plastic in the coolant

Hello all, as the title says I have plastic in my coolant. I've had the car a few months now and have spent more time working on it than driving it. I have flushed the coolant and I am still finding small particles of orange brown plastic ( about the color of the end of the dipstick ) mostly small not much larger than a grain of sand. But some have come out about the size of a tictac. Any ideas what this could be?

I suspect someone has previously dumped a can of "stop leak" into the cooling system and you're seeing the residue from that.

I was going to suggest the same thing. Not good.

by the looks of it it is definitely not leak seal. However after looking at photos of the plastic water pump impellers, I believe that is what it is. any ideas on how to flush all of those large pieces out? I am going to try to pull it this weekend.

Could be. We were just trying to make a guess based on how you described it in text. The plastic water pump impellers don't typically fail like that. The impeller cracks around where the shaft is press into it and then stops turning causing an over heat, or the impeller breaks into bigger chunks. I think you'd have to ignore a failed water pump and the over heating for quite a while for the impeller to get ground up into little bits as you've described.

Keep us posted on what you find!

Do you have photos of the particles? Do they have sharp edges, or are they blobs?
