Hey yall. Working on my Mom's 2015 2.0l. She has oil in the coolant reservoir & all of the coolant hoses ae swollen up with what seems like oil seeping out of them. There is no coolant in the oil. I plan on flushing the system, replacing the hoses, & replacing the thermostat, but am not sure what is causing the problem. Has anyone else dealt with this? Thanks for your help.
