Default Sediment in coolant overflow tank

I have a 2001 Ranger 2.5L engine. 235k miles on the radiator and all accessories. 125k on the engine. I keep getting sediment in the coolant tank every 1000 miles. Not much but enough to notice. I got a flush and it still happened. I waited about 3000 miles and went to the dealer since they claimed they use a better machine. After 500 miles there is sediment in there again. Dealer claimed the heater core is flushed too but it was only the service advisor that said that, so who really knows. I assume the service I had done should be under warranty, unless there's something else causing it.

Should I stop worrying about sediment or will it clog things up?

Does the radiator or something need to be replaced?

Suggestions?

Engine block is made out iron, rust.. I would not worry about it, just do your regular maintenance and you will be just fine. I would do it myself and stay away from the "STEALERSHIP". Just google it and I am sure you will find what. you need on YouTube.
