To make things easier I have created a YouTube video:
Can someone confirm that it is the water pump pulley and if the issue is what I have described?
Is it just me or does the bigger pulley look like its wobbling something fierce?
Sent from my iPhone 5s.
yes it looks like the water pump pulley does have some play in it in one form or other.
I think the best bet is to change the pulley/water pump if you think it is that. also as mentioned above add a new drive belt as well so all is new in that area.
