Re: Metal flakes in coolant? (anonx)
possibly bits of your motor, doubt it is a waterpump as I beleive the new water pump impellers are plastic. Hmmm, Would have to be foreign debris in the water jacket or cooling system. Radiator defect maybe. I would take it to a dealer right away and tell them that there is metal in your coolant, could be serious. Depends on the amount and the source.
