How do you guys pressurize this stuff to check it?

Dmichels

make a simple hose gauge set up
look at what I did http://i1358.photobucket.com/albums/q777/DaveMichels/IMG_1876_zpscf1f10f9.jpg
Pressurize with an air hose to 10 to 15 lbs, use water and look for bubbles

Thanks, I can do that for the heater core. What do you do about the evaporator though?

Dmichels

Same deal you just need to get a little more creative with the hose hook up.
