That is a lot, make sure to keep an eye on the overflow so you don't get more air back into the system, but it should come out. You will have to keep an eye on that overflow bottle for a few days depending on your drive.
Scotty you and I grew up during the same time, back in the early 80's my summers were either spent out with my Dad while he worked on aircraft or at the library with my Mom since that was where she worked. I used to know the Dewey Decimal system like the back of my hand. I wish schools these days had Vocational schools, I grew up in a town of about 40K and our school had Marine repair where I learned to TIG, Metal shop, Auto mechanics, Drafting (boy I am glad I didn't waste my time with that, although I started designing with Acad 12 lol), we had Electronics (worst electronics teacher EVER, very funny stories about him, like the time he connected a lamp cord to a Sparkomatic 6 band EQ then proceeded to plug it into the wall. I went to the principle over that one). We also had Autobody and FFA stuff there were a lot of things to learn about that were practical. Now those programs it seems are gone. But I digress.
Sorry to take over your thread Shawn but it sounds like your getting close. If you really want to learn what is going on with these cars your going to want to get a device to see live data like we mentioned previously, it will tell you more than you need to know but it's almost better than a box full of tools sometimes. Buy a set of tools at Harbor Freight, you don't need a super expensive tool set to get the job done in most cases. Look for their super coupons and 50% off sales.
