I bought them used, and they were not included per the instructions on AM, I should use these bolts. Does anyone know the size of the two bolts?

The water pump pulley bolts are 10mm head. The crank pulley bolt is 18mm head. The water pump bolts are re-useable. I would advise getting a new crank pulley bolt, p/n F5RZ-6A340-B, due to the torque specification it uses. Get a quality impact type of socket for the crank pulley- it's a bear to loosen and tighten. Good luck.

Just got one at ford

For future search - Above part number is correct for crank bolt... Never reuse the crank bolt per every post I’ve read... spend the $8 bucks.. you will need a 3 prong jaw puller; no drill holes in factory crank. Taking the intake off is all that's necessary. Fan shroud and radiator removal is not necessary... Put some rtv on key hole and a little grease on the shaft... torque method 67 lbs - 1 full turn back - 37 lbs and 1/4 turn forward...

Alternator bolt is m8x1.25x55 MM
