No answer for the Radiator flush?
Leme try again then...
How do you guys approach your flush. Do you do it manually with Tap or mechanically using a filter and distilled? Cause I had a thought when checking out Martin's blog and there is a pic of a Chip Block being flushed with Tap water, followed by a YT vid of a Corroded and Calicified Radiator and a WCMods YT vid of how he does it using a small fountan pump, a Bucket and a filter. Which got me to thinking that maybe some of the cloudiness might be residual from the flushing of the Radiator. I know some people just use straight tap water, while some use Tap and Rinse w/Distilled and some use Vinegar mixed with distilled to rinse the left over Tap out of the system.
Also, to muddy this up a little more are your Rads new or used? Used could explain things some more if the method used was simply straight Tap water. Where I live the water is so high in mineral content that the Tea Kettle is calcified. It only gets filled via the Pur Filter that is on the Tap, but it's absolutely horrendous. It's to the point where the lid on the kettle sticks to the opening sometimes. So you know I'm not gonna be flushing with Tap here.
So if you would it would be much appreciated. Also relate any experiences regarding your Tap water as it may lead to figuring this out.
