i need to change my alternator belt and don't know where the tension wheel is so i can take off the other belt to replace the alternator belt on my 94 Mazda protege 1.6l
need to replace alternator on a ford expediting 2003
Apply a wrench to the center bolt on the pully and turn it will adjust the tension.
Loosen the alternator bolt and lean it forward to relief the tension there. Find the lock bolt on the front end of the assembly (just follow the belts) and you need to unscrew the locking bolt and then unscrew the tensioniner....it's near impossible to explain this without pictures.
The 93 Acclaim has a serpentine belt. The tensioner below the alternator is what keeps the tension. If you have not tension I would replace the belt first and then check the tensioner.
You must first loosen the alternator, do not remove it. remove the alternator tension screws top and loosen the bottom screws DO NOT REMOVE push the alternator toward engine, for the a/c belt you must loosen the belt tension pulley and move it. replace in reverse order
"First Remove the Tension bolt from the alternator and remove." "Next take a hammer and gently tap the alternator down" "Do the same with the Tension Mount" "After realigning the alternator and the Tension mount replace the bolt" "BE CAREFUL NOT TOO TIGHT ON THE BELT OR YOU WILL RUIN THE BEARINGS" "GOOD LUCK"
loosen the serpretine belt tension and remove the two bolt that hold the alternator
loosen the tension on the belt with the tension pulley, remove the belt then disconnect your wires from the alternator then take the 3-4 bolts, holding the alternator on, off. then do the opposite to put the new one back on
remove neg cable remove sensor that is located on top of alternator, move to one side still connected. remove power and reg cables on alt. loosen tension bolt remove bolt at bottom of alt. can do it from top behind alt. rewmove tension bolt and belt,work altr loose thru top between gas line and sensor that you moved, replace the same way
Release the tension using a wrench etc from the idler pulley.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
