Hey guys,
I'm finally the proud owner of an 07 Impreza WRX and absolutely love it! I've noticed however that whenever I do a cold start, there is a grinding noise coming from the passenger side of the engine bay that lasts for 10-30 seconds and then stops, only to return when the engine has fully cooled down.
Increasing the revs and pressing down the clutch doesn't seem to make a difference.
Everything seems fine when the noise has stopped and haven't had any other problems.
I think the source of the noise is coming from the part that I've circled in the image but I'm not 100% sure. I'm not too sure what this part is, any help would be much appreciated!
