Last evening I was outside checking the oil level and looking making sure I had enough coolant, while looking into the top of the radiator I notice tiny foil like shavings in my coolant, upon closer inspection I noticed the coolant had little swirls of what seem to be very fine glitter. I ordered a water pump this morning. According to the factory gauge I am running at normal operating temp and, I haven't noticed any coolant leaking from the pump or anywhere else, and I don't smell coolant so no leaks (I only mention this because on other vehicles when the water pump has failed it has been a seal that has failed which leaked through a hole in the bottom). The only moving part where shavings could come from is the Pump right?
