Ok guys. I was a victim of a stuck thermostat about a month or so ago.... brought it to dealer they replaced thermostat.. now back to when I over heated in the backcountry. the very second I over heated I stopped and pulled off the side panels to inspect. First thing I noticed right off the hop is that my coolant changed color in the bottle.. to a dark green. Anyways brought this up to to the dealer at the time and they didnt seem to think it was a big deal.. Well I certainly do! Anyways since then they only replaced my thermostat and I have done 2 full coolant flushes. Coolant looks new for a couple rides and then starts to turn dark again with black oily residue in it. Here are some pictures of what my coolant looks like now. Its back at the dealer and I refuse to pick it up until its been fixed correctly. Im thinking bad head gasket or o rings... has anyone else had this issue or have any suggestions what it might be? Still under warranty. 2017 rmk assault.
