Allen

 

It's an Allen 8mm....make sure it's a snug fit!
I had to go through a whole rigamarole to extract a damaged
plug....because some stooge couldn't use enough brain power to do it properly!!

Torx screws for the pan itself.
before trying to remove the Torx screws, it pays to go around
with bit in holder and use a hammer to tap each screw a couple of sharp
taps....they will loosen easier and less chance of snapping off screws
heads which happens occasionally....then it becomes a PIA! ;o]

 

I used a torx and it worked just fine. But your experience may vary.

 

pan bolts are torx fill and drain allen
