Hello, Pull the wheel, pull up the splash guard, then take a picture from that angle. Might be a better angle.

You need to...


Set the timing to the reference marks.

Remove both bolts

Remove the tensioner and compress it slowly, then insert the pin to hold it compressed.

Now see if the bolts will thread into those holes and chase or tap as needed.

Reinstall the tensioner and torque bolts to spec.

Pull the pin!

Here are some videos from Robertdiy on changing the timing belt. In the second video he talks about compressing the tensioner for reinstallation.

If you have not looked in there before and seen it fitted so it has the bolt head flush with the tensioner body, it could be someone has fitted a wrong bolt that is either too long or is short on thread.

Follow the info the guys have said. It is the only way to confirm what the issue is.
