So, I finally got this thing filled tonight. I'm running an 85%/15% mix of distilled water and DexCool. I know DexCool isn't the best thing out there, but I already had some (drive a GM truck) and the local VW dealership wanted $22.00 for a gallon of VW branded Pentosin G11. I only needed 3 or 4 ounces, so it didn't seem worth it.

Anyway, here's the question - should I run the pump and intake fan overnight to help bleed the system while running a leak test? I've been running the pump on and off for 10-15 minute cycles to help the air bleed out the T line. The pump and fan are powered off a hobby grade 30A AC/DC power supply, so it can handle the action. Should I keep the fan on to keep the pump cool? Seems to make a pretty large difference.

EDIT: Should I close the top of the fill tube while bleeding? (using a DD fillport) Does it even matter right now?

Thanks in advance, and thanks for the huge base of knowledge to read. It has made this 'project' rather enjoyable, and I'm not even there yet.

Here's a pic. Don't beat me up too bad on the undersized Rad or the tubing layout...I know it isn't perfect.
