What bolt for this timing cover hole?

I just looked at an engine I had on the stand, and it has a standard bolt, with a washer. It looked to have at least .125" of clearance.
I know for a fact the water pump is a Advanced Auto replacement, so maybe it is the angle of the pump outlet to the bottom radiator hose.

Also use sealant on all the bolts to prevent leaks and the bolts down low that hold the power steering bracket to the timing chain cover are also in coolent.
