did you try removing the alternator first? no i didn't try to remove the alternator first
The tension pulley should have a bolt that holds it on, allowing you to replace the unit.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
Take a 15mm open end wrench and fish it under the motor mount and place it on the nut to the tension pulley. Use a piece of wood or something to push down on the other end to get the leverage you need to relieve the tension on the pulley
You don't. The serpentine belt tension is automatically maintained by the tensioner pulley, which is an idler pulley located on the passenger side of the system and looks like it doesn't drive anything. If the belt tension is incorrect, the tensioner pulley must be replaced. If the question meant 'how to release tension from the belt' (for removal, etc.), this is done by applying the correct size socket wrench to the tensioner pulley's center nut and rocking the pulley away from the belt.
I HAD TO REPLACE MY SERPENTINE BELT BUT ENDED UP HAVING A MECHANIC DO IT FOR ME AND AT THE SAME TIME HE SAID THAT IT TOOK A SPECIAL TOOL TO REMOVE THE TENSION PULLY. THE TENSION SPRING ON THE PULLY HAD FROZEN. Ive replaced both the tensioner pulley and tensioner assembly on my 90 Dynasty 3.3 there are no special tools required its a 15mm both for both the pulley and assembly, tho there is a bit of patience required as neither is very easy to get to but its not terribly diffcult
You don't. If it has stretched too much for the tensioner pulley to handle, you need a new belt. Or, if the tensioner pulley is not applying correct tension, the tensioner pulley must be replaced.
The tension spring is broken, and the entire assembly must be replaced.
massage oils usually work and alot of alchahol will make the repalcement easier to handle.
Serpentine belts have a pulley that is spring loaded. Tension is set automatically when the belt is installed.
2.0L SOHC Engine: Disconnect the negative battery cable. Loosen the idle pulley's screw (it should be underneath the alternator on the same belt) just enough to remove the belt but not too much that the pulley falls. Put new belt, screw back the pulley, make sure tension is wright (with tension meter if you got one). If you don't have a tension meter then try to turn a pulley and see if the belt slips on it. If it does slip, then you'll have to screw the tension screw with a small 10 mm (I think) wrench. Plug back the negative cable. Run the car and listen to it. if it makes a squeaky sound, either the idle pulley is loose or the belt need an adjustment. Cheers
the idler pully makes the tension. to remove belt you use a wrench push tensioner in a direction that would loosen the belt as if you were trying to tighten or loosen the bolt holding the pulley on. carefull high tension.
how do i drop the oil pan from a 1998 dodge stratus 2.4 cylinder
