Last year I made the first of many gaffes on the forum stating antifreeze was all the same. Wrong. I learned OAT and EG are incompatible, after I topped off my clearly marked OAT reservoir with Glycol. I finally got around to cleaning out my cooling system today.

This vacuum purge and refill tool is sweet. I freaked out a bit when it didn't hold on the first pull, but noticed some of the hoses weren't quite flat. So I pulled the system again and it held at 21-22 inches. Same with the refill. The vacuum fell off before I had all the flush solution in. Another vacuum pull and it slurped up the rest of the solution.

The venturi assy connects with mini air chucks. Thinking I'll be adapting this thing for fast out drive vacuum tests.
