22mm socket. Good luck!
it would be a 19mm or a 22mm
27mm
30mm.
To loosen a bolt for removing the crank pulley, first ensure the vehicle is in gear or the parking brake is engaged to prevent the crankshaft from rotating. Use a socket wrench with the appropriate size socket, and if necessary, apply penetrating oil to the bolt to help with rust. If the bolt is particularly stubborn, you can tap the wrench with a hammer or use a breaker bar for added leverage. Remember to turn the bolt counterclockwise to loosen it.
I have a 99 4 cyl std tranny ranger. the crankshaft pulley bolt is 22mm. Am having problem loosening bolt. need special to lock crankshaft. I have a couple ot things to try.
You have to get a pulley puller of the appropriate size. Without a pulley you have no chance safely to remove it. Be careful do not deform the pulley it's not that hard as you can think.

There is a large metric bolt right (17 or 18mm) in the center of the main crank pulley. Immobilize the crank using a vise-grip equiped with a locking chain. Wrap an old fan belt (cut-to-size) around the crank and protect the serpentine gooves of the crank pulley, then wrap the vise chain and clamp onto the crank. Use a good breaker bar, or impact hammer to break the bolt torque free counter-clockwise. Note: Don't remove the four 10mm bolts on the crank pulley. The whole thing comes off as one assemble piece.
WORKING FROM THE FRONT; YOU NEED A SIZE 17 SOCKET ON A TBAR.THE ALTERNATER IS ON DRIVER SIDE AT THE BACK.THERE ARE THREE BOLTS TO LOOSEN (DONT TAKE THEM RIGHT OFF) . PULL THE ALTERNATER TOWARDS THE FRONT OF THE CAR, SLIP BELT OVER CRANK PULLEY THEN OVER ALTERNATER PULLEY .LEVER ALTERNATER BACK TO TIGHTEN BELT,THEN RETIGHTEN 3 BOLTS

To change the idler pulley on a 1994 Ford Bronco, first, ensure the engine is off and cool, then disconnect the negative battery cable. Use a socket wrench to relieve tension on the serpentine belt by rotating the tensioner pulley, and remove the belt from the idler pulley. Unbolt the old idler pulley using the appropriate socket size, then install the new pulley and reattach the serpentine belt following the routing diagram. Finally, reconnect the battery cable and start the engine to ensure everything is functioning properly.
Changing the size of the pulley can affect the motor's speed, depending on the specific configuration of the pulley system. If you increase the size of the driven pulley while keeping the drive pulley size constant, it will decrease the speed of the output shaft. Conversely, if you decrease the size of the driven pulley, it can increase the output speed. Thus, the relationship between pulley size and motor speed is inversely proportional in a basic pulley system.
