1. IIRC, the flush mixture stays in for 20 minutes. Yes?
Something like that. Running.
2. Is it acceptable to use the lower rad hose as a drain? (Not being lazy, just my back is sore as the devil and I don't want to jack the car up andput a jackstand under it, to use the drain.)
Whatever you want. I ended up using a free flush method where the water was teed into the upper rad hose and I let it run out the normal fill spot. Made a heck of a mess, but rinsed pretty thoroughly! -- Jim
