Is cleaning a neglected system a [censored] when it comes to causing leaks?

I just changed coolant on a very neglected 96 Ford f150. It was so bad i didnt flush the system, just drained and refilled to avoid leaks.
,
I'd like to get the system clean, how would you handle it? Frequent changes? Filling system
with distilled water and driving, draining and refilling? Flushing? Or just frequent changes? Or infrequent to not disturb the crud possibly sealing the system?

Fill it with regular tap water, drive it a few days, then rinse and repeat until the water in there comes out clean. You're in coastal SC, so you won't have to worry about freezing for another 4-5 months yet.

I wouldn't use regular tap water in any cooling system. Anti-freeze also prevents corrosion and also raises the boiling point of the system, water would be 212 and a 50/50 mix would be 223. Also when it's under pressure, it's another 45 degrees higher.

I would use distilled water in place of tap water or just do a bunch of drain and fills.

If its that bad beg,borrow or steal a bazooka flush gun. I pull the block drains and bazooka the cooling system till it comes out clean.

Theres lots of rust stuck in the corners and lower edges of the block that cant be removed by just draining.Once your done with that you can run your distilled and coolant mix.

That seems cool, but wouldnt you be concerned about leaks?

Nothing wrong with straight water, the pressure in the system plus the waters boiling point is more than enough to cope with the heat. Plus the water holds more heat than Antifreeze so it should work better for short term while cleaning. I wouldn't be concerned with corrosion during a cleaning cycle.

Not necessarily.
I've used flush products and a flushing tee on neglected cooling systems without problems. If you do flush, make sure that you have the heater on high if this instalation uses a heater control valve.
Look at it this way.
A flush doesn't create leaks. It only makes them readily apparent.
Would you rather discover and fix the leaks now, or would you prefer that they reveal themselves when you're far from home?
Go ahead and flush the cooling system.
It'll probably be fine and if it isn't, you can fix anything that needs fixing in the comfort of your own driveway.
Also, unless you know that the themostat had been changed recently, change it while you have the system drained.
It's usually worth it to spend a little more for the OEM part.
You might want to replace the pressure cap as well and have a good look at the various hoses.

You've got two options, then.
Run a number of drain and fills with plain water until it comes out clean, or install a flushing tee, use a flush chemical and continue flowing water through the flushing tee until it comes out clean.
Citric acid is a good and safe cooling system cleaner.
Many dishwasher detergent booster are citric acid.
You can check labels and then use whatever's left in the dishwasher.

drain the radiator, fill it up, run the car for 10-15 mil, cool down, drain again and fill it up with tap water is fine ( garden hose ), run for day or 2, let it drain over night, next morning fill it up with coolant. or repeat drain and fill many time you like. you be fine running straight water for few day,

Getting creative may not be worth the risk or investment...

IMO, you've done more to lengthen the life of this truck by just changing the fluid. So long as you drained and refilled with a compatible fluid and you weren't overheating to begin with, the corrosion inhibitors you just added will be all this engine needs for now.

I tried being creative with an old Subie and ended up with a leaking coolant system when everything was fine before. I should have simply drained and refilled with Subie coolant (and Subie coolant conditioner) and called it good...

I would do a couple of drain & fills with G-05. If the truck experiencing any problems like overheating? That is when I might consider a flush chemical.

No overheating, but prior to the drain the indicated temp would raise slightly in traffic---but this was 100 degree. Heat gridlock traffic were talking about.
