Flushing and reverse flushing questions!

[at0075]

Ok I'm getting ready to replace my oil cooler along with a egr delete and all the other goodies. I want to make sure my agenda looks like it suppose to. Im going to have to do the mega flush along with a reverse flush after. My coolant is the dirtiest Ive ever seen in a 6.0. Ok here it goes.

1. Coolant filter a week or so before my flush
2. Drain coolant by pulling lower radiator hose along with block drain plugs
3. Tap water flush until all old coolant is removed.
4. Tap water flush with restore, drain.
5. Tap water flush with vc9, drain.
6. Reverse flush for 30 minutes or so???
7. 7 to 8 flush cycles of distilled water
8. Then add 3.5 gallons of my elc and top with distilled water??

Someone please let me know if any of that is wrong because I want to do the job right and not half *** anything.

Now my next question is how long do I wait after to do my oil cooler? Can it be done right after if my deltas to high to drive or drive a week or so then change? Also do I have to drain the coolant again to do the oil cooler and egr delete. I guess if I do I will be only adding about 3.5 of pre mixed of elc and distilled or untill full. I know this is a much talked about subject and I have read a ton just want to sure up before I tear into her. Thanks

8.install new oil cooler, egr delete, any other work like STC fitting etc.
9. Then add 3.5 gallons of my elc and top with distilled water??

I did an oil cooler job last year without doing the correct flush. Noticed my delta was getting worse and worse. Finally hit about 17* doing the correct test. Did a restore and restore plus flush. Plus back flush by pouring restore directly into the oil cooler and using a pressure washer to flush out the oil cooler. Now my deltas only top about 9*. So oil cooler job may not be necessary. Thats just my experience, your procedure looks good though. Good luck.

I wouldn't worry about the reverse flush if your replacing the oil cooler. Only.other thing is you should put a coolant filter on and make sure the 3.5g of elf is concentrate. Everything.else sounds ok.

Thanks for the Advice guys. Pgreensvt that would be better replacing before Adding my new expensive coolant. Id hate to fill it up then drain it right back out. Pointless. Knock it all out at once seems to be the way to go IMO

Warchild, it wouldn't hurt to do the reverse anyways would it?. Every little bit I can do to drain some crap out of the system would be better. Even if it does push some stuff out of the old cooler before replacing. My system is so dirty that I have a feeling it will clog my new cooler up as well.

Befor till deciding on egr delete or bpd cooler. I'm trying to figure out my emissions. I run but it's only a obd test and they don't really have the equipment to test a diesel just a gas burner so I think I should be strait on that.

Also what are the flush cycle lengths? 1.5 hours per restore and vc9? And about 30 minutes per distilled cycles? Lastly, where can I get fumoto valves for my block drain plugs? It would help speed up the process IMO draining immediately after a flush cycle! I don't want to wait forever inbetween or get burned in the process. I got burned putting in my sending unit for my ect gauge in the block when I thought it was cool enough. WRONG
