I just changed mine on a 98 3.0 ranger. Mine was located on the same bracked as the air conditioner and the Power Steering pump. It is a smooth pully touches the smooth side of the belt and not the lines side of the belt.
Should have a spring loaded belt tensioner
place a wrench on the bolt in the center of the tensioner and push if you feel nothing push the other way and you will see that the whole assy is spring loaded and will move to release tension on the belt
Honda Man'sThere is no manual way to tighten the belt. The serpentine belt tensioner is spring loaded and requires no adjustment. If the belt is too loose replacing the belt tensioner will be required. it should tighten automaticly,you may need to replace the tensioner
there is a spring loaded tensioner. all you need is a wrench, like a 15 or 16mm. some are a little different but the concept is the same.
On the passenger's side of the engine down low there is a tensioner. It is a pulley mounted to a spring loaded arm. On the arm of that tensioner, there is a square hole to insert a small breaker bar or a ratchet. Insert the tool and use it to lever the tensioner and release the tension.
There is a spring-loaded tensioner pulley that keeps tension on the belt. The tensioner should have a place to fit a ratchet wrench or breaker bar (may or may not need a socket). The tensioner bar rotates clockwise or counterclockwise to release the tension on the belt. Be sure and note how the belt is routed so you will install the new belt in the same pattern. The tensioner is self-adjusting.
tension pullys have a small square in the side that a rachet will fit in.. they are "spring loaded" and if you put a ratchet in it you should be able to pull it back with ease and remove the belt hope this helps
The battery should be disconnected. The belt tensioner is spring loaded, using a socket and wrench, pull to the side to release the tension. Remove the old belt. Install the new belt over the pulleys the same direction that the old one went. Release tensioner and reconnect the battery.
The belt tensioner is automatic and does not need manual adjustment. Put a 15mm socket on the tensioner nut and push downward a few times. The internal tensioning spring should put it back into the tight position on the belt again. If it does not, then the tensioner needs replacement.
You have a 1999 Ford Ranger 3.0.
I have a ford escort with a zetic engine 1.6 1996, the serpentine belt tensioner is the free running pully that runs the belt between the crank wheel and the higher pully. its spring loaded, place a 14 or 15 mm ring spanner and move it has tigtenning the bolt. it must be done from the bottom as from the top there is no space. to have access to it you need to turn the wheel outwords and remove a plastic cover. on the rebuild fit the belt on the pullies except the AC one, bottom most pully at the front, then push the tensinoner back and place the last pully on. its spring loaded keep hands save.
