Tensioner replacement

Unfortunately, the manual does not list a specific process for this replacement as it should be straight forward.

Here is a guide that will help with general info:

Also, I am attaching the pictures below of the replacement part which sometimes helps with how to replace it. It appears there are four bolts.

Once these are removed, it should come off, but it may be on due to corrosion so you are putting a pry bar under a corner and once you break the corrosion, it will fall off if all the bolts are out.

Let me know if you have questions about this. Thanks
