Bringing over some of my older tech posts to here. Hope these help.
Exact steps I took (overkill prob) as follows:
This took me about 2 hours to do on a huge ass tarp, Had about 4 five gallon buckets of waste water to be dropped off for recycling
System is now fully free of rust oil, sludge and mud. Coolant is perfect mixture and bright green.
As long as you dont let the acids sit in the system for an extended period it is safe for the mixed metal engines we have. I adapted this from a post on H.A.M.B, it worked flawlessly...system runs cooler, warms up faster and the heat works better. Its a great time to replace any sensors and hoses FYI

Exact steps I took (overkill prob) as follows:
- drain coolant from lower rad hose and block
- Block drain is near the oil drain pipe for the turbo connection on the block
- reconnect lower hose but leave block drain open
- open top of rad filling plug
- spray garden hose into filler on rad and overflow canister until it runs out of the block drain
- flush like this for a few min with cool water
- refit block drain
- fill with water and a tub of sulfamic acid (premixed)
- Warm up truck to operating temp and let idle for 20 or so min
- Drain above mixture
- fill with water and a tub of oxalic acid (premixed)
- Warm up truck to operating temp and let idle for 20 or so min
- Drain above mixture
- Flush again with garden hose
- Fill with water and a mixture of washing Soda (not baking soda)
- Warm up truck to operating temp and let idle for 20 or so min
- Drain above mixture
- Fill with garden hose again
- remove block drain then lower rad hose
- refit block drain and rad hose
- mix you choice of extended life coolant (I use standard green w/o silicates) and bottled distilled water
- Add bottle of anti cavitation additive for diesels
- Fill and bleed system
