Good Afternoon,

Has anyone done a vacuum check on their cooling system to check for leaks?

If so, how long did it take to get the vacuum?  I'm using a Maddox system to vacuum and been running for 40 minutes with no movement on the gauage.  I did check the device and it is working.  I know AC systems can take 30-45 minutes so I assume a 5-gallon cooling system should take longer.

If you are pulling no vacuum, then it is leaking at the tube that feeds the overflow tank.  The fitting you are using is not blocking the tube off and you are never going to get anything as you are sucking on the world.  block off the tube or take hose off that goes to the overflow tank and try that.  It does not take hours to pull such a vacuum.  it's minutes.
