The tension pully is at the top of the front of the motor. (LEFT SIDE SINCE ITS TURNED.) You need a 1/2" breaker bar to get i believe. (I haven't done that in a while) The alternator is easy, there is a large screw in the back and a couple of wires to fight. If you get book from an Auto Store on the Achieva, it will show you. I have a Hanes book i believe. if you can understand the book, it will take you a 1/2 hr.

Apply a wrench to the center bolt on the pully and turn it will adjust the tension.

which pully do i remove tension to remove the alternator?

Serepentine bels do not have tension adjustments, there is a tension pully That is preloaded with a coil spring in it. If the belt is loose, the pully spring may have lost it tension. Replace the pully assembley.

This is a common problem on these vehicles. There is one pully keeping tension on the belt and another (opposite side) just going along for the ride. The most common culpret for the whining noise is the Idle pulley. It is cheap and easy to replace. 1) Take the belt of be releasing tension on the tension pully and slipping the belt off the alternator pully (no need to take belt completely off) 2) remove the center bolt on the pully and the pully will come right off 3) Bolt new pully on 4) Replace belt onto alternator pulley and make sure that it is riding correctly on all the other pulleys. 5) Release tentioner pully You are ready to go! Takes about 15 minutes. Now you can turn the radio down.

if the car doesn't have an automatic tensioner than if the belt is around the alternator pully you loosen the bolt holding the alternator on and move the alternator to tighten the belt.

User Avatar

you don't tighten a serpentine belt the tension is supplied by a tension pulley if belt is loose, it is time to replace belt or tension pully if tension pully needs repplacing belt will be worn anyway

While facing the engine the alternator is on the left side toward the front just below the plastic engine coolant container. It has a grooved belt that extends from the alternator pully down around the air conditioning compressor the rearwards to the crankshaft pully and finally it loops around the automatic tensioner pully which is just below the alternator. I replaced one on my sons 97' it's not too difficult but, trust me you will! need a special tool (a really long handled wrench that's used to push the tensioner pully toward the rear of the vehicle to relieve the tension on the belt so it can be removed.) Even with the tool its tricky but without it it's almost impossible. Hope this helps.

bottom left, next to the tension pully. must remove gravel shield to access

take a wrench to your tension pully so that you can release your belt. for safety you can detach your positive wire from battery. there are two wire plugs to take out of the alternator. then just take out the two bolts and just reverse process to put new one in,

Locate the idler spring tension pully below the power steering pump. The pully is pressing down on the belt and has to be pulled away from the belt so you can remove belt from the power steering or alternator pully. You need a socket that fits the bolt on the tension pully and a socket wrench with a 2 to 3 foot pipe extension. Attach to bolt head, apply counter clockwise pressure enought to loosen belt to allow enough slack to remove belt. Do not get your fingers between the belt and any pully when removing. You might not like it. To reinstall. Route the belt and release the tension again enough to put the belt back on the last pully.

first you should release the belt tension pully and remove the belt. Then the idler pully has a bolt through the center remove the bolt and the pully should come off.

to hook up an alternator with out ac just don't put the belt that hooks up to the crank pully back on.,.,

User Avatar

There is a pully that will ratchet up and down to loosen or tighten the belt. Take the belt off, unplug the wire from the alternator, and there should only be 2 or 3 bolts holding the alternator on.

if it is a serpentine belt, there is a tension pully that keeps it tight if is a v blet , u generally adjust the tension by moving the alternator

User Avatar

With a self adjusting tensioner pulley, there is no adjustment for tension.

User Avatar

there is no timing belt on a ford explorer If you mean the serpentine belt, use a socket to take the tension off of the tensioner pully wheel. There should be a diagram under the hood. After the tension is removed, you can remove the belt. Use the diagram to correctly reposition it. It runs the AC, Alternator, Fan, Water pump etc.

There's an idler wheel in the surpentine belt circuit along with the AC compressor, the main crank pully and the alternator. The purpose is to keep tension on the belt, and this idler is spring-loaded. If no serpentine belt diagram is available create one before beginning the steps below. In the center of the idler is a 15mm bolt head. Place a closed-end wrench on this bolt head with the free end pointed towards the front of the vehicle and pry the idler in an upwards motion. Hold the ider in the "up" position and slip the serpentine belt off of the alternator pully with the other hand. Release tension on the wrench slowly and allow the idler to lower to it's bottom stop.

I just did this the other day. you may need someone to help you. put a wrench on the tension pully bolt and move it as much as you can(counter clockwise). maybe use a metal tube over the wrench to get more leverage. once you have it loosened work the serpentine belt off of the alternator. if you use a screwdriver to work it off, be careful not to damage the belt. getting the belt back on is actually harder, try working it back on at the power steering pully instead of the alternator.

there should be a tensioner pully. Put the 3/8 ratchet in the center of it and turn.

User Avatar

Not hard to replace. Take intake tube off. Loosen the belt by rotation the tensioner Remove belt off pully Remove 3 bolts holding it on Take out & replace in reverse order Depending on the alt you may have to swap the alt pully

User Avatar

take off the serpentine belt by removing the tension from the pully let the tension back off should be 1 bolt holding on the tensioner on remove it and replace with a new one put the belt back on sometimes it is wise to make a digram of the belt routing first

User Avatar

It probably has a tension release pully, not a bolt. The pully has no function except tension. Your repair manual probably has instructions on changing the belt and a photo of the small pulley. Mary

User Avatar

open the hood-youll see the tension pully with the belt wraped around it and to the other pullies. youll need the right socket wrench to loosen the belt once accomplished-youll turn the nut on the pully to remove-go slowly and check the direction if correct. remove the tension pully insert the new one-put the screw back in=dont over tighten then place the belt back on-start your engine.

It is very hard to do but you will need a 12mm socket for the alternator and a long 12mm wrench to loosen the bolts on the other pully and a 10mm Allen wrench to adjust the A/C belt
