Yes I already had the leak. Discovered it by it overheating one day. From that point on I've just been filling it every time I drive and it's it about 5 miles at a time to from work and store but it used to just come from the front leaking out on the ground but now it seems like it goes to the back. It never did it until we got -1 degrees over Christmas but I put in antifreeze and drove it so it would get into hoses. Could a freeze plug have popped? This started so much right after the cold that I thought rain froze under the van on inside the bumper or line a leak around the back doors. It leaks normally anyways but I was assuming because we got a ton of rain then what they called a "flash freeze" but it hasn't stopped leaking there yet.
