Stuff in coolant

[Don Frelier]

There is your problem right there.

Please explain how tap water creates the substance he's shown. I don't think so.

Hard water deposits are not helping and probably causing the problems.

Calcium and/or minerals in water. Like what’s inside an old water heater.

I use ginger from the kitchen cabinet, lasts until you change coolant. Yes, get a filter in the top hose. Unless you pull your engine for overall, and heater core, radiator, be hard to collect all of that debris. Not changing your antifreeze in a timely manner and poor choice for water cause what you have. You should have seen my orginal Darts cooling system when I tore it down. Someone must have lived in mineral springs and never changed the coolant! There is Borax in the old antifreeze, maybe still is. When coolant isn't changed regularly and or poor water choice and PH ( acid) build up, that's what you get. Chunks. Reverse osmosis water is best, then distilled. Google it. Make sure that your new aluminum radiator fits.

I remember Ginger. Ginger Baker. I could us some Ginger right now. Man…
