I just did this tonight! I'd like to add onto the How-To. I'd recommend getting an extra long hose to run from your bottle pump to the fill hole and secure tubing to the exhaust using a zip-tie so you don't need to hold it. Lower the car so she's level, lay down and watch for the overflow to run out. I found that if I leave the car jacked up on the passenger side it takes about a half qt extra that ends up being spilled into your drain pan once you lower it to let the over flow drain out. Fyi.
