Yeah I thought half the point of mud was over-researching things for your LC...and you've come to the right place to do so

My routine with a neglected cooling system. Flush, flush, flush (using a mild cleaner) and garden hose with Tstat removed, drive it, drain it, block and radiator every time, refill, drive it (heat control full hot), drain it. Then a couple of distilled water only flushes (3 gallons at a time), drive it, drain it. Replace Tstat, final fill 50:50 Toyota Red (whatever) and Distilled water. Drive it for 10 years. No issues.
I would not use any tap water for the final fill,
Toyota Red (whatever) and distilled water 50:50 after a thorough cleaning/flushing of the system = no problems.
The only concern here is that a garden hose is operating on 65 PSI and your cooling system is only designed for 14-16 PSI. Make sure you don't seal the hose tightly to anything and be sure to remove the thermostat when doing this.totally agree with this...
Garden hose flush FULL BLAST in every direction you can, then drain & very thoroughly replace/dilute the tapwater with distilled until the system is practically pure distilled, then drain just enough to make room for your gallon of 100% antifreeze of choice. top off with distilled - off you go.
A drain & replace 2-3 years later is an already clean system.
It's only 65 psi in a closed system. You'd be hard pressed to get 1psi if it's open.The only concern here is that a garden hose is operating on 65 PSI and your cooling system is only designed for 14-16 PSI.

Based on my research, almost no 2 coolants are the same. That's not to say that they are incompatible; like I stated in my research essay I think there are a couple that could be added to each other (like Prestone Prime "all vehicle", which is just ethylene and diethylene glycol). However unless you have the SDS's in front of you and know for a fact that they're compatible, I would not mix them. Also keep in mind that SDS's don't necessarily show all of the chemicals in a substance anyway. If you had an accident and lost some coolant, I'd say you are better off just adding water and then doing a flush/fill ASAP.Ok, so I know you should flush everything out if you want to go green to red, but what about green to another green like prestone green to zerex green? Still flush everything out?
Yeah that PSI drops pretty quick after it leaves the nozzle, although they do sell those systems where you can attach the hose to your radiator (or a few other places). I wouldn't use one of those.It's only 65 psi in a closed system. You'd be hard pressed to get 1psi if it's open.
Thank you - my point exactly - all that hose water gushing out some big hole somewhere, carrying any loose debris out with it.It's only 65 psi in a closed system. You'd be hard pressed to get 1psi if it's open.
Now there's a good idea! hadn't thought of that. - thus reducing the number of "residue dilution refills" needed.I'll add that if you want to get old tap water, or whatever other liquid, out of the cooling system after you've flushed it that you can set your shop vac up to blow and the place the hose on rad. hoses/etc. for a few minutes on each to blow most of the remaining fluids out.
