It's not casting sand. It's called "silicate dropout", and is what happens to SCA-based coolant (especially green). I saw none of that in my cooling system after running gold since being built, which is a hybrid-OAT coolant. It's partially SCA, partially ELC. But here's what dropout looks like -- if this is what you saw, it's time to switch to ELC!!

Are any of you running a coolant filter? I think the casting sand in some may be the reason for early water pump failure....
My original pump lasted about 83k miles, then I replaced it with NEW and did the 203* TStat, billet housing, and ELC (Red) coolant, and buy, the first time I changed the filter it had ALOT of crap in it!!
