Hi Larse,

        Good point about the bolts possibly being a separate issue.  They may have been involved with the tire, but maybe Marcus has three separate issues to resolve.

The coolant leak,
The shutter 
And the loose CV bolts.

Bolts don’t just become loose, there had to be a reason. 

When I go under my van for one reason, say to change oil, I may find a ripped CV boot.  They are not connected but need attention.
