Refilling is a completely different matter, and is recommended to use a vacuum fill system.
You're never going to get all 6 gallons out without some major diss-assembly or repeated use of a vacuum system to draw coolant out of the very difficult to reach spots. The most I've ever managed with the above procedure is about 5.5 gallons.
Jacking up the front end doesnt help as there are too many bends and pockets for coolant to get trapped. I recently drained my coolant three times to fix a leak and let me tell you....the best advice is to purchase a airlift system for draining. uview airlift 550000000000 I will look for a few past posts that helped me. BTW, I developed a system that is pretty good, although time consuming.
Thanks, I drained it today, still only got 4-4.5 gallons out of it. I drained it through the two large aluminum pipes that I guess go to the coolers, the little one that runs next to them, the tiptronic oil cooler, and the two pipes that is located near the right rear wheel. And a T connection to the large ones in the middle.
I am sure there still are some coolant left in front of the car. I just hope there isn't enough of it to freeze once the winter hits us. I guess it is mostly water, which is not good. At least the engine is properly drained!
Thanks for your help!
