The idler tensioner pulley on your 1999 Ford F3 50 pickup truck is held in place with a single retaining bolt. The retaining bolt will go through the middle of the pulley. Tighten the retaining bolt to install the tensioner pulley.
Facing the engine the tensioner will be on left side of engine. There is an idler pulley that looks like the tensioner. The idler will have a smooth surface but the tensioner will have grooves on the pulley & should below the idler. If the tensioner is making noise etc it is prob just the tensioner pulley (grooved one) & you can get just the pulley. Big savings.
The idler pulley is near the top of the engine. Use a 15 MM (I think) socket on a long breaker bar, and turn the idler pulley arm so that the pulley moves away from the belt. You'll need to put the socket on the nut of the pulley, not on the arm itself. When the pulley is loose, you can pull the belt off. Some of the idler pulley arms have a square hole that accepts a 1/2 inch drive from a socket wrench breaker bar. But be careful. The serpentine belt routing is a little odd, and you'll want a picture to help you put it back. Make a drawing or take some pictures if you don't already have something from GM.
Standing in front of truck look to your below power steering pump you see a pulley that is your tenisorner pulley 15mm loosing the bolt on pulley above to the left is another 15mm also turn counter clock wise to loosen it this will help remove the belt

According to my internet research, to change the pitman and idler arm on a Chevy truck, one must remove the two bolts holding the idler arm as well as the nut holding it to the truck. Then to remove the pitman arm, remove the nut and the drag link.
Answer flasher on 89 ComancheIf you are referring to the blinker "flasher fuse", it is the bottom round fuse under the dash in the fuse block.
I have changed the idler pulley here recently on my 2001 ford ranger 3.0L, I dont know how off the top of my head, but a Haynes or Chilton's manual is the absolute best moneysaver you could ever buy for that truck. It will tell you how to tear it down and put it back together. They run about 15 bucks but it will pay for itself over and over again! I hope I could help.
Run the top half of the belt through the fan blades, rotate the fan 180 degrees, then pull that half back through the fan blades. Go around the crankcase pulley and the camshaft pulley, go under the tensioner pulley, over the AC compressor pulley, under the idler pulley, and back over the crankcase pulley. You'll need a 1/2" drive ratchet or breaker bar to adjust the tensioner.
