Loosen the alternator tensioner bolt. You will be able to slide the alternator either way to adjust the tension on the belt.
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.
Ajustment bolt is located at the bottom of power steering pump.
The alternator belt is tension to about 12 pounds. This figure is however not a static figure.
Remove wiring harnesses, unbolt it, remove from engine. Install new alternator, apply tension using bar, bolt it, hookup wiring harnesses.
There is no idle pulley on 1995 GC's with 4.0 Inline 6. To replece the serpentine belt; 1) Draw a diagram of the existing routing. 2) Loosen the alternator. 3)Remove old belt and compare to the new belt. 4) Install new belt. 5) Tighten new belt by tightening alternator. on the 5.2 and 5.6 just rotate tension pulley to the right if you are standing in front of Jeep install and release the tension pulley and let it tighten
There is either a square hole in the tensioner for a breaker bar or a hex protruding from it that you can place a wrench on. Just pry against the spring tension.
Remove the upper through bolt of the alternator, remove the bottom bolt of the alternator by unscrewing the nut. Slide the belt off pulley. Install the new alternator. Replace and tighten the bolts (You will need to use a torque wrench to tighten to the proper foot-pounds of torque. You can find the torque specs for you bolts by going to a Honda forum). Adjust the tension bolt until there is enough tension on the belt (if not enough tension you will hear the belt squeak when you stat your car).
Changing the alternator on a Zafira is jsut like changing an alternator on any popular late model car. Unbolt it, make sure the belt comes off the pulley, and install a new alternator. Make sure to adjust the pulley to keep the correct tension on the belt
which pully do i remove tension to remove the alternator?
if you remove the moter Mount it is more accessible.
You need to loosen holding bolt on the alternator. After that loose tightening bolt (also on the alternator). And loose the bolt attaching the alternator to the body of the engine if you do not do that you will not be able to move the alternator. After that loose the tightening bolt until you will able to remove the belt. Make sure that the alternator is loosen enough to install a new belt. Install a new belt, use the tightening bolt to set tension in the belt. The rule of thumb is you should not be able to turn belt around itself more than 3/4 turns. Tighten other bolts.
Disconnect the battery. If your model uses a belt tensioner then move it to take the tension of the belt. Otherwise loosen the alternator bolts and the unit will move in its bracket to let you remove the belt. Disconnect alternator wiring and remove the alternator bolts to take the unit out. Reverse procedure to install the new unit.
If it is a serpentine belt, the tension is automatically adjusted by the tension idler. If the belt is loose then the tensioner needs replacing. If it is a normal drive belt, then the alternator is mounted on a slotted bracket that allows you to adjust the position of the alternator. You can loosen the bolts and adjust the tension on the belt.
There is a tensioner bolt that you need to geta wrench onto to loosen the tension on the belt. After that you get underneaththe vehicle and remove the retaining bolts and drop the alternator a little to disconnect the plug on the back. Install is reverse...
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
By loosening the tension on the alternator nut
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
If the alternator is driven by a drive belt, the answer is yes. You adjust the tension by loosing the bolts on the alternator mounting brackets and sliding the alternator until the proper tension, (around 1/4" deflection at mid point of the belt) is achieved. If however it has a Serpentine Belt driving the alternator, then there is no adjustment. Tension is held by the idler pulley. If it is loose then the belt is worn out, the idler tensioner is defective, or both.
using a 1/2" drive ratchet or breaker bar and release the tension on the sepantine belt and remove it. then disconnect the positive battery cable. start by removing the electrical connector plugged into the side/back of the alternator, then remove the nut and wire terminal on the back, then 3 bolts that hold it in. reverse the process to install.
Loosen the alternator mounting bolt and the tension-arm bolt. Push the alternator so the pulley tightens the belts. Tighten the tension-arm bolt, and then the mounting bolt.
Disconnect the negative battery cable. Loosen the anchor bolts on the alternator. Use a belt tension release tool (or a ratchet will work) to release the serpentine belt. Turn clockwise to release tension. Pull the belt off of the alternator. Disconnect the plug wire from the alternator. The release tab is on the back. Disconnect the ground. Remove the anchor bolts and pry the alternator out with a screw driver. Install the new alternator and go in reverse order. Connect the negative battery cable last. FYI it may help to use a standard screw driver to remove the air filter from the front of the motor and push aside. This will make it easier to access the belt tension pulley underneath.
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.
The tension bolt should not be removed. The four bolts holding the alternator in place need to be removed, the loosening tension bolt will give enough slack to get the belt off.
I came here looking to find the answer to that question. I'm switching out the alternator in my paseo. the housing needs to be loosened on the alternator to reduce tension on the belt and then the belt should slide off the side... there is very little tension to release so the belt is just kinda stuck... I'm going to get a screw driver and pry it off... how I'm going to get the belt back on is another story that I'll deal with this evening
