Thanks for the link.

Missing 19mm bolt! Wow! I'm not there yet.

Much of what's covered in the link is in many others here.

I've had the car since '97 and have replaced the belt a few times + had it off for all sorts of other maint.

Equipped with all the proper factory tools for belt removal/reinstallation - understand the process.

As was mentioned in the link - this system is plagued with issues and sooner or later the tensioner is going to fail.

The one on my car is original - near 20 yrs. old.

I got my $$$ worth out of it.

Thanks for all of the input.
