How do you do this? What exactly do you blow out? I have an 07 LS (Direct Drive). Which hoses do you blow through? Any have any pictures of this since a picture is worth a thousand words?

Take the two hoses off the engine that lead to the heater and blow compressed air through one of them until water won't come out anymore. One year I didn't use a compressor and I blew air into one tube and that works and I keep that to myself so you won't get a picture.

you could also pump antifreeze in the front line till it drains out the back line

Garn, I just posted pic's under the winterzation process thred under service and repair. It is for a V Drive But i would think they would come off the same spots as the D Drive does. You can blow them out with your mouth just don't pass out becasue that would be a bad story to tell everyone.
