It was all 1 type unless my dad used something when i wasnt around. Glad im pulling the engine for a reseal and noticed it
 
Wash then in plain water and report back.
Did they disolve, are they hard, mushy .

MIGHT be cooling system sealer?

If you are brave touch one piece after washing to the tip of your young and report back on the taste, salty, dirty acidic,
 
Rinsing with water just cleaned them lol. They are semi hard like a wet clump of sand if that makes sense. Smashing them with my fingers they crumble easy into a sandy substance and then with water it dissolves. I did the taste test when i first found them. Almost no taste at all but a faint and i mean very faint saltiness
 
It's corrosion. The coolant isn't getting along with "something" in the system. What kind of antifreeze and what type radiator?
 
Take a piece and put it in viniger see if it desolves.


Either way I would get some cooling system cleaner and back flush the system.

Maybe even pull the rad and turn it upside down and flush it from the bottom outlet out through the rad cap hole and upper hose inlet.
 
Factory radiator. I pulled it and its clean as far as i can see. Im actually pulling the whole engine for other reasons so i will definitely flush it. Rusty i believe it was prestone green
 
I put some in vinegar so lets see. Here the thermostat after i removed it

Saw that only once before, was the mopar coolant. Some long life pink stuff.
Was like sand and rad was plugged.
My understanding was the water used was High mineral content.
That particular vehicle was from the southern usa, and sat for long periods of time.

de-mineralized water is best. Distilled and then soft water.
Better off with ditch water than well water….
 
The vinegar to this point has bleached the color out of them. They are pure white now like a crack rock lol. Maybe i could make a few bucks lmao. The well water thing is a good point. Im wondering if my dad topped it off at the farm. Its stored there and he has drove it a few times and they have a well
 
The 3 on the left are after vinegar the right one is what they looked like before

Hard water is still hard water even after a water softener…could make it worse for a cooling system.

You can always have more children......
 
Put your mouth on the thermostat outlet on the intake manifold and blow real hard to clean them out of the engine...
 
We've been out in the country now 20 years and well water is all I've ever used. I've never had any issues whatsoever. None. Zero. Zilch. This water is some of the hardest I've ever seen, too. Sure does taste good though. lol

I miss Virginia’s water, this water heats sucks.

I think it all depends on WHICH minerals are in the water as to how it reacts. Evidently I got lucky. I know I should use distilled water, but I never have and have never had an issue.
