i found out today that my heater core o rings are indeed bad, i had high hopes it wouldn't be the case but it is.


I picked up a daily on my birthday as 60 dollars every three days wasnt going to cut it any more and i wanted heat haha.

 

Thank you Abran.... my plan was to re-create loop taking heater out of system... fill both heater hoses with vinegar ...plug... let work a day or two... then attempt flush again... "repeat as needed"...
