I would remove one of the other bolts get a matching bolt from an auto part store or hardware store and torque down fairly tight. You’ll have an idea of torque from the bolt you removed.

the torque was different on each bolt, the previous owner did some work on that area and the torque is messed up.

I'd probably go with what @gogi said - take one out to find a replacement at Ace Hardware or similar and then use some common sense on tightening it (go until it's in there firmly, don't overtighten; use threadlocker if you see it on the bolts when you remove them)

The only thing I could find in the service manual was for the actual fan itself (see attachments)
