Hello everyone,

Has anyone done a water pump replacement on their q60. Mine is making a chirping sound and I have a feeling it's one of the pulleys. I checked it out today and I did see some white specs on the engine block, I am assuming its coolant that is being flung by the rotation of the belt and is drying on the block. Also, about a month ago I changed out the two air filters, what's weird is that one if dirty already, but the other is clean.... Any thoughts? To the best of my knowledge, everything was snapped back into place correctly.

The white specs is probably just corrosion on the aluminum. It should be under warranty so I would suggest you take it in to be looked at.
