How to do a coolant flush???
I have an 04 Grand Am SE 2.2L ecotec 4 cyl. and would like to know the
proper steps in doing a coolant flush. I have done many in the past but on
other, different vehicles. I was reading something about a drain plug on the
engine block to go along with the drain plug (or petcock) on the radiator. Any
help would be greatly appreciated. Thank you.
