I want to flush my coolant soon because i have 92k miles and I want to flush it because I am not sure if the PO did it or not. I have read some of the archives, but I would like a comprehensive guide so I can make sure I don't screw anything up. I know I need a 50/50 mix of g12 and distilled water. The radiator drain valve is on the driver's side. I should flush the system when the car is completely cold. I should also open the radiator overflow cap so that air can escape too I think??? Cmon guys help me out. I have done as much research as I can at this point.
