Tool required to replace serpentine belt on 1997 Ford 4.6 liter e
What tool is required to release the tension on the belt. The diagram on the 1997 Ford F250 shows a square hole in the tensioner, but it is not square. It feels round. I can't get a good look at it. On the diagram it says to use the lug adapter. What is that?

F-250 Belt Removal
Install a 16-mm (5/8-inch) closed end wrench for 7.5L engines or a 15-mm (19/32-inch) closed end wrench for 5.8L and 7.3L engines on the tensioner pulley bolt and lift the tensioner arm away from the belt.
Remove belt. Release tensioner arm slowly. Do not allow arm to snap back after the belt is removed because this may damage the tensioner.

need to take tension off spring loaded pulley with tool sometimes a bolt sometimes a square hole, find tool at parts store , follow diagram near hood latch for belt routing, release tension remove old , install new release tension , good to go
locate tensioner, a round pulley that kinda bounces when car running, to release tension either insert ratchet into square hole, or it may have a nut size 15mm, either way, it goes like this you have to take tool and pull tensioner pulley back, it will have slack in belt when pulled back, remember it is spring loaded!! if you're replacing the belt, have your diagram of belt routing handy, the belt will only go on one way! good luck!!!
No, some tensioner arms have a square hole for a 3/8 drive ratchet or breaker bar to be inserted into for releasing the tension to change the belt. If you do not see one (square hole) then I use the bolt in the center of the tensioner pulley, works every time. Hope this helps, let me know.
You have to find the belt tensioner. Then place a 3/8 th inch pull handle in the square hole on the tensioner body and push it away from the belt. Then slip the belt off of the tensioner pulley. It has a strong spring so make sure your hand is not pinched in something when you release the tensioner after the belt is removed. Some tensioners do not have a hole so you put a socket on the bolt holding the pulley.
There is a square hole on the tensioner that will allow you to use either a breaker bar or ratchet to release the tension on the belt. If your truck no longer has the belt routing diagram sticker on the shroud, be sure to take note of the belt's routing on the pulleys before you take it off.
go to gates.com and click on the Part Locator & Interchange link on the left, enter your vehicle information, look down and click the camera icon next to the serpintine belt, this is a diagram of how to route it. These engines have a tensioner pulley, it has a 3/8" square drive hole in it to release the tension on the belt, I start at the crankshaft and loop around leaving the tensioner for last, hope this helps, let me know
the belt tensioner is on the lower left of the engine there is a 1/2 drive square hole on the right hand side pulley arm to release the tension its a pain to get at but you can, sometimes it is easier from the bottom
The tensioner pully is a spring loaded arm and pully that rests against the belt.
You will find a square hole in the arm of the pully, this will fit a 3/8" ratchet drive.
You can use either the drive handle of a ratchet wrench, or a 3/8" drive breaker bar.
Snap the drive handle into the hole and turn in the direction that releases tension on the belt.
Make sure to release the arm slowly to avoid injury once the belt is off.
