Anyone ever see this?
 

Pic of rad. what is it? !

Either coolant gel from contamination, silicate breakdown/drop out, some iron corrosion or aluminum corrosion. Silicate dropout (white gel, goo or chunks) happens when the antifreeze/coolant has been used beyond it life expectancy and the additives break down. Mixing different types of coolants can make some weird gel byproducts too. Or possibly some form of stop leak. Flush it well and use good quality coolant with soft water or filtered water.

If they are solid then a bad case of calcium depositing. This can be chemically flushed. Better put-a lime deposit.

I have seen plain water have soft clumps, but I have never seen antifreeze do that.

Looks like ice? Failed anti-freeze?

I was in Pontiac at a salvage yard, they bottle used oil and coolant and sell it for a $1 a gal in milk jugs, Unreal.

For what purpose?

Every gallon a bone yard sells is one gallon that doesn't soak into the ground at their site, plus, they don't have to pay to have it disposed of.

Double, or maybe even a triple win on their part.

To do whatever with - like add to or change your coolant. I used to see them all the time when I went to my local salvage yard. Beats $7 a gallon at Walmart. The ones I saw were all in at least what appeared to me as good condition. Nice green color with no sediments at the bottom of the container. Same for the Pink stuff. Here in NM we don't have a vehicle inspection requirement. So there are A LOT of beaters on the road. Never saw any used motor oil for sale though. I assume they drain that and sell it to the local guy who picks up used oil at places like Jiffy Lube.

The oil in you car is the best place to cut corners to save 10.00. ? LOL
