How do you guys make sure the heater core has been winterized?

I use my air compressor to blow air through the hoses. Remove both hoses from the engine, put one in the bilge area and blow air into the other line until all the water comes out. I have been doing this every year since 2001.

You can also use a wet/dry vac. It's what I do to assure water is out of the ballast plumbing.

Hope this helps
