BUT what is the best way to flush system?
I will use Mayhems Oilblack, and i wonder what is the best way to flush all the parts.
I mean do i buy destil water and let it go with that for 2-3 hours and then i just empty the system?
What I do, or used to do, was heat distilled water in the microwave until it's hot - not boiling - and fill my rad ~1/3 full, cap it off, and shake shake shake (more like keep turning it back and forth and listen to the water rush from one end to the other each time) , then dump it in a white bucket / closed sink so I could inspect for debris. Then I'd repeat as many times as necessary until the water coming out was clear of anything I could see. Sometimes it's taken me ~5 or 6 times filling, shaking, and draining before I get no more debris that I can see, and then I'll do it again one last time just for good measure. That method is relatively cheap to do (a couple gallons of distilled is all), and works very well. I'm often surprised by how much junk comes out.
Many people do the same/similar as I described above but with tap water and just rinse with distilled/deionized when they are done. As I understand it, that's probably perfectly acceptable, and I haven't heard of anyone having any issues doing that, but distilled has always been so cheap where I live (I'm aware that in some parts of the world it isn't) that it just didn't make sense to me to put tap water in my rads just to save me the $0.75 a gallon I can get distilled for.
Anywho, the above method served me well quite a few times, but now what I do now is the same as above first, fill, shake, and dump, but just once, and then I have made a small filtration system that I use and I let it run for a few hours. I got the idea from skupples
, who apparently got it from a video by West Coast Mods
. It's probably a bit overkill but it gives me peace of mind that I shouldn't be clogging any of my blocks or ruining my pump with any radiator crud.Warning: Spoiler! (Click to show)
I bought everything for it on amazon or ebay:
