Belt tensioner lower allen bolt..

[Ivan Demkovitch]

I don't think I can drill it out unless do it from the side of a head. May 
be some dremmel tool.
But again, I don't think there will be enough clearence to take tensioner 
out when head removed.

I think I will give this a try:

I will have to remove radiator fan though...
