Metallic coolant?? symptom of what?

That's a good question Joe, but I don't know. I'll be looking into it a little more over the next week. I'll see if it sticks to a magnet, it kinda has a gold color to it but it's probably the coolant making it look like that. I have some more pressing things to check out.... suspension started "clunking" around corners a couple of days ago (rebuilt the whole thing just over a year ago.)
Now that I think about it, the only thing that can cause "shavings" in the cooling system is the water pump as it's the only thing that moves right?

Thanks guys
