Place air ratchet w/ deep well 10mm socket on bolt of water pump, not seeing the cross member running between the frame rails is directly behind the head of the ratchet.

BTW, who makes a pneumatic ratchet that does NOT have the rotation switch on the back of the ratchet head??? After last Saturday, I've been in the market for one!!

Just thought y'all would enjoy a chuckle at my expense this morning. Have a good one!
