Water pump failed, still finding particles in coolant
My coolant pump bearing failed/exploded a few weeks ago, after which I found a ton of particles in the coolant. Some of the particles were magnetic, some weren't. This makes sense to me since both the impeller and pump housing were heavily damaged.
I installed a new OEM pump and flushed the system *FIVE* times with blue BMW coolant and distilled water (50% ratio), but I'm still finding metal particles in the drained fluid. I even removed and reverse-flushed the radiator then cleaned out all of the hoses. It seems that no amount of flushing the system will get all of the metal particles out of there....
The metal particles can be seen suspended in the overflow reservoir, which tells me that they're light enough to circulate through the entire cooling tract. That being the case, the particles are going through the pump, too. My question for the forum is if I should be concerned by the remaining metal particles, or if I should just forget about it and see what happens?
The pump and all other parts came from FCP Euro, so I'm not concerned about cost if the new pump fails prematurely. I've driven it nearly every day since the repairs, and the coolant/oil temps are spot on. It's running beautifully.
Should I be concerned about the metal particles still remaining in my coolant system?
