I have a new-to-me 95 3.4L that really needs a coolant change. How much coolant amI not going to get out of the engine ifI don't pull the block drain plugs and knock-sensor? I just have this bad feeling thatthose plugs will leak when reinstalled, so I'd like to avoid it ifI can (lots of Ohio rust!)
With all my older cars, I used to just flush and re-fill the system with water a bunch until it flowed clear out of the radiator, letting it run to get hot so the heater core got rinsed too. A friend recently told me I'm not getting the block flushed well by using that method.
