I just changed my water pump and I went to fill the antifreeze and it just sits there in the tank. It won't go anywhere at all. I let the car run like 20 minutes to get up to temp, and still nothing!! Am I doing something wrong? Has anybody else come across this?

engine type would be a great help.

It's the 4 cylinder 2.0 manual transmission

Sounds like air got into the system when you changed the waterpump.

This was posted a couple days ago on contour.org. I honestly thought it was you since the guy is having the same issues with his V6. I suggest trying what people have suggested.
